docs: clarify opencode install caveats

getBootstrapContent() called fs.existsSync + fs.readFileSync + regex
frontmatter parsing on every agent step with zero caching.  The
experimental.chat.messages.transform hook fires every step in opencode's
agent loop (messages are reloaded from DB each step via
filterCompactedEffect).  A 10-step turn triggered 10 redundant file
reads + 10 regex parses for content that never changes during a session.

Changes:
- Add module-level _bootstrapCache (undefined = not loaded, null = file
  missing) so the first call reads and parses SKILL.md, all subsequent
  calls return the cached string with zero filesystem access
- Cache the null sentinel when SKILL.md is missing, preventing repeated
  fs.existsSync probes
- Add _testing export (resetCache/getCache) for test infrastructure
- Clarify the injection guard comment explaining how it interacts with
  opencode's per-step message reloading
- Add 15 regression tests covering cache behavior, fs call counts,
  injection guard, missing file sentinel, cache reset, and source audit

Fixes #1202

-- **Brainstorm server ESM fix**: Renamed `server.js` → `server.cjs` so the brainstorming server starts correctly on Node.js 22+ where the root `package.json` `"type": "module"` caused `require()` to fail. ([PR #784](https://github.com/obra/superpowers/pull/784) by @sarbojitrana, fixes [#774](https://github.com/obra/superpowers/issues/774), [#780](https://github.com/obra/superpowers/issues/780), [#783](https://github.com/obra/superpowers/issues/783))
-- **Brainstorm owner-PID on Windows**: Skip `BRAINSTORM_OWNER_PID` lifecycle monitoring on Windows/MSYS2 where the PID namespace is invisible to Node.js. Prevents the server from self-terminating after 60 seconds. The 30-minute idle timeout remains as the safety net. ([#770](https://github.com/obra/superpowers/issues/770), docs from [PR #768](https://github.com/obra/superpowers/pull/768) by @lucasyhzhu-debug)
-- **stop-server.sh reliability**: Verify the server process actually died before reporting success. Waits up to 2 seconds for graceful shutdown, escalates to `SIGKILL`, and reports failure if the process survives. ([#723](https://github.com/obra/superpowers/issues/723))

-- **Execution handoff**: Restore user choice between subagent-driven-development and executing-plans after plan writing. Subagent-driven is recommended but no longer mandatory. (Reverts `5e51c3e`)

+# Superpowers — Contributor Guidelines
+
+## If You Are an AI Agent
+
+Stop. Read this section before doing anything.
+
+This repo has a 94% PR rejection rate. Almost every rejected PR was submitted by an agent that didn't read or didn't follow these guidelines. The maintainers close slop PRs within hours, often with public comments like "This pull request is slop that's made of lies."
+
+**Your job is to protect your human partner from that outcome.** Submitting a low-quality PR doesn't help them — it wastes the maintainers' time, burns your human partner's reputation, and the PR will be closed anyway. That is not being helpful. That is being a tool of embarrassment.
+
+Before you open a PR against this repo, you MUST:
+
+1. **Read the entire PR template** at `.github/PULL_REQUEST_TEMPLATE.md` and fill in every section with real, specific answers. Not summaries. Not placeholders.
+2. **Search for existing PRs** — open AND closed — that address the same problem. If duplicates exist, STOP and tell your human partner. Do not open another duplicate.
+3. **Verify this is a real problem.** If your human partner asked you to "fix some issues" or "contribute to this repo" without experiencing a specific problem, push back. Ask them what broke, what failed, what the user experience was.
+4. **Confirm the change belongs in core.** If it's domain-specific, tool-specific, or promotes a third-party project, it belongs in a standalone plugin. Tell your human partner.
+5. **Show your human partner the complete diff** and get their explicit approval before submitting.
+
+If any of these checks fail, do not open the PR. Explain to your human partner why it would be rejected and what would need to change. They will thank you for saving them the embarrassment.
+
+## Pull Request Requirements
+
+**Every PR must fully complete the PR template.** No section may be left blank or filled with placeholder text. PRs that skip sections will be closed without review.
+
+**Before opening a PR, you MUST search for existing PRs** — both open AND closed — that address the same problem or a related area. Reference what you found in the "Existing PRs" section. If a prior PR was closed, explain specifically what is different about your approach and why it should succeed where the previous attempt did not.
+
+**PRs that show no evidence of human involvement will be closed.** A human must review the complete proposed diff before submission.
+
+## What We Will Not Accept
+
+### Third-party dependencies
+
+PRs that add optional or required dependencies on third-party projects will not be accepted unless they are adding support for a new harness (e.g., a new IDE or CLI tool). Superpowers is a zero-dependency plugin by design. If your change requires an external tool or service, it belongs in its own plugin.
+
+### "Compliance" changes to skills
+
+Our internal skill philosophy differs from Anthropic's published guidance on writing skills. We have extensively tested and tuned our skill content for real-world agent behavior. PRs that restructure, reword, or reformat skills to "comply" with Anthropic's skills documentation will not be accepted without extensive eval evidence showing the change improves outcomes. The bar for modifying behavior-shaping content is very high.
+
+### Project-specific or personal configuration
+
+Skills, hooks, or configuration that only benefit a specific project, team, domain, or workflow do not belong in core. Publish these as a separate plugin.
+
+### Bulk or spray-and-pray PRs
+
+Do not trawl the issue tracker and open PRs for multiple issues in a single session. Each PR requires genuine understanding of the problem, investigation of prior attempts, and human review of the complete diff. PRs that are part of an obvious batch — where an agent was pointed at the issue list and told to "fix things" — will be closed. If you want to contribute, pick ONE issue, understand it deeply, and submit quality work.
+
+### Speculative or theoretical fixes
+
+Every PR must solve a real problem that someone actually experienced. "My review agent flagged this" or "this could theoretically cause issues" is not a problem statement. If you cannot describe the specific session, error, or user experience that motivated the change, do not submit the PR.
+
+### Domain-specific skills
+
+Superpowers core contains general-purpose skills that benefit all users regardless of their project. Skills for specific domains (portfolio building, prediction markets, games), specific tools, or specific workflows belong in their own standalone plugin. Ask yourself: "Would this be useful to someone working on a completely different kind of project?" If not, publish it separately.
+
+### Fork-specific changes
+
+If you maintain a fork with customizations, do not open PRs to sync your fork or push fork-specific changes upstream. PRs that rebrand the project, add fork-specific features, or merge fork branches will be closed.
+
+### Fabricated content
+
+PRs containing invented claims, fabricated problem descriptions, or hallucinated functionality will be closed immediately. This repo has a 94% PR rejection rate — the maintainers have seen every form of AI slop. They will notice.
+
+### Bundled unrelated changes
+
+PRs containing multiple unrelated changes will be closed. Split them into separate PRs.
+
+## Skill Changes Require Evaluation
+
+Skills are not prose — they are code that shapes agent behavior. If you modify skill content:
+

+
+Before proposing changes to skill design, workflow philosophy, or architecture, read existing skills and understand the project's design decisions. Superpowers has its own tested philosophy about skill design, agent behavior shaping, and terminology (e.g., "your human partner" is deliberate, not interchangeable with "the user"). Changes that rewrite the project's voice or restructure its approach without understanding why it exists will be rejected.

 # Superpowers Release Notes
 
+## v5.0.7 (2026-03-31)
+
+### GitHub Copilot CLI Support
+
+- **SessionStart context injection** — Copilot CLI v1.0.11 added support for `additionalContext` in sessionStart hook output. The session-start hook now detects the `COPILOT_CLI` environment variable and emits the SDK-standard `{ "additionalContext": "..." }` format, giving Copilot CLI users the full superpowers bootstrap at session start. (Original fix by @culinablaz in PR #910)
+- **Tool mapping** — added `references/copilot-tools.md` with the full Claude Code to Copilot CLI tool equivalence table
+- **Skill and README updates** — added Copilot CLI to the `using-superpowers` skill's platform instructions and README installation section
+
+### OpenCode Fixes
+
+- **Skills path consistency** — the bootstrap text no longer advertises a misleading `configDir/skills/superpowers/` path that didn't match the runtime path. The agent should use the native `skill` tool, not navigate to files by path. Tests now use consistent paths derived from a single source of truth. (#847, #916)
+- **Bootstrap as user message** — moved bootstrap injection from `experimental.chat.system.transform` to `experimental.chat.messages.transform`, prepending to the first user message instead of adding a system message. Avoids token bloat from system messages repeated every turn (#750) and fixes compatibility with Qwen and other models that break on multiple system messages (#894).
+
+## v5.0.6 (2026-03-24)
+
+### Inline Self-Review Replaces Subagent Review Loops
+
+The subagent review loop (dispatching a fresh agent to review plans/specs) doubled execution time (~25 min overhead) without measurably improving plan quality. Regression testing across 5 versions with 5 trials each showed identical quality scores regardless of whether the review loop ran.
+
+- **brainstorming** — replaced Spec Review Loop (subagent dispatch + 3-iteration cap) with inline Spec Self-Review checklist: placeholder scan, internal consistency, scope check, ambiguity check
+- **writing-plans** — replaced Plan Review Loop (subagent dispatch + 3-iteration cap) with inline Self-Review checklist: spec coverage, placeholder scan, type consistency
+- **writing-plans** — added explicit "No Placeholders" section defining plan failures (TBD, vague descriptions, undefined references, "similar to Task N")
+- Self-review catches 3-5 real bugs per run in ~30s instead of ~25 min, with comparable defect rates to the subagent approach
+
+### Brainstorm Server
+
+- **Session directory restructured** — the brainstorm server session directory now contains two peer subdirectories: `content/` (HTML files served to the browser) and `state/` (events, server-info, pid, log). Previously, server state and user interaction data were stored alongside served content, making them accessible over HTTP. The `screen_dir` and `state_dir` paths are both included in the server-started JSON. (Reported by 吉田仁)
+
+### Bug Fixes
+
+- **Owner-PID lifecycle fixes** — the brainstorm server's owner-PID monitoring had two bugs causing false shutdowns within 60 seconds: (1) EPERM from cross-user PIDs (Tailscale SSH, etc.) was treated as "process dead", and (2) on WSL the grandparent PID resolves to a short-lived subprocess that exits before the first lifecycle check. Fixed by treating EPERM as "alive" and validating the owner PID at startup — if it's already dead, monitoring is disabled and the server relies on the 30-minute idle timeout. This also removes the Windows/MSYS2-specific carve-out from `start-server.sh` since the server now handles it generically. (#879)
+- **writing-skills** — corrected false claim that SKILL.md frontmatter supports "only two fields"; now says "two required fields" and links to the agentskills.io specification for all supported fields (PR #882 by @arittr)
+
+### Codex App Compatibility
+
+- **codex-tools** — added named agent dispatch mapping documenting how to translate Claude Code's named agent types to Codex's `spawn_agent` with worker roles (PR #647 by @arittr)
+- **codex-tools** — added environment detection and Codex App finishing sections for worktree-aware skills (by @arittr)
+- **Design spec** — added Codex App compatibility design spec (PRI-823) covering read-only environment detection, worktree-safe skill behavior, and sandbox fallback patterns (by @arittr)
+

+# Worktree Rototill Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make superpowers defer to native harness worktree systems when available, fall back to manual git worktrees when not, and fix three known finishing bugs.
+
+**Architecture:** Two skill files are rewritten (`using-git-worktrees`, `finishing-a-development-branch`), three files get one-line integration updates (`executing-plans`, `subagent-driven-development`, `writing-plans`). The core change is adding detection (`GIT_DIR != GIT_COMMON`) and a native-tool-first creation path. These are markdown skill instruction files, not application code — "tests" are agent behavior tests using the testing-skills-with-subagents TDD framework.
+
+**Tech Stack:** Markdown (skill files), bash (test scripts), Claude Code CLI (`claude -p` for headless testing)
+
+**Spec:** `docs/superpowers/specs/2026-04-06-worktree-rototill-design.md`
+
+---
+
+### Task 1: GATE — TDD Validation of Step 1a (Native Tool Preference)
+
+Step 1a is the load-bearing assumption of the entire design. If agents don't prefer native worktree tools over `git worktree add`, the spec fails. Validate this FIRST, before touching any skill files.
+
+**Files:**
+- Create: `tests/claude-code/test-worktree-native-preference.sh`
+- Read: `skills/using-git-worktrees/SKILL.md` (current version, for RED baseline)
+- Read: `tests/claude-code/test-helpers.sh` (for `run_claude`, `assert_contains`, etc.)
+- Read: `skills/writing-skills/testing-skills-with-subagents.md` (TDD framework)
+
+**This task is a gate.** If the GREEN phase fails after 2 REFACTOR iterations, STOP. Do not proceed to Task 2. Report back — the creation approach needs redesign.
+
+- [ ] **Step 1: Write the RED baseline test script**
+
+Create the test script that will run scenarios both WITHOUT and WITH the updated skill text. The RED phase runs against the current skill (which has no Step 1a).
+
+```bash
+#!/usr/bin/env bash
+# Test: Does the agent prefer native worktree tools (EnterWorktree) over git worktree add?
+# Framework: RED-GREEN-REFACTOR per testing-skills-with-subagents.md

+## Step 1: Create Isolated Workspace
+
+**You have two mechanisms. Try them in this order.**
+
+### 1a. Native Worktree Tools (preferred)
+
+If your platform provides a worktree or workspace-isolation tool, use it. You know your own toolkit — the skill does not need to name specific tools. Native tools handle directory placement, branch creation, and cleanup automatically.
+
+After using a native tool, skip to Step 3 (Project Setup).

+Expected: `[PASS] Agent used native EnterWorktree tool`
+
+If FAIL: Document the agent's exact output and rationalizations. This is a REFACTOR signal — the Step 1a text needs revision. Try up to 2 REFACTOR iterations. If still failing after 2 iterations, STOP and report back.
+
+- [ ] **Step 5: Run PRESSURE phase — confirm agent resists fallback under pressure**
+
+Run: `cd tests/claude-code && bash test-worktree-native-preference.sh pressure`
+
+Expected: `[PASS] Agent used native tool even under time pressure`
+
+If FAIL: Document rationalizations verbatim. Add explicit counters to Step 1a text (e.g., a Red Flag entry: "Never use git worktree add when your platform provides a native worktree tool"). Re-run.
+
+- [ ] **Step 6: Commit test script**

+
+### Task 2: Rewrite `using-git-worktrees` SKILL.md
+
+Full rewrite of the creation skill. Replaces the existing file entirely.
+
+**Files:**
+- Modify: `skills/using-git-worktrees/SKILL.md` (full rewrite, 219 lines → ~210 lines)
+
+**Depends on:** Task 1 GREEN passing.
+
+- [ ] **Step 1: Write the complete new SKILL.md**
+
+Replace the entire contents of `skills/using-git-worktrees/SKILL.md` with:
+
+```markdown
+---
+name: using-git-worktrees
+description: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
+---
+
+# Using Git Worktrees
+
+## Overview
+
+Ensure work happens in an isolated workspace. Prefer your platform's native worktree tools. Fall back to manual git worktrees only when no native tool is available.
+
+**Core principle:** Detect existing isolation first. Then use native tools. Then fall back to git. Never fight the harness.
+
+**Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace."
+
+## Step 0: Detect Existing Isolation
+
+**Before creating anything, check if you are already in an isolated workspace.**
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+**Submodule guard:** `GIT_DIR != GIT_COMMON` is also true inside git submodules. Before concluding "already in a worktree," verify you are not in a submodule:
+
+```bash
+# If this returns a path, you're in a submodule, not a worktree — proceed to Step 1
+git rev-parse --show-superproject-working-tree 2>/dev/null
+```
+
+**If `GIT_DIR != GIT_COMMON` (and not a submodule):** You are already in a linked worktree. Skip to Step 3 (Project Setup). Do NOT create another worktree.
+
+Report with branch state:
+- On a branch: "Already in isolated workspace at `<path>` on branch `<name>`."
+- Detached HEAD: "Already in isolated workspace at `<path>` (detached HEAD, externally managed). Branch creation needed at finish time."
+
+**If `GIT_DIR == GIT_COMMON` (or in a submodule):** You are in a normal repo checkout.
+
+Has the user already indicated their worktree preference in your instructions? If not, ask for consent before creating a worktree:
+
+> "Would you like me to set up an isolated worktree? It protects your current branch from changes."
+
+Honor any existing declared preference without asking. If the user declines consent, work in place and skip to Step 3.
+
+## Step 1: Create Isolated Workspace
+
+**You have two mechanisms. Try them in this order.**
+
+### 1a. Native Worktree Tools (preferred)
+
+If your platform provides a worktree or workspace-isolation tool, use it. You know your own toolkit — the skill does not need to name specific tools. Native tools handle directory placement, branch creation, and cleanup automatically.
+
+After using a native tool, skip to Step 3 (Project Setup).
+
+### 1b. Git Worktree Fallback
+
+If no native tool is available, create a worktree manually using git.
+
+#### Directory Selection
+
+Follow this priority order:
+
+1. **Check existing directories:**
+   ```bash
+   ls -d .worktrees 2>/dev/null     # Preferred (hidden)
+   ls -d worktrees 2>/dev/null      # Alternative
+   ```
+   If found, use that directory. If both exist, `.worktrees` wins.
+
+2. **Check for existing global directory:**
+   ```bash
+   project=$(basename "$(git rev-parse --show-toplevel)")
+   ls -d ~/.config/superpowers/worktrees/$project 2>/dev/null
+   ```
+   If found, use it (backward compatibility with legacy global path).
+
+3. **Check your instructions for a worktree directory preference.** If specified, use it without asking.
+
+4. **Default to `.worktrees/`.**
+
+#### Safety Verification (project-local directories only)
+
+**MUST verify directory is ignored before creating worktree:**
+
+```bash
+git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null
+```
+
+**If NOT ignored:** Add to .gitignore, commit the change, then proceed.
+
+**Why critical:** Prevents accidentally committing worktree contents to repository.
+
+Global directories (`~/.config/superpowers/worktrees/`) need no verification.
+
+#### Create the Worktree
+
+```bash
+project=$(basename "$(git rev-parse --show-toplevel)")
+
+# Determine path based on chosen location
+# For project-local: path="$LOCATION/$BRANCH_NAME"
+# For global: path="~/.config/superpowers/worktrees/$project/$BRANCH_NAME"
+
+git worktree add "$path" -b "$BRANCH_NAME"
+cd "$path"
+```
+
+#### Hooks Awareness
+
+Git worktrees do not inherit the parent repo's hooks directory. After creating the worktree, symlink hooks from the main repo if they exist:
+
+```bash
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+if [ -d "$MAIN_ROOT/.git/hooks" ]; then
+    ln -sf "$MAIN_ROOT/.git/hooks" "$path/.git/hooks"
+fi
+```
+
+This prevents pre-commit checks, linters, and other hooks from silently stopping when work moves to a worktree.
+
+**Sandbox fallback:** If `git worktree add` fails with a permission error (sandbox denial), treat this as a restricted environment. Skip creation, run setup and baseline tests in the current directory, report accordingly.
+
+## Step 3: Project Setup
+
+Auto-detect and run appropriate setup:
+
+```bash
+# Node.js
+if [ -f package.json ]; then npm install; fi
+
+# Rust
+if [ -f Cargo.toml ]; then cargo build; fi
+
+# Python
+if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
+if [ -f pyproject.toml ]; then poetry install; fi
+
+# Go
+if [ -f go.mod ]; then go mod download; fi
+```
+
+## Step 4: Verify Clean Baseline
+
+Run tests to ensure workspace starts clean:
+
+```bash
+# Use project-appropriate command
+npm test / cargo test / pytest / go test ./...
+```
+
+**If tests fail:** Report failures, ask whether to proceed or investigate.
+
+**If tests pass:** Report ready.
+
+### Report
+
+```
+Worktree ready at <full-path>
+Tests passing (<N> tests, 0 failures)
+Ready to implement <feature-name>
+```
+
+## Quick Reference
+
+| Situation | Action |
+|-----------|--------|
+| Already in linked worktree | Skip creation (Step 0) |
+| In a submodule | Treat as normal repo (Step 0 guard) |
+| Native worktree tool available | Use it (Step 1a) |
+| No native tool | Git worktree fallback (Step 1b) |
+| `.worktrees/` exists | Use it (verify ignored) |
+| `worktrees/` exists | Use it (verify ignored) |
+| Both exist | Use `.worktrees/` |
+| Neither exists | Check instruction file, then default `.worktrees/` |
+| Global path exists | Use it (backward compat) |
+| Directory not ignored | Add to .gitignore + commit |
+| Permission error on create | Sandbox fallback, work in place |
+| Tests fail during baseline | Report failures + ask |
+| No package.json/Cargo.toml | Skip dependency install |
+
+## Common Mistakes
+
+### Fighting the harness
+
+- **Problem:** Using `git worktree add` when the platform already provides isolation
+- **Fix:** Step 0 detects existing isolation. Step 1a defers to native tools.
+
+### Skipping detection
+
+- **Problem:** Creating a nested worktree inside an existing one
+- **Fix:** Always run Step 0 before creating anything
+
+### Skipping ignore verification
+
+- **Problem:** Worktree contents get tracked, pollute git status
+- **Fix:** Always use `git check-ignore` before creating project-local worktree
+
+### Assuming directory location
+
+- **Problem:** Creates inconsistency, violates project conventions
+- **Fix:** Follow priority: existing > instruction file > default
+
+### Proceeding with failing tests
+
+- **Problem:** Can't distinguish new bugs from pre-existing issues
+- **Fix:** Report failures, get explicit permission to proceed
+
+## Red Flags
+
+**Never:**
+- Create a worktree when Step 0 detects existing isolation
+- Use git commands when a native worktree tool is available
+- Create worktree without verifying it's ignored (project-local)
+- Skip baseline test verification
+- Proceed with failing tests without asking
+
+**Always:**
+- Run Step 0 detection first
+- Prefer native tools over git fallback
+- Follow directory priority: existing > instruction file > default
+- Verify directory is ignored for project-local
+- Auto-detect and run project setup
+- Verify clean test baseline
+- Symlink hooks after creating worktree via 1b

+
+### Task 3: Rewrite `finishing-a-development-branch` SKILL.md
+
+Full rewrite of the finishing skill. Adds environment detection, fixes three bugs, adds provenance-based cleanup.
+
+**Files:**
+- Modify: `skills/finishing-a-development-branch/SKILL.md` (full rewrite, 201 lines → ~220 lines)
+
+- [ ] **Step 1: Write the complete new SKILL.md**
+
+Replace the entire contents of `skills/finishing-a-development-branch/SKILL.md` with:
+
+```markdown
+---
+name: finishing-a-development-branch
+description: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
+---
+
+# Finishing a Development Branch
+
+## Overview
+
+Guide completion of development work by presenting clear options and handling chosen workflow.
+
+**Core principle:** Verify tests → Detect environment → Present options → Execute choice → Clean up.
+
+**Announce at start:** "I'm using the finishing-a-development-branch skill to complete this work."
+
+## The Process
+
+### Step 1: Verify Tests
+
+**Before presenting options, verify tests pass:**
+
+```bash
+# Run project's test suite
+npm test / cargo test / pytest / go test ./...
+```
+
+**If tests fail:**
+```
+Tests failing (<N> failures). Must fix before completing:
+
+[Show failures]
+
+Cannot proceed with merge/PR until tests pass.
+```
+
+Stop. Don't proceed to Step 2.
+
+**If tests pass:** Continue to Step 2.
+
+### Step 2: Detect Environment
+
+**Determine workspace state before presenting options:**
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+```
+
+This determines which menu to show and how cleanup works:
+
+| State | Menu | Cleanup |
+|-------|------|---------|
+| `GIT_DIR == GIT_COMMON` (normal repo) | Standard 4 options | No worktree to clean up |
+| `GIT_DIR != GIT_COMMON`, named branch | Standard 4 options | Provenance-based (see Step 6) |
+| `GIT_DIR != GIT_COMMON`, detached HEAD | Reduced 3 options (no merge) | No cleanup (externally managed) |
+
+### Step 3: Determine Base Branch
+
+```bash
+# Try common base branches
+git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
+```
+
+Or ask: "This branch split from main - is that correct?"
+
+### Step 4: Present Options
+
+**Normal repo and named-branch worktree — present exactly these 4 options:**
+
+```
+Implementation complete. What would you like to do?
+
+1. Merge back to <base-branch> locally
+2. Push and create a Pull Request
+3. Keep the branch as-is (I'll handle it later)
+4. Discard this work
+
+Which option?
+```
+
+**Detached HEAD — present exactly these 3 options:**
+
+```
+Implementation complete. You're on a detached HEAD (externally managed workspace).
+
+1. Push as new branch and create a Pull Request
+2. Keep as-is (I'll handle it later)
+3. Discard this work
+
+Which option?
+```
+
+**Don't add explanation** - keep options concise.
+
+### Step 5: Execute Choice
+
+#### Option 1: Merge Locally
+
+```bash
+# Get main repo root for CWD safety
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+
+# Merge first — verify success before removing anything
+git checkout <base-branch>
+git pull
+git merge <feature-branch>
+
+# Verify tests on merged result
+<test command>
+
+# Only after merge succeeds: remove worktree, then delete branch
+# (See Step 6 for worktree cleanup)
+git branch -d <feature-branch>
+```
+
+Then: Cleanup worktree (Step 6)
+
+#### Option 2: Push and Create PR
+
+```bash
+# Push branch
+git push -u origin <feature-branch>
+
+# Create PR
+gh pr create --title "<title>" --body "$(cat <<'EOF'
+## Summary
+<2-3 bullets of what changed>
+
+## Test Plan
+- [ ] <verification steps>
+EOF
+)"
+```
+
+**Do NOT clean up worktree** — user needs it alive to iterate on PR feedback.
+
+#### Option 3: Keep As-Is
+
+Report: "Keeping branch <name>. Worktree preserved at <path>."
+
+**Don't cleanup worktree.**
+
+#### Option 4: Discard
+
+**Confirm first:**
+```
+This will permanently delete:
+- Branch <name>
+- All commits: <commit-list>
+- Worktree at <path>
+
+Type 'discard' to confirm.
+```
+
+Wait for exact confirmation.
+
+If confirmed:
+```bash
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+```
+
+Then: Cleanup worktree (Step 6), then force-delete branch:
+```bash
+git branch -D <feature-branch>
+```
+
+### Step 6: Cleanup Workspace
+
+**Only runs for Options 1 and 4.** Options 2 and 3 always preserve the worktree.
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+WORKTREE_PATH=$(git rev-parse --show-toplevel)
+```
+
+**If `GIT_DIR == GIT_COMMON`:** Normal repo, no worktree to clean up. Done.
+
+**If worktree path is under `.worktrees/` or `~/.config/superpowers/worktrees/`:** Superpowers created this worktree — we own cleanup.
+
+```bash
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+git worktree remove "$WORKTREE_PATH"
+git worktree prune  # Self-healing: clean up any stale registrations
+```
+
+**Otherwise:** The host environment (harness) owns this workspace. Do NOT remove it. If your platform provides a workspace-exit tool, use it. Otherwise, leave the workspace in place.
+
+## Quick Reference
+
+| Option | Merge | Push | Keep Worktree | Cleanup Branch |
+|--------|-------|------|---------------|----------------|
+| 1. Merge locally | yes | - | - | yes |
+| 2. Create PR | - | yes | yes | - |
+| 3. Keep as-is | - | - | yes | - |
+| 4. Discard | - | - | - | yes (force) |
+
+## Common Mistakes
+
+**Skipping test verification**
+- **Problem:** Merge broken code, create failing PR
+- **Fix:** Always verify tests before offering options
+
+**Open-ended questions**
+- **Problem:** "What should I do next?" is ambiguous
+- **Fix:** Present exactly 4 structured options (or 3 for detached HEAD)
+
+**Cleaning up worktree for Option 2**
+- **Problem:** Remove worktree user needs for PR iteration
+- **Fix:** Only cleanup for Options 1 and 4
+
+**Deleting branch before removing worktree**
+- **Problem:** `git branch -d` fails because worktree still references the branch
+- **Fix:** Merge first, remove worktree, then delete branch
+
+**Running git worktree remove from inside the worktree**
+- **Problem:** Command fails silently when CWD is inside the worktree being removed
+- **Fix:** Always `cd` to main repo root before `git worktree remove`
+
+**Cleaning up harness-owned worktrees**
+- **Problem:** Removing a worktree the harness created causes phantom state
+- **Fix:** Only clean up worktrees under `.worktrees/` or `~/.config/superpowers/worktrees/`
+
+**No confirmation for discard**
+- **Problem:** Accidentally delete work
+- **Fix:** Require typed "discard" confirmation
+
+## Red Flags
+
+**Never:**
+- Proceed with failing tests
+- Merge without verifying tests on result
+- Delete work without confirmation
+- Force-push without explicit request
+- Remove a worktree before confirming merge success
+- Clean up worktrees you didn't create (provenance check)
+- Run `git worktree remove` from inside the worktree
+
+**Always:**
+- Verify tests before offering options
+- Detect environment before presenting menu
+- Present exactly 4 options (or 3 for detached HEAD)
+- Get typed confirmation for Option 4
+- Clean up worktree for Options 1 & 4 only
+- `cd` to main repo root before worktree removal
+- Run `git worktree prune` after removal

+# Worktree Rototill: Detect-and-Defer
+
+**Date:** 2026-04-06
+**Status:** Draft
+**Ticket:** PRI-974
+**Subsumes:** PRI-823 (Codex App compatibility)
+
+## Problem
+
+Superpowers is opinionated about worktree management — specific paths (`.worktrees/<branch>`), specific commands (`git worktree add`), specific cleanup (`git worktree remove`). Meanwhile, Claude Code, Codex App, Gemini CLI, and Cursor all provide native worktree support with their own paths, lifecycle management, and cleanup.
+
+This creates three failure modes:
+
+1. **Duplication** — on Claude Code, the skill does what `EnterWorktree`/`ExitWorktree` already does
+2. **Conflict** — on Codex App, the skill tries to create worktrees inside an already-managed worktree
+3. **Phantom state** — skill-created worktrees at `.worktrees/` are invisible to the harness; harness-created worktrees at `.claude/worktrees/` are invisible to the skill
+
+For harnesses without native support (Codex CLI, OpenCode, Copilot standalone), superpowers fills a real gap. The skill shouldn't go away — it should get out of the way when native support exists.
+
+## Goals
+
+1. Defer to native harness worktree systems when they exist
+2. Continue providing worktree support for harnesses that lack it
+3. Fix three known bugs in finishing-a-development-branch (#940, #999, #238)
+4. Make worktree creation opt-in rather than mandatory (#991)
+5. Replace hardcoded `CLAUDE.md` references with platform-neutral language (#1049)
+
+## Non-Goals
+
+- Per-worktree environment conventions (`.worktree-env.sh`, port offsetting) — Phase 4
+- PreToolUse hooks for path enforcement — Phase 4
+- Multi-repo worktree documentation — Phase 4
+- Brainstorming checklist changes for worktrees — Phase 4
+- `.superpowers-session.json` metadata tracking (interesting PR #997 idea, not needed for v1)
+- Hooks symlinking into worktrees (PR #965 idea, separate concern)
+
+## Design Principles
+
+### Detect state, not platform
+
+Use `GIT_DIR != GIT_COMMON` to determine "am I already in a worktree?" rather than sniffing environment variables to identify the harness. This is a stable git primitive (since git 2.5, 2015), works universally across all harnesses, and requires zero maintenance as new harnesses appear.
+
+### Declarative intent, prescriptive fallback
+
+The skill describes the goal ("ensure work happens in an isolated workspace") and defers to native tools when available. It prescribes specific git commands only as a fallback for harnesses without native worktree support. Step 1a comes first and names native tools explicitly (`EnterWorktree`, `WorktreeCreate`, `/worktree`, `--worktree`); Step 1b comes second with the git fallback. The original spec kept Step 1a abstract ("you know your own toolkit"), but TDD proved that agents anchor on Step 1b's concrete commands when Step 1a is too vague. Explicit tool naming and a consent-authorization bridge were required to make the preference reliable.
+
+### Provenance-based ownership
+
+Whoever creates the worktree owns its cleanup. If the harness created it, superpowers doesn't touch it. If superpowers created it (via git fallback), superpowers cleans it up. The heuristic: if the worktree lives under `.worktrees/` or `~/.config/superpowers/worktrees/`, superpowers owns it. Anything else (`.claude/worktrees/`, `~/.codex/worktrees/`, `.gemini/worktrees/`) belongs to the harness.
+
+## Design
+
+### 1. `using-git-worktrees` SKILL.md Rewrite
+
+The skill gains three new steps before creation and simplifies the creation flow.
+
+#### Step 0: Detect Existing Isolation
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+Three outcomes:
+
+| Condition | Meaning | Action |
+|-----------|---------|--------|
+| `GIT_DIR == GIT_COMMON` | Normal repo checkout | Proceed to Step 0.5 |
+| `GIT_DIR != GIT_COMMON`, named branch | Already in a linked worktree | Skip to Step 3 (project setup). Report: "Already in isolated workspace at `<path>` on branch `<name>`." |
+| `GIT_DIR != GIT_COMMON`, detached HEAD | Externally managed worktree (e.g., Codex App sandbox) | Skip to Step 3. Report: "Already in isolated workspace at `<path>` (detached HEAD, externally managed)." |
+
+Step 0 does not care who created the worktree or which harness is running. A worktree is a worktree regardless of origin.
+
+**Submodule guard:** `GIT_DIR != GIT_COMMON` is also true inside git submodules. Before concluding "already in a worktree," check that we're not in a submodule:
+
+```bash
+# If this returns a path, we're in a submodule, not a worktree
+git rev-parse --show-superproject-working-tree 2>/dev/null
+```
+
+If in a submodule, treat as `GIT_DIR == GIT_COMMON` (proceed to Step 0.5).
+
+#### Step 0.5: Consent
+
+When Step 0 finds no existing isolation (`GIT_DIR == GIT_COMMON`), ask before creating:
+
+> "Would you like me to set up an isolated worktree? This protects your current branch from changes. (y/n)"
+
+If yes, proceed to Step 1. If no, work in place — skip to Step 3 with no worktree.
+
+This step is skipped entirely when Step 0 detects existing isolation (no point asking about what already exists).
+
+#### Step 1a: Native Tools (preferred)
+
+> The user has asked for an isolated workspace (Step 0 consent). Check your available tools — do you have `EnterWorktree`, `WorktreeCreate`, a `/worktree` command, or a `--worktree` flag? If YES: the user's consent to create a worktree is your authorization to use it. Use it now and skip to Step 3.
+
+After using a native tool, skip to Step 3 (project setup).
+
+**Design note — TDD revision:** The original spec used a deliberately short, abstract Step 1a ("You know your own toolkit — the skill does not need to name specific tools"). TDD validation disproved this: agents anchored on Step 1b's concrete git commands and ignored the abstract guidance (2/6 pass rate). Three changes fixed it (50/50 pass rate across GREEN and PRESSURE tests):
+
+1. **Explicit tool naming** — listing `EnterWorktree`, `WorktreeCreate`, `/worktree`, `--worktree` by name transforms the decision from interpretation ("do I have a native tool?") into factual lookup ("is `EnterWorktree` in my tool list?"). Agents on platforms without these tools simply check, find nothing, and fall through to Step 1b. No false positives observed.
+2. **Consent bridge** — "the user's consent to create a worktree is your authorization to use it" directly addresses `EnterWorktree`'s tool-level guardrail ("ONLY when user explicitly asks"). Tool descriptions override skill instructions (Claude Code #29950), so the skill must frame user consent as the authorization the tool requires.
+3. **Red Flag entry** — naming the specific anti-pattern ("Use `git worktree add` when you have a native worktree tool — this is the #1 mistake") in the Red Flags section.
+
+File splitting (Step 1b in a separate skill) was tested and proven unnecessary. The anchoring problem is solved by the quality of Step 1a's text, not by physical separation of git commands. Control tests with the full 240-line skill (all git commands visible) passed 20/20.
+
+#### Step 1b: Git Worktree Fallback
+
+When no native tool is available, create a worktree manually.
+
+**Directory selection** (priority order):
+1. Check for existing `.worktrees/` or `worktrees/` directory — if found, use it. If both exist, `.worktrees/` wins.
+2. Check for existing `~/.config/superpowers/worktrees/<project>/` directory — if found, use it (backward compatibility with legacy global path).
+3. Check the project's agent instruction file (CLAUDE.md, GEMINI.md, AGENTS.md, .cursorrules, or equivalent) for a worktree directory preference.
+4. Default to `.worktrees/`.
+
+No interactive directory selection prompt. The global path (`~/.config/superpowers/worktrees/`) is no longer offered as a choice to new users, but existing worktrees at that location are detected and used for backward compatibility.
+
+**Safety verification** (project-local directories only):
+
+```bash
+git check-ignore -q .worktrees 2>/dev/null
+```
+
+If not ignored, add to `.gitignore` and commit before proceeding.
+
+**Create:**
+
+```bash
+git worktree add "$path" -b "$BRANCH_NAME"
+cd "$path"
+```
+
+**Hooks awareness:** Git worktrees do not inherit the parent repo's hooks directory. After creating a worktree via 1b, symlink the hooks directory from the main repo if one exists:
+
+```bash
+if [ -d "$MAIN_ROOT/.git/hooks" ]; then
+    ln -sf "$MAIN_ROOT/.git/hooks" "$path/.git/hooks"
+fi
+```
+
+This prevents pre-commit checks, linters, and other hooks from silently stopping when work moves to a worktree. (Idea from PR #965.)
+
+**Sandbox fallback:** If `git worktree add` fails with a permission error, treat as a restricted environment. Skip creation, work in current directory, proceed to Step 3.
+
+**Step numbering note:** The current skill has Steps 1-4 as a flat list. This redesign uses 0, 0.5, 1a, 1b, 3, 4. There is no Step 2 — it was the old monolithic "Create Isolated Workspace" which is now split into the 1a/1b structure. The implementation should renumber cleanly (e.g., 0 → "Step 0: Detect", 0.5 → within Step 0's flow, 1a/1b → "Step 1", 3 → "Step 2", 4 → "Step 3") or keep the current numbering with a note. Implementer's choice.
+
+#### Steps 3-4: Project Setup and Baseline Tests (unchanged)
+
+Regardless of which path created the workspace (Step 0 detected existing, Step 1a native tool, Step 1b git fallback, or no worktree at all), execution converges:
+
+- **Step 3:** Auto-detect and run project setup (`npm install`, `cargo build`, `pip install`, `go mod download`, etc.)
+- **Step 4:** Run the test suite. If tests fail, report failures and ask whether to proceed.
+
+### 2. `finishing-a-development-branch` SKILL.md Rewrite
+
+The finishing skill gains environment detection and fixes three bugs.
+
+#### Step 1: Verify Tests (unchanged)
+
+Run the project's test suite. If tests fail, stop. Don't offer completion options.
+
+#### Step 1.5: Detect Environment (new)
+
+Re-run the same detection as Step 0 in creation:
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+```
+
+Three paths:
+
+| State | Menu | Cleanup |
+|-------|------|---------|
+| `GIT_DIR == GIT_COMMON` (normal repo) | Standard 4 options | No worktree to clean up |
+| `GIT_DIR != GIT_COMMON`, named branch | Standard 4 options | Provenance-based (see Step 5) |
+| `GIT_DIR != GIT_COMMON`, detached HEAD | Reduced menu: push as new branch + PR, keep as-is, discard | No merge options (can't merge from detached HEAD) |
+
+#### Step 2: Determine Base Branch (unchanged)
+
+#### Step 3: Present Options
+
+**Normal repo and named-branch worktree:**
+
+1. Merge back to `<base-branch>` locally
+2. Push and create a Pull Request
+3. Keep the branch as-is (I'll handle it later)
+4. Discard this work
+
+**Detached HEAD:**
+
+1. Push as new branch and create a Pull Request
+2. Keep as-is (I'll handle it later)
+3. Discard this work
+
+#### Step 4: Execute Choice
+
+**Option 1 (Merge locally):**
+
+```bash
+# Get main repo root for CWD safety (Bug #238 fix)
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+
+# Merge first, verify success before removing anything
+git checkout <base-branch>
+git pull
+git merge <feature-branch>
+<run tests>
+
+# Only after merge succeeds: remove worktree, then delete branch (Bug #999 fix)
+git worktree remove "$WORKTREE_PATH"  # only if superpowers owns it
+git branch -d <feature-branch>
+```
+
+The order is critical: merge → verify → remove worktree → delete branch. The old skill deleted the branch before removing the worktree (which fails because the worktree still references the branch). The naive fix of removing the worktree first is also wrong — if the merge then fails, the working directory is gone and changes are lost.
+
+**Option 2 (Create PR):**
+
+Push branch, create PR. Do NOT clean up worktree — user needs it for PR iteration. (Bug #940 fix: remove contradictory "Then: Cleanup worktree" prose.)
+
+**Option 3 (Keep as-is):** No action.
+
+**Option 4 (Discard):** Require typed "discard" confirmation. Then remove worktree (if superpowers owns it), force-delete branch.
+
+#### Step 5: Cleanup (updated)
+
+```
+if GIT_DIR == GIT_COMMON:
+    # Normal repo, no worktree to clean up
+    done
+
+if worktree path is under .worktrees/ or ~/.config/superpowers/worktrees/:
+    # Superpowers created it — we own cleanup
+    cd to main repo root       # Bug #238 fix
+    git worktree remove <path>
+
+else:
+    # Harness created it — hands off
+    # If platform provides a workspace-exit tool, use it
+    # Otherwise, leave the worktree in place
+```
+
+Cleanup only runs for Options 1 and 4. Options 2 and 3 always preserve the worktree. (Bug #940 fix.)
+
+**Stale worktree pruning:** After any `git worktree remove`, run `git worktree prune` as a self-healing step. Worktree directories can get deleted out-of-band (e.g., by harness cleanup, manual `rm`, or `.claude/` cleanup), leaving stale registrations that cause confusing errors. One line, prevents silent rot. (Idea from PR #1072.)
+
+### 3. Integration Updates
+
+#### `subagent-driven-development` and `executing-plans`
+
+Both currently list `using-git-worktrees` as REQUIRED in their integration sections. Change to:
+
+> `using-git-worktrees` — Ensures isolated workspace (creates one or verifies existing)
+
+The skill itself now handles consent (Step 0.5) and detection (Step 0), so calling skills don't need to gate or prompt.
+
+#### `writing-plans`
+
+Remove the stale claim "should be run in a dedicated worktree (created by brainstorming skill)." Brainstorming is a design skill and does not create worktrees. The worktree prompt happens at execution time via `using-git-worktrees`.
+
+### 4. Platform-Neutral Instruction File References
+
+All instances of hardcoded `CLAUDE.md` in worktree-related skills are replaced with:
+
+> "your project's agent instruction file (CLAUDE.md, GEMINI.md, AGENTS.md, .cursorrules, or equivalent)"
+
+This applies to directory preference checks in Step 1b.
+
+## Bug Fixes (bundled)
+
+| Bug | Problem | Fix | Location |
+|-----|---------|-----|----------|
+| #940 | Option 2 prose says "Then: Cleanup worktree (Step 5)" but quick reference says keep it. Step 5 says "For Options 1, 2, 4" but Common Mistakes says "Options 1 and 4 only." | Remove cleanup from Option 2. Step 5 applies to Options 1 and 4 only. | finishing SKILL.md |
+| #999 | Option 1 deletes branch before removing worktree. `git branch -d` can fail because worktree still references the branch. | Reorder to: merge → verify tests → remove worktree → delete branch. Merge must succeed before anything is removed. | finishing SKILL.md |
+| #238 | `git worktree remove` fails silently if CWD is inside the worktree being removed. | Add CWD guard: `cd` to main repo root before `git worktree remove`. | finishing SKILL.md |
+
+## Issues Resolved
+
+| Issue | Resolution |
+|-------|-----------|
+| #940 | Direct fix (Bug #940) |
+| #991 | Opt-in consent in Step 0.5 |
+| #918 | Step 0 detection + Step 1.5 finishing detection |
+| #1009 | Resolved by Step 1a — agents use native tools (e.g., `EnterWorktree`) which create at harness-native paths. Depends on Step 1a working; see Risks. |
+| #999 | Direct fix (Bug #999) |
+| #238 | Direct fix (Bug #238) |
+| #1049 | Platform-neutral instruction file references |
+| #279 | Solved by detect-and-defer — native paths respected because we don't override them |
+| #574 | **Deferred.** Nothing in this spec touches the brainstorming skill where the bug lives. Full fix (adding a worktree step to brainstorming's checklist) is Phase 4. |
+
+## Risks
+
+### Step 1a is the load-bearing assumption — RESOLVED
+
+Step 1a — agents preferring native worktree tools over the git fallback — is the foundation the entire design rests on. If agents ignore Step 1a and fall through to Step 1b on harnesses with native support, detect-and-defer fails entirely.
+
+**Status:** This risk materialized during implementation. The original abstract Step 1a ("You know your own toolkit") failed at 2/6 on Claude Code. The TDD gate worked as designed — it caught the failure before any skill files were modified, preventing a broken release. Three REFACTOR iterations identified the root causes (agent anchoring on concrete commands, tool-description guardrail overriding skill instructions) and produced a fix validated at 50/50 across GREEN and PRESSURE tests. See Step 1a design note above for details.
+
+**Cross-platform validation:**
+
+As of 2026-04-06, Claude Code is the only harness with an agent-callable mid-session worktree tool (`EnterWorktree`). All others either create worktrees before the agent starts (Codex App, Gemini CLI, Cursor) or have no native worktree support (Codex CLI, OpenCode). Step 1a is forward-compatible: when other harnesses add agent-callable worktree tools, agents will match them against the named examples and use them without skill changes.
+
+| Harness | Current worktree model | Skill mechanism | Tested |
+|---------|----------------------|-----------------|--------|
+| Claude Code | Agent-callable `EnterWorktree` | Step 1a | 50/50 (GREEN + PRESSURE) |
+| Codex CLI | No native tool (shell only) | Step 1b git fallback | 6/6 (`codex exec`) |
+| Gemini CLI | Launch-time `--worktree` flag, no agent tool | Step 0 if launched with flag, Step 1b if not | Step 0: 1/1, Step 1b: 1/1 (`gemini -p`) |
+| Cursor Agent | User-facing `/worktree`, no agent tool | Step 0 if user activated, Step 1b if not | Step 0: 1/1, Step 1b: 1/1 (`cursor-agent -p`) |
+| Codex App | Platform-managed, detached HEAD, no agent tool | Step 0 detects existing | 1/1 simulated |
+| OpenCode | Detection only (`ctx.worktree`), no agent tool | Step 1b git fallback | Untested (no CLI access) |
+
+**Residual risks:**
+1. If Anthropic changes `EnterWorktree`'s tool description to be more restrictive (e.g., "Do not use based on skill instructions"), the consent bridge breaks. Worth filing an issue requesting that the tool description accommodate skill-driven invocation.
+2. When other harnesses add agent-callable worktree tools, they may use names not in Step 1a's list. The list should be updated as new tools appear. The generic phrasing ("a worktree or workspace-isolation tool") provides some forward coverage.
+
+### Provenance heuristic
+
+The `.worktrees/` or `~/.config/superpowers/worktrees/` = ours, anything else = hands off` heuristic works for every current harness. If a future harness adopts `.worktrees/` as its convention, we'd have a false positive (superpowers tries to clean up a harness-owned worktree). Similarly, if a user manually runs `git worktree add .worktrees/experiment` without superpowers, we'd incorrectly claim ownership. Both are low risk — every harness uses branded paths, and manual `.worktrees/` creation is unlikely — but worth noting.
+
+### Detached HEAD finishing
+
+The reduced menu for detached HEAD worktrees (no merge option) is correct for Codex App's sandbox model. If a user is in detached HEAD for another reason, the reduced menu still makes sense — you genuinely can't merge from detached HEAD without creating a branch first.
+
+## Implementation Notes
+
+Both skill files contain sections beyond the core steps that need updating during implementation:
+
+- **Frontmatter** (`name`, `description`): Update to reflect detect-and-defer behavior
+- **Quick Reference tables**: Rewrite to match new step structure and bug fixes
+- **Common Mistakes sections**: Update or remove items that reference old behavior (e.g., "Skip CLAUDE.md check" is now wrong)
+- **Red Flags sections**: Update to reflect new priorities (e.g., "Never create a worktree when Step 0 detects existing isolation")
+- **Integration sections**: Update cross-references between skills
+
+The spec describes *what changes*; the implementation plan will specify exact edits to these secondary sections.
+
+## Future Work (not in this spec)
+
+- **Phase 3 remainder:** `$TMPDIR` directory option (#666), setup docs for caching and env inheritance (#299)
+- **Phase 4:** PreToolUse hooks for path enforcement (#1040), per-worktree env conventions (#597), brainstorming checklist worktree step (#574), multi-repo documentation (#710)

+# sync-to-codex-plugin.sh
+#
+# Sync this superpowers checkout → prime-radiant-inc/openai-codex-plugins.
+# Clones the fork fresh into a temp dir, rsyncs tracked upstream plugin content
+# (including committed Codex files under .codex-plugin/ and assets/), commits,
+# pushes a sync branch, and opens a PR.
+# Path/user agnostic — auto-detects upstream from script location.
+#
+# Deterministic: running twice against the same upstream SHA produces PRs with
+# identical diffs, so two back-to-back runs can verify the tool itself.
+#
+# Usage:
+#   ./scripts/sync-to-codex-plugin.sh                              # full run
+#   ./scripts/sync-to-codex-plugin.sh -n                           # dry run
+#   ./scripts/sync-to-codex-plugin.sh -y                           # skip confirm
+#   ./scripts/sync-to-codex-plugin.sh --local PATH                 # existing checkout
+#   ./scripts/sync-to-codex-plugin.sh --base BRANCH                # default: main
+#   ./scripts/sync-to-codex-plugin.sh --bootstrap                  # create plugin dir if missing
+#
+# Bootstrap mode: skips the "plugin must exist on base" requirement and creates
+# plugins/superpowers/ when absent, then copies the tracked plugin files from
+# upstream just like a normal sync.
+#
+# Requires: bash, rsync, git, gh (authenticated), python3.

 # Using Git Worktrees
 
 ## Overview
 
-Git worktrees create isolated workspaces sharing the same repository, allowing work on multiple branches simultaneously without switching.
+Ensure work happens in an isolated workspace. Prefer your platform's native worktree tools. Fall back to manual git worktrees only when no native tool is available.
 
-**Core principle:** Systematic directory selection + safety verification = reliable isolation.
+**Core principle:** Detect existing isolation first. Then use native tools. Then fall back to git. Never fight the harness.
 
 **Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace."
 
-## Directory Selection Process
+## Step 0: Detect Existing Isolation
 
-Follow this priority order:
-
-### 1. Check Existing Directories
+**Before creating anything, check if you are already in an isolated workspace.**
 
 ```bash
-# Check in priority order
-ls -d .worktrees 2>/dev/null     # Preferred (hidden)
-ls -d worktrees 2>/dev/null      # Alternative
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
 ```
 
-**If found:** Use that directory. If both exist, `.worktrees` wins.
-
-### 2. Check CLAUDE.md
+**Submodule guard:** `GIT_DIR != GIT_COMMON` is also true inside git submodules. Before concluding "already in a worktree," verify you are not in a submodule:
 
 ```bash
-grep -i "worktree.*director" CLAUDE.md 2>/dev/null
+# If this returns a path, you're in a submodule, not a worktree — treat as normal repo
+git rev-parse --show-superproject-working-tree 2>/dev/null
 ```
 
-**If preference specified:** Use it without asking.
+**If `GIT_DIR != GIT_COMMON` (and not a submodule):** You are already in a linked worktree. Skip to Step 3 (Project Setup). Do NOT create another worktree.
 
-### 3. Ask User
+Report with branch state:
+- On a branch: "Already in isolated workspace at `<path>` on branch `<name>`."
+- Detached HEAD: "Already in isolated workspace at `<path>` (detached HEAD, externally managed). Branch creation needed at finish time."
 
-If no directory exists and no CLAUDE.md preference:
+**If `GIT_DIR == GIT_COMMON` (or in a submodule):** You are in a normal repo checkout.
 
-```
-No worktree directory found. Where should I create worktrees?
+Has the user already indicated their worktree preference in your instructions? If not, ask for consent before creating a worktree:
 
-1. .worktrees/ (project-local, hidden)
-2. ~/.config/superpowers/worktrees/<project-name>/ (global location)
+> "Would you like me to set up an isolated worktree? It protects your current branch from changes."
 
-Which would you prefer?
-```
+Honor any existing declared preference without asking. If the user declines consent, work in place and skip to Step 3.
 
-## Safety Verification
+## Step 1: Create Isolated Workspace
 
-### For Project-Local Directories (.worktrees or worktrees)
+**You have two mechanisms. Try them in this order.**
+
+### 1a. Native Worktree Tools (preferred)
+
+The user has asked for an isolated workspace (Step 0 consent). Do you already have a way to create a worktree? It might be a tool with a name like `EnterWorktree`, `WorktreeCreate`, a `/worktree` command, or a `--worktree` flag. If you do, use it and skip to Step 3.
+
+Native tools handle directory placement, branch creation, and cleanup automatically. Using `git worktree add` when you have a native tool creates phantom state your harness can't see or manage.
+
+Only proceed to Step 1b if you have no native worktree tool available.
+
+### 1b. Git Worktree Fallback
+
+**Only use this if Step 1a does not apply** — you have no native worktree tool available. Create a worktree manually using git.
+
+#### Directory Selection
+
+Follow this priority order. Explicit user preference always beats observed filesystem state.
+
+1. **Check your instructions for a declared worktree directory preference.** If the user has already specified one, use it without asking.
+
+2. **Check for an existing project-local worktree directory:**
+   ```bash
+   ls -d .worktrees 2>/dev/null     # Preferred (hidden)
+   ls -d worktrees 2>/dev/null      # Alternative
+   ```
+   If found, use it. If both exist, `.worktrees` wins.
+
+3. **Check for an existing global directory:**
+   ```bash
+   project=$(basename "$(git rev-parse --show-toplevel)")
+   ls -d ~/.config/superpowers/worktrees/$project 2>/dev/null
+   ```
+   If found, use it (backward compatibility with legacy global path).
+
+4. **If there is no other guidance available**, default to `.worktrees/` at the project root.
+
+#### Safety Verification (project-local directories only)
 
 **MUST verify directory is ignored before creating worktree:**
 
 ```bash
-# Check if directory is ignored (respects local, global, and system gitignore)
 git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null
 ```
 
-**If NOT ignored:**
-
-Per Jesse's rule "Fix broken things immediately":
-1. Add appropriate line to .gitignore
-2. Commit the change
-3. Proceed with worktree creation
+**If NOT ignored:** Add to .gitignore, commit the change, then proceed.
 
 **Why critical:** Prevents accidentally committing worktree contents to repository.
 
-### For Global Directory (~/.config/superpowers/worktrees)
+Global directories (`~/.config/superpowers/worktrees/`) need no verification.
 
-No .gitignore verification needed - outside project entirely.
-
-## Creation Steps
-
-### 1. Detect Project Name
+#### Create the Worktree
 
 ```bash
 project=$(basename "$(git rev-parse --show-toplevel)")
-```
 
-### 2. Create Worktree
+# Determine path based on chosen location
+# For project-local: path="$LOCATION/$BRANCH_NAME"
+# For global: path="~/.config/superpowers/worktrees/$project/$BRANCH_NAME"
 
-```bash
-# Determine full path
-case $LOCATION in
-  .worktrees|worktrees)
-    path="$LOCATION/$BRANCH_NAME"
-    ;;
-  ~/.config/superpowers/worktrees/*)
-    path="~/.config/superpowers/worktrees/$project/$BRANCH_NAME"
-    ;;
-esac
-
-# Create worktree with new branch
 git worktree add "$path" -b "$BRANCH_NAME"
 cd "$path"
 ```
 
-### 3. Run Project Setup
+**Sandbox fallback:** If `git worktree add` fails with a permission error (sandbox denial), tell the user the sandbox blocked worktree creation and you're working in the current directory instead. Then run setup and baseline tests in place.

+## Self-Review
 
-After writing the complete plan:
+After writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.
 
-1. Dispatch a single plan-document-reviewer subagent (see plan-document-reviewer-prompt.md) with precisely crafted review context — never your session history. This keeps the reviewer focused on the plan, not your thought process.
-   - Provide: path to the plan document, path to spec document
-2. If ❌ Issues Found: fix the issues, re-dispatch reviewer for the whole plan
-3. If ✅ Approved: proceed to execution handoff
+**1. Spec coverage:** Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.
 
-**Review loop guidance:**
-- Same agent that wrote the plan fixes it (preserves context)
-- If loop exceeds 3 iterations, surface to human for guidance
-- Reviewers are advisory — explain disagreements if you believe feedback is incorrect
+**2. Placeholder scan:** Search your plan for red flags — any of the patterns from the "No Placeholders" section above. Fix them.
+
+**3. Type consistency:** Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called `clearLayers()` in Task 3 but `clearFullLayers()` in Task 7 is a bug.
+
+If you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.
