Align Pi mapping with action vocabulary

Replace Claude-Code-specific tool names in skill prose, prompt
templates, and OpenCode-facing docs with action-language descriptions
that resolve to each runtime's native tool via the per-platform refs.

Changes by category:

- Prose mentions ("Use TodoWrite to track...", "Use Task tool with
  general-purpose type") → action language ("Track each item as a
  todo", "Dispatch a general-purpose subagent")

- Prompt template headers (6 files): "Task tool (general-purpose):"
  → "Subagent (general-purpose):" — preserves the type information
  without naming Claude Code's specific dispatch tool

- DOT flowchart node labels: "Invoke Skill tool" → "Invoke the
  skill"; "Create TodoWrite todo per item" → "Create a todo per
  item"

- OpenCode INSTALL.md and docs/README.opencode.md: replace the old
  "TodoWrite → todowrite, Task → @mention" mapping (which both
  taught a vocabulary skills no longer use AND was wrong about
  @mention being a real OpenCode syntax) with an action-language
  mapping verified against the installed OpenCode CLI's tool
  inventory.

The platform-tools refs landed in Phase B already document each
runtime's resolution; skills now speak in the actions those refs
map. Tool names that genuinely belong only in the per-platform
dispatch section ("In Claude Code: Use the `Skill` tool") and the
Claude-Code-specific Bash run_in_background flag note in
visual-companion remain — those are intentional carve-outs.

+# Pi Extension and Evals 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:** Add first-class Pi package support for Superpowers and add Pi as a Drill eval backend.
+
+**Architecture:** The Pi package is declared in the root `package.json` and loads existing `skills/` plus a small Pi extension. The extension injects the `using-superpowers` bootstrap into provider context as a user-role message on session startup and after compaction, with Pi-specific tool mapping. Drill gains a `pi` backend, Pi session-log normalization, and tests.
+
+**Tech Stack:** Pi TypeScript extension API, Node built-in test runner, Drill Python eval harness, pytest.
+
+---
+
+### Task 1: Pi package manifest and extension tests
+
+**Files:**
+- Modify: `package.json`
+- Create: `tests/pi/test-pi-extension.mjs`
+
+- [ ] **Step 1: Write failing package/extension tests**
+
+Create `tests/pi/test-pi-extension.mjs` with tests that import `extensions/superpowers.ts`, register fake Pi handlers, and assert:
+- root `package.json` has `keywords` containing `pi-package`
+- root `package.json` has `pi.skills: ["./skills"]`
+- root `package.json` has `pi.extensions: ["./extensions/superpowers.ts"]`
+- the extension registers `resources_discover`, `session_start`, `session_compact`, `context`, and `agent_end`
+- startup `context` injects exactly one user-role bootstrap message
+- `agent_end` clears startup injection
+- `session_compact` re-enables injection
+- the extension does not register `session_before_compact`
+
+- [ ] **Step 2: Run tests and verify RED**
+
+Run: `node --experimental-strip-types --test tests/pi/test-pi-extension.mjs`
+
+Expected: FAIL because `extensions/superpowers.ts` does not exist and `package.json` lacks the `pi` manifest.
+
+- [ ] **Step 3: Implement manifest fields**
+
+Update `package.json` with `description`, `keywords`, `pi.extensions`, and `pi.skills` while preserving existing `name`, `version`, `type`, and `main`.
+
+- [ ] **Step 4: Implement `extensions/superpowers.ts`**
+
+Create a zero-runtime-dependency extension that:
+- locates the package root from `import.meta.url`
+- reads `skills/using-superpowers/SKILL.md`
+- strips YAML frontmatter
+- appends Pi-specific tool mapping
+- exposes `resources_discover` with the skills path
+- marks bootstrap pending on `session_start` and `session_compact`
+- injects a user-role bootstrap message in `context`
+- inserts post-compact bootstrap after leading `compactionSummary` messages
+- clears pending bootstrap on `agent_end`
+
+- [ ] **Step 5: Run tests and verify GREEN**
+
+Run: `node --experimental-strip-types --test tests/pi/test-pi-extension.mjs`
+
+Expected: PASS.
+
+### Task 2: Pi tool mapping reference
+
+**Files:**
+- Create: `skills/using-superpowers/references/pi-tools.md`
+- Modify: `tests/pi/test-pi-extension.mjs`
+
+- [ ] **Step 1: Write failing test for Pi reference doc**
+
+Add assertions that `skills/using-superpowers/references/pi-tools.md` exists and documents mappings for `Skill`, `Task`, `TodoWrite`, and built-in tool names.
+
+- [ ] **Step 2: Run tests and verify RED**
+
+Run: `node --experimental-strip-types --test tests/pi/test-pi-extension.mjs`
+
+Expected: FAIL because `pi-tools.md` does not exist.
+
+- [ ] **Step 3: Add Pi reference doc**
+
+Create `skills/using-superpowers/references/pi-tools.md` explaining Pi-native skills, optional `pi-subagents`, no canonical todo/tasklist plugin, and built-in lowercase tools.

+- Modify: `evals/drill/backend.py`
+- Modify: `evals/drill/engine.py`
+- Modify: `evals/drill/normalizer.py`
+- Modify: `evals/tests/test_backend.py`
+- Modify: `evals/tests/test_normalizer.py`
+
+- [ ] **Step 1: Write failing backend/normalizer tests**
+
+Add pytest coverage for:
+- `load_backend("pi")` returns `family == "pi"`
+- Pi backend command starts with `pi` and includes `-e ${SUPERPOWERS_ROOT}`
+- `_resolve_log_dir()` for Pi points under `~/.pi/agent/sessions`
+- `filter_pi_logs_by_cwd()` keeps only session files whose header `cwd` matches the scenario workdir
+- `normalize_pi_logs()` extracts `toolCall` blocks from Pi assistant session entries and maps built-in lowercase tools to canonical names
+
+- [ ] **Step 2: Run tests and verify RED**
+
+Run: `uv run pytest evals/tests/test_backend.py evals/tests/test_normalizer.py -q`
+
+Expected: FAIL because the Pi backend and normalizer do not exist.
+
+- [ ] **Step 3: Add `evals/backends/pi.yaml`**
+
+Configure the backend to run `pi -e ${SUPERPOWERS_ROOT}`, use permissive TUI readiness, `/quit` shutdown, and Pi session log location.
+
+- [ ] **Step 4: Implement Pi family support**
+
+Update `Backend.family`, `Engine._resolve_log_dir`, `Engine._collect_tool_calls`, and `normalizer.py` with Pi log filtering and normalizing.

+# Platform-neutral config-file references — Phase B design
+
+## Background
+
+Phase A (see `2026-05-05-platform-neutral-prose-design.md`) replaced generic third-person "Claude" prose with agent-neutral forms. This phase tackles the next category: references to the per-platform instruction file (CLAUDE.md, AGENTS.md, GEMINI.md) inside skills.
+
+The plugin runs on multiple harnesses, and each one reads its own instruction file. Where a skill names CLAUDE.md as if it were the only file, that's a Claude-Code-centric assumption that doesn't hold on Codex / Gemini CLI / OpenCode.
+
+## In scope
+
+Two specific lines in active skills:
+
+1. **`skills/writing-skills/SKILL.md:58`** — `Project-specific conventions (put in CLAUDE.md)`
+2. **`skills/receiving-code-review/SKILL.md:30`** — `"You're absolutely right!" (explicit CLAUDE.md violation)`
+
+## Out of scope
+
+- **`skills/using-superpowers/SKILL.md:22, 26`** — instruction-priority list. The list already names all three (CLAUDE.md, GEMINI.md, AGENTS.md) inclusively, which is correct: the section is making a real claim about *what counts as user instruction* on a multi-platform plugin. No change needed.
+- **Historical / example artifacts**:
+  - `skills/systematic-debugging/CREATION-LOG.md` — attribution path (`~/.claude/CLAUDE.md`) is a historical fact.
+  - `skills/writing-skills/examples/CLAUDE_MD_TESTING.md` — the entire file is a worked example testing CLAUDE.md content variants. The filename, body, and the reference from `testing-skills-with-subagents.md` all stay; normalizing them defeats the example.
+- **Platform-tooling references** — Phase D candidates:
+  - `skills/using-superpowers/SKILL.md:40` (Gemini CLI tool mapping note about GEMINI.md)
+  - `skills/using-superpowers/references/gemini-tools.md` (`save_memory` persists to GEMINI.md)
+
+## Substitution rules
+
+Two distinct calls, one per in-scope line.
+
+### Rule 1: "where to put project-specific conventions"
+
+`writing-skills/SKILL.md:58`:
+
+- **Before:** `Project-specific conventions (put in CLAUDE.md)`
+- **After:** `Project-specific conventions (put in your instructions file)`
+
+Use a generic phrase rather than picking one filename. Different harnesses read different files (CLAUDE.md, AGENTS.md, GEMINI.md, etc.) and the skill should not assume one. The platform-tools reference docs (`references/{codex,copilot,gemini}-tools.md`) are the right place to name each platform's preferred file.
+
+### Rule 2: the "(explicit CLAUDE.md violation)" parenthetical
+
+`receiving-code-review/SKILL.md:30`:
+
+- **Before:** `"You're absolutely right!" (explicit CLAUDE.md violation)`
+- **After:** `"You're absolutely right!" (explicit instruction-file violation)`
+
+The parenthetical is doing real work — it signals this phrase isn't just stylistically bad, it actively violates rules many users put in their instruction files. "Instruction file" is the natural cross-platform term covering AGENTS.md / CLAUDE.md / GEMINI.md collectively, and keeps the original signal without picking one filename or softening to "common".
+
+## Commit plan
+
+Atomic commits, in order:
+
+1. **`writing-skills/SKILL.md`** — CLAUDE.md → "your instructions file" in the "where to put project conventions" line
+2. **`receiving-code-review/SKILL.md`** — CLAUDE.md → instruction-file in the violation parenthetical
+3. **Platform-tools reference docs** — add the preferred per-platform instructions filename (CLAUDE.md, AGENTS.md, GEMINI.md, etc.) to each `references/{codex,copilot,gemini}-tools.md` so readers can resolve "your instructions file" to a real filename.
+
+Each commit message names "Phase B" and the slice.
+
+## Verification
+
+After each commit:
+
+- Read the surrounding paragraph to confirm grammar and meaning still parse.
+- `grep -n "CLAUDE\.md" <touched-file>` — no remaining hits in active prose (carve-outs already documented).
+
+After both commits:
+
+- `grep -rn "CLAUDE\.md" skills/` should return only the documented carve-outs (CREATION-LOG, CLAUDE_MD_TESTING and its inbound reference, the priority list in using-superpowers).
+
+## Non-goals
+
+- Do not touch the priority list ordering in `using-superpowers/SKILL.md`. Reordering CLAUDE.md / GEMINI.md / AGENTS.md is an aesthetic change, not a substitution, and out of scope here.
+- Do not rename `examples/CLAUDE_MD_TESTING.md` or change its content.

+
+## Implementation note
+
+Phase B as written here covered three commits and the three non-Claude-Code platform-tools refs. Implementation went one step further: a fourth ref, `references/claude-code-tools.md`, was added in commit `8505703` for symmetry, so Claude Code's instructions-file conventions and tool-name list live alongside the others rather than implicitly in the surrounding skill prose. That addition wasn't anticipated in this spec but is consistent with its intent.

+# Platform-neutral prose — Phase A design
+
+## Background
+
+Superpowers ships to multiple agent runtimes (Claude Code, Codex, Cursor, OpenCode, Copilot CLI, Gemini CLI). Skill content and supporting docs were written first for Claude Code and use "Claude" in places where any runtime's agent applies. OpenAI's vendored fork (openai/plugins#217) attempted a wholesale rewrite that was actively wrong in places — rewriting historical attribution paths, model names, and platform-specific install instructions — and we want to avoid that mistake while still removing platform-centric prose where it is genuinely incidental.
+
+The full effort is broken into phases by reference category. **This spec covers Phase A only:** generic third-person prose mentioning "Claude" in non-platform-specific contexts. Later phases (config-file references, marketing copy, tool-name references) are out of scope here and will get their own specs.
+
+## In scope
+
+Generic prose mentions of "Claude" in:
+
+- `skills/*/SKILL.md` and supporting `.md` files in active skill directories
+- `skills/writing-skills/anthropic-best-practices.md`
+- `README.md` (only where the mention is generic prose, not platform marketing)
+
+Plus one coined-term rename: **Claude Search Optimization (CSO) → Skill Discovery Optimization (SDO)** in `skills/writing-skills/SKILL.md`.
+
+## Out of scope
+
+- **Platform/runtime statements** — "In Claude Code:", install instructions, tool-mapping references. (Phase D candidate.)
+- **Config-file references** — CLAUDE.md, AGENTS.md, GEMINI.md priority lists and "where to put project conventions" callouts. (Phase B.)
+- **Tool-name references** — `Skill`, `Bash`, `Read`, `Task`, `TodoWrite`. Skills are written in Claude Code's tool vocabulary; the existing `references/{codex,copilot,gemini}-tools.md` files map them. (At the time this spec was written, the plan was to defer or skip these. Phase E ended up doing them — replacing tool names with action language across active skills and unifying the platform-tools refs around the same vocabulary.)
+- **Marketing copy** in README — "Superpowers for Claude Code", platform-named install sections. (Phase C.)
+- **Historical artifacts** — `docs/plans/*.md`, `docs/superpowers/specs/*.md`, `CREATION-LOG.md`. These are dated, point-in-time documents; rewriting them rewrites history.
+- **Model identifiers** — Claude Haiku / Sonnet / Opus. These are real product names.
+- **Filename / URL references** — `CLAUDE.md`, `claude.com`, `claude-plugin/`, paths under `~/.claude/`.
+- **`anthropic-best-practices.md` filename** — the file remains named after its source even though we rewrite the prose inside it.
+
+## Replacement style
+
+Use a mix that reads naturally in English:
+
+- **Second person — "your agent"** when addressing the skill author about *their* runtime
+  - "your agent reads the description"
+- **Third person — "the agent" / "agents" / "an agent"** when describing system behavior generically
+  - "Future agents find your skills"
+  - "Use words an agent would search for"
+  - "Agents read SKILL.md only when the skill becomes relevant"
+
+Pick whichever fits the surrounding sentence; do not force consistency at the cost of awkward phrasing. Pluralize when natural ("future agents", "agents read") rather than always saying "the agent".
+
+### Carve-outs that stay as "Claude"
+
+- Model names: Claude Haiku, Claude Sonnet, Claude Opus
+- Filenames and URLs: `CLAUDE.md`, `claude.com`, `~/.claude/`
+- Branded platform name "Claude Code" wherever it refers to the runtime as such (handled in later phases)
+
+### Coined-term rename
+
+- **Claude Search Optimization (CSO) → Skill Discovery Optimization (SDO)**
+  - Appears in `skills/writing-skills/SKILL.md` as a section heading and in nearby prose. Rename the heading, the acronym, and any in-file cross-references.
+
+## Files affected
+
+Approximate counts based on a `grep` filtered to exclude carve-outs:
+
+| File | Generic-prose mentions |
+|------|------------------------|
+| `skills/writing-skills/SKILL.md` | ~12 (includes CSO heading + body) |
+| `skills/writing-skills/anthropic-best-practices.md` | ~30 |
+| `skills/writing-skills/examples/CLAUDE_MD_TESTING.md` | ~1 — filename stays (it's a CLAUDE.md test artifact); the "Variant C: Claude.AI Emphatic Style" heading also stays (it's a label naming a specific style) |
+| `README.md` | ~1 |
+
+Final list confirmed during implementation by re-running the filtered grep.
+
+## Commit plan
+
+Four atomic commits, in order:
+
+1. **Rename CSO → SDO** in `skills/writing-skills/SKILL.md`. Mechanical, isolated, easy to revert if we change our minds about the term.
+2. **Active skills prose** — generic "Claude" → "agent" forms across `skills/*/SKILL.md` and supporting `.md`, excluding `anthropic-best-practices.md`.
+3. **`anthropic-best-practices.md` prose** — same substitution rules. Separate commit because this file is a vendored adaptation of an external doc; isolating the change makes future reconciliation with upstream easier to read.
+4. **README.md prose** *(only if any generic-prose mentions remain after filtering)*. Skipped if empty.
+
+Each commit message names the phase ("Phase A") and the slice ("rename CSO to SDO", "agent prose in active skills", etc.) so the series is self-documenting.
+
+## Verification
+
+After each commit:
+
+- `grep -rn "Claude" <touched-paths>` — every remaining hit must fall into a documented carve-out (model name, filename, URL, "Claude Code" platform name, historical artifact).
+- Read the touched file end-to-end — substitutions should not have broken sentence flow, pronoun agreement, or list parallelism.
+- No tests to run; this is prose-only.
+
+After the final commit:
+
+- Skim each modified skill in a live session to confirm nothing reads awkwardly.
+
+## Non-goals
+
+- Do not change behavior, structure, headings (other than CSO→SDO), examples, code blocks, or YAML frontmatter.
+- Do not introduce new sections, callouts, or compatibility notes.
+- Do not "improve" prose beyond the substitution while editing.

+# Platform-neutral README ordering — Phase C design
+
+## Background
+
+Phases A and B (see `2026-05-05-platform-neutral-prose-design.md` and `2026-05-05-platform-neutral-config-refs-design.md`) already neutralized generic Claude prose and config-file references in the README. The remaining platform-leaning signal is layout: the README's two platform listings put Claude Code first and aren't strictly alphabetical elsewhere.
+
+This phase fixes the ordering. No prose changes.
+
+## In scope
+
+1. **Quickstart platform list** (`README.md:7`) — the inline link list of supported harnesses
+2. **Installation section ordering** (`README.md:35–152`) — the per-harness install sub-sections
+
+## Out of scope
+
+- Prose, marketplace names, plugin IDs, URLs — all factually correct as-is.
+- Visual weight of the Claude Code section (which has two sub-sections — official Anthropic marketplace and Superpowers marketplace). Both are real install paths; collapsing them would hide accurate info.
+- Section headings and content within each install block — only the ordering of the blocks changes.
+
+## Substitution
+
+Both listings reorder to strict alphabetical:
+
+| Old order | New order |
+|-----------|-----------|
+| Claude Code | Claude Code |
+| Codex CLI | Codex App |
+| Codex App | Codex CLI |
+| Factory Droid | Cursor |
+| Gemini CLI | Factory Droid |
+| OpenCode | Gemini CLI |
+| Cursor | GitHub Copilot CLI |
+| GitHub Copilot CLI | OpenCode |
+
+Three moves: Codex App swaps with Codex CLI; Cursor moves up two slots; GitHub Copilot CLI moves up one.
+
+Claude Code remains first by alphabetical chance (`Cl…` precedes `Co…`).
+
+## Commit plan
+
+One atomic commit covering both listings, since changing one without the other would create inconsistency between the quickstart and the installation section.
+
+## Verification
+
+- Quickstart anchors (`#claude-code`, `#codex-app`, etc.) still resolve to existing `### …` headings — no headings renamed.
+- Each install sub-section's body is byte-identical pre/post; only positions changed.
+- `git diff README.md` shows section moves only, no content edits.

+# Claude Code Tool Mapping
+
+Skills speak in actions ("dispatch a subagent", "create a todo", "read a file"). On Claude Code these resolve to the tools below.
+
+## Tools
+
+| Action skills request | Claude Code tool |
+|----------------------|------------------|
+| Read a file | `Read` |
+| Create a new file | `Write` |
+| Edit a file | `Edit` |
+| Run a shell command | `Bash` |
+| Search file contents | `Grep` |
+| Find files by name | `Glob` |
+| Fetch a URL | `WebFetch` |
+| Search the web | `WebSearch` |
+| Invoke a skill | `Skill` |
+| Dispatch a subagent (`Subagent (general-purpose):` template) | `Agent` (older releases named this `Task`) |
+| Multiple parallel dispatches | Multiple `Agent` calls in one response |
+| Task tracking ("create a todo", "mark complete") | `TaskCreate`, `TaskUpdate`, `TaskList`, `TaskGet`; `TodoWrite` in `claude -p` / Agent SDK unless `CLAUDE_CODE_ENABLE_TASKS=1` is set |
+| Background-process / subagent lifecycle (read output, cancel) | `TaskOutput`, `TaskStop` — these are distinct from the todo tools above and apply to running shells, agents, and remote sessions |
+
+## Instructions file
+
+When a skill mentions "your instructions file", on Claude Code this is **`CLAUDE.md`**. Claude Code walks up the directory tree from the current working directory and concatenates every `CLAUDE.md` and `CLAUDE.local.md` it finds along the way. Standard locations:
+
+| Scope | Location |
+|-------|----------|
+| Project (team-shared) | `./CLAUDE.md` or `./.claude/CLAUDE.md` |
+| User global | `~/.claude/CLAUDE.md` |
+| Local-private (gitignored) | `./CLAUDE.local.md` |
+| Managed policy (org-wide) | `/Library/Application Support/ClaudeCode/CLAUDE.md` (macOS), `/etc/claude-code/CLAUDE.md` (Linux/WSL), `C:\Program Files\ClaudeCode\CLAUDE.md` (Windows) |
+
+CLAUDE.md files can pull in additional content with `@path/to/file` imports (relative or absolute, max five hops deep). Subdirectory `CLAUDE.md` files are also discovered automatically and loaded on-demand when Claude Code reads files in those subdirectories.
+
+Claude Code does **not** read `AGENTS.md` directly. If a project already maintains `AGENTS.md` for other agents, import it from `CLAUDE.md` so both runtimes share the same instructions:
+
+```markdown
+@AGENTS.md
+
+## Claude Code
+
+(Claude-Code-specific instructions go here.)
+```
+
+For path-scoped rules and larger-project organization, see `.claude/rules/` (rules can be scoped to specific files via `paths` frontmatter and load on demand).
+
+## Personal skills directory
+
+User-level skills live at **`~/.claude/skills/`**. Each skill is a subdirectory containing a `SKILL.md` (with `name` and `description` frontmatter) plus any supporting files. Claude Code does not currently recognize the cross-runtime `~/.agents/skills/` path that Codex, Copilot CLI, and Gemini CLI read; if you're relying on cross-runtime support in the future, verify against the [official skills docs](https://code.claude.com/docs/en/skills).

 # Codex Tool Mapping

-| `Skill` tool (invoke a skill) | Skills load natively — just follow the instructions |

-| `Bash` (run commands) | Use your native shell tools |
+| Action skills request | Codex equivalent |
+|----------------------|------------------|
+| Read a file | `shell` (e.g., `cat`, `head`, `tail`) — Codex reads files via shell |
+| Create / edit / delete a file | `apply_patch` (structured diff for create, update, delete) |
+| Run a shell command | `shell` |
+| Search file contents | `shell` (e.g., `grep`, `rg`) |
+| Find files by name | `shell` (e.g., `find`, `ls`) |
+| Fetch a URL | `shell` with `curl` / `wget` — Codex has no native fetch tool |
+| Search the web | `web_search` (enabled by default; configurable in `config.toml` via the top-level `web_search` setting — `live`, `cached`, or `disabled`) |
+| Invoke a skill | Skills load natively — just follow the instructions |
+| Dispatch a subagent (`Subagent (general-purpose):` template) | `spawn_agent` (see [Subagent dispatch requires multi-agent support](#subagent-dispatch-requires-multi-agent-support)) |
+| Multiple parallel dispatches | Multiple `spawn_agent` calls in one response |
+| Wait for subagent result | `wait_agent` |
+| Free up subagent slot when done | `close_agent` |
+| Task tracking ("create a todo", "mark complete") | `update_plan` |
+
+## Instructions file
+
+When a skill mentions "your instructions file", on Codex this is **`AGENTS.md`** at the project root. Codex also reads `~/.codex/AGENTS.md` for global context, and an `AGENTS.override.md` (in the project tree or `~/.codex/`) takes precedence when present. Codex walks from the project root down to the current working directory, concatenating `AGENTS.md` files it finds along the way, up to `project_doc_max_bytes` (32 KiB by default).
+
+## Personal skills directory
+
+User-level skills live at **`$CODEX_HOME/skills/`** (default `~/.codex/skills/`). Codex also reads the cross-runtime path **`~/.agents/skills/`** (shared with Copilot CLI and Gemini CLI). When both directories exist at the same scope, Codex loads them both as separate skill catalogs — Codex's docs don't currently document a precedence between them. Each skill is a subdirectory containing a `SKILL.md` (with `name` and `description` frontmatter).

+| Task tracking ("create a todo", "mark complete") | `write_todos` (statuses: pending, in_progress, completed, cancelled, blocked) |
+
+## Instructions file
+
+When a skill mentions "your instructions file", on Gemini CLI this is **`GEMINI.md`**. Gemini CLI loads `GEMINI.md` hierarchically: global at `~/.gemini/GEMINI.md`, project-level files in workspace directories and their ancestors, and sub-directory `GEMINI.md` files when a tool accesses files in those directories.
+
+## Personal skills directory
+
+User-level skills live at **`~/.gemini/skills/`**, with **`~/.agents/skills/`** as a cross-runtime alias (shared with Codex and Copilot CLI). When both directories exist at the same scope, `.agents/skills/` takes precedence. Each skill is a subdirectory containing a `SKILL.md` (with `name` and `description` frontmatter).
 
 ## Subagent support
 
-Gemini CLI supports subagents natively via the `@` syntax. Use the built-in `@generalist` agent to dispatch any task — it has access to all tools and follows the prompt you provide.
+Gemini CLI dispatches subagents through the `invoke_agent` tool, which takes `agent_name` and `prompt` parameters. The same dispatch is also surfaced as a chat-syntax shortcut: typing `@generalist <prompt>` is equivalent to calling `invoke_agent` with `agent_name: "generalist"`. Built-in agent names include `generalist`, `cli_help`, `codebase_investigator`, and (with browser tooling enabled) `browser_agent`.
 
-When a skill says to dispatch a named agent type, use `@generalist` with the full prompt from the skill's prompt template:
+Skills dispatch with `Subagent (general-purpose):` and either reference a prompt-template file (e.g., `superpowers:subagent-driven-development`'s `./implementer-prompt.md`) or supply an inline prompt. On Gemini CLI:
 
-| Skill instruction | Gemini CLI equivalent |
-|-------------------|----------------------|
-| `Task tool (superpowers:implementer)` | `@generalist` with the filled `implementer-prompt.md` template |
-| `Task tool (superpowers:spec-reviewer)` | `@generalist` with the filled `spec-reviewer-prompt.md` template |
-| `Task tool (superpowers:code-reviewer)` | `@code-reviewer` (bundled agent) or `@generalist` with the filled review prompt |
-| `Task tool (superpowers:code-quality-reviewer)` | `@generalist` with the filled `code-quality-reviewer-prompt.md` template |
-| `Task tool (general-purpose)` with inline prompt | `@generalist` with your inline prompt |
+| Skill dispatch form | Gemini CLI equivalent |
+|---------------------|----------------------|
+| References a `*-prompt.md` template (implementer, spec-reviewer, code-quality-reviewer, code-reviewer, etc.) | Fill the template, then `invoke_agent` with `agent_name: "generalist"` and the filled prompt |
+| References `superpowers:requesting-code-review`'s `./code-reviewer.md` | `invoke_agent` with `agent_name: "generalist"` and the filled review template |
+| Inline prompt (no template referenced) | `invoke_agent` with `agent_name: "generalist"` and your inline prompt |
 
 ### Prompt filling
 
-Skills provide prompt templates with placeholders like `{WHAT_WAS_IMPLEMENTED}` or `[FULL TEXT of task]`. Fill all placeholders and pass the complete prompt as the message to `@generalist`. The prompt template itself contains the agent's role, review criteria, and expected output format — `@generalist` will follow it.

The prompt template itself contains the agent's role, review criteria, and expected output format — the subagent will follow it.
 
 ### Parallel dispatch
 
-Gemini CLI supports parallel subagent dispatch. When a skill asks you to dispatch multiple independent subagent tasks in parallel, request all of those `@generalist` or named subagent tasks together in the same prompt. Keep dependent tasks sequential, but do not serialize independent subagent tasks just to preserve a simpler history.

+# Pi Tool Mapping

+
+| Action skills request | Pi equivalent |
+| --- | --- |
+| Invoke a skill | Pi native skills: load the relevant `SKILL.md` with `read`, or let the human use `/skill:name` |

+| Task tracking ("create a todo", "mark complete") | Use an installed todo/task tool if available, otherwise track tasks in the plan or `TODO.md` |
+
+## Skills
+
+Pi discovers skills from configured skill directories and installed Pi packages. A Superpowers Pi package should expose `skills/` through its `pi.skills` manifest entry. Pi does not expose Claude Code's `Skill` tool, but the agent should still follow the Superpowers rule: when a skill applies, load and follow it before responding.
+
+## Subagents
+
+Pi core does not ship a standard subagent tool. The `pi-subagents` package is a strong optional companion and provides a `subagent` tool with single-agent, chain, parallel, async, forked-context, and resume/status workflows. If no subagent tool is available, do not fabricate `Task` calls; execute sequentially in the current session or explain that the optional subagent capability is not installed.
+
+## Task lists
+
+Pi core does not ship a standard task-list tool. If a todo/task extension is installed, use its documented tool. Otherwise use Superpowers plan files, checklists in Markdown, or a repo-local `TODO.md` for task tracking. Older Superpowers docs may refer to `TodoWrite`; treat that as the task-tracking action above.

 * Other Skills' metadata

-Not every token in your Skill has an immediate cost. At startup, only the metadata (name and description) from all Skills is pre-loaded. Claude reads SKILL.md only when the Skill becomes relevant, and reads additional files only as needed. However, being concise in SKILL.md still matters: once Claude loads it, every token competes with conversation history and other context.
