 # Installing Superpowers for Codex
 
-Quick setup to enable superpowers skills in Codex.
+Enable superpowers skills in Codex via native skill discovery. Just clone and symlink.
+
+## Prerequisites
+
+- Git
 
 ## Installation
 
-1. **Clone superpowers repository**:
+1. **Clone the superpowers repository:**
    ```bash
-   mkdir -p ~/.codex/superpowers
+   git clone https://github.com/obra/superpowers.git ~/.codex/superpowers
-   cd ~/.codex/superpowers
-   git clone https://github.com/obra/superpowers.git .
    ```
 
-2. **Create personal skills directory**:
+2. **Create the skills symlink:**
    ```bash
-   mkdir -p ~/.codex/skills
+   mkdir -p ~/.agents/skills
+   ln -s ~/.codex/superpowers/skills ~/.agents/skills/superpowers
    ```
 
-3. **Update ~/.codex/AGENTS.md** to include this superpowers section:
+   **Windows (PowerShell):**
-   ```markdown
+   ```powershell
-   ## Superpowers System
+   New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.agents\skills"
-
+   cmd /c mklink /J "$env:USERPROFILE\.agents\skills\superpowers" "$env:USERPROFILE\.codex\superpowers\skills"
-   <EXTREMELY_IMPORTANT>
-   You have superpowers. Superpowers teach you new skills and capabilities. RIGHT NOW run: `~/.codex/superpowers/.codex/superpowers-codex bootstrap` and follow the instructions it returns.
-   </EXTREMELY_IMPORTANT>
    ```
 
-## Verification
+3. **Restart Codex** (quit and relaunch the CLI) to discover the skills.
+
+## Migrating from old bootstrap
+
+If you installed superpowers before native skill discovery, you need to:
+
+1. **Update the repo:**
+   ```bash
+   cd ~/.codex/superpowers && git pull
+   ```
+
+2. **Create the skills symlink** (step 2 above) — this is the new discovery mechanism.
+
+3. **Remove the old bootstrap block** from `~/.codex/AGENTS.md` — any block referencing `superpowers-codex bootstrap` is no longer needed.
+
+4. **Restart Codex.**
+
+## Verify
 
-Test the installation:
 ```bash
-~/.codex/superpowers/.codex/superpowers-codex bootstrap
+ls -la ~/.agents/skills/superpowers
 ```
 
-You should see skill listings and bootstrap instructions. The system is now ready for use.
+You should see a symlink (or junction on Windows) pointing to your superpowers skills directory.
+
+## Updating
+
+```bash
+cd ~/.codex/superpowers && git pull
+```
+
+Skills update instantly through the symlink.
+
+## Uninstalling
+
+```bash
+rm ~/.agents/skills/superpowers
+```
+
+Optionally delete the clone: `rm -rf ~/.codex/superpowers`.

-# Superpowers Bootstrap for Codex
-
-<EXTREMELY_IMPORTANT>
-You have superpowers.
-
-**Tool for running skills:**
-- `~/.codex/superpowers/.codex/superpowers-codex use-skill <skill-name>`
-
-**Tool Mapping for Codex:**
-When skills reference tools you don't have, substitute your equivalent tools:
-- `TodoWrite` → `update_plan` (your planning/task tracking tool)
-- `Task` tool with subagents → Tell the user that subagents aren't available in Codex yet and you'll do the work the subagent would do
-- `Skill` tool → `~/.codex/superpowers/.codex/superpowers-codex use-skill` command (already available)
-- `Read`, `Write`, `Edit`, `Bash` → Use your native tools with similar functions
-
-**Skills naming:**
-- Superpowers skills: `superpowers:skill-name` (from ~/.codex/superpowers/skills/)
-- Personal skills: `skill-name` (from ~/.codex/skills/)
-- Personal skills override superpowers skills when names match
-
-**Critical Rules:**
-- Before ANY task, review the skills list (shown below)
-- If a relevant skill exists, you MUST use `~/.codex/superpowers/.codex/superpowers-codex use-skill` to load it
-- Announce: "I've read the [Skill Name] skill and I'm using it to [purpose]"
-- Skills with checklists require `update_plan` todos for each item
-- NEVER skip mandatory workflows (brainstorming before coding, TDD, systematic debugging)
-
-**Skills location:**
-- Superpowers skills: ~/.codex/superpowers/skills/
-- Personal skills: ~/.codex/skills/ (override superpowers when names match)

 # Superpowers Release Notes
 
+## v4.3.1 (2026-02-21)
+
+### Added
+
+**Cursor support**
+
+Superpowers now works with Cursor's plugin system. Includes a `.cursor-plugin/plugin.json` manifest and Cursor-specific installation instructions in the README. The SessionStart hook output now includes an `additional_context` field alongside the existing `hookSpecificOutput.additionalContext` for Cursor hook compatibility.
+
+### Fixed
+
+**Windows: Restored polyglot wrapper for reliable hook execution (#518, #504, #491, #487, #466, #440)**
+
+Claude Code's `.sh` auto-detection on Windows was prepending `bash` to the hook command, breaking execution. The fix:
+
+- Renamed `session-start.sh` to `session-start` (extensionless) so auto-detection doesn't interfere
+- Restored `run-hook.cmd` polyglot wrapper with multi-location bash discovery (standard Git for Windows paths, then PATH fallback)
+- Exits silently if no bash is found rather than erroring
+- On Unix, the wrapper runs the script directly via `exec bash`
+- Uses POSIX-safe `dirname "$0"` path resolution (works on dash/sh, not just bash)
+
+This fixes SessionStart failures on Windows with spaces in paths, missing WSL, `set -euo pipefail` fragility on MSYS, and backslash mangling.
+
+## v4.3.0 (2026-02-12)
+
+This fix should dramatically improve superpowers skills compliance and should reduce the chances of Claude entering its native plan mode unintentionally.
+
+### Changed
+
+**Brainstorming skill now enforces its workflow instead of describing it**
+
+Models were skipping the design phase and jumping straight to implementation skills like frontend-design, or collapsing the entire brainstorming process into a single text block. The skill now uses hard gates, a mandatory checklist, and a graphviz process flow to enforce compliance:
+
+- `<HARD-GATE>`: no implementation skills, code, or scaffolding until design is presented and user approves
+- Explicit checklist (6 items) that must be created as tasks and completed in order
+- Graphviz process flow with `writing-plans` as the only valid terminal state
+- Anti-pattern callout for "this is too simple to need a design" — the exact rationalization models use to skip the process
+- Design section sizing based on section complexity, not project complexity
+
+**Using-superpowers workflow graph intercepts EnterPlanMode**
+
+Added an `EnterPlanMode` intercept to the skill flow graph. When the model is about to enter Claude's native plan mode, it checks whether brainstorming has happened and routes through the brainstorming skill instead. Plan mode is never entered.
+
+### Fixed
+
+**SessionStart hook now runs synchronously**
+
+Changed `async: true` to `async: false` in hooks.json. When async, the hook could fail to complete before the model's first turn, meaning using-superpowers instructions weren't in context for the first message.
+
+## v4.2.0 (2026-02-05)
+
+### Breaking Changes
+
+**Codex: Replaced bootstrap CLI with native skill discovery**
+
+The `superpowers-codex` bootstrap CLI, Windows `.cmd` wrapper, and related bootstrap content file have been removed. Codex now uses native skill discovery via `~/.agents/skills/superpowers/` symlink, so the old `use_skill`/`find_skills` CLI tools are no longer needed.
+
+Installation is now just clone + symlink (documented in INSTALL.md). No Node.js dependency required. The old `~/.codex/skills/` path is deprecated.
+
+### Fixes
+
+**Windows: Fixed Claude Code 2.1.x hook execution (#331)**
+
+Claude Code 2.1.x changed how hooks execute on Windows: it now auto-detects `.sh` files in commands and prepends `bash`. This broke the polyglot wrapper pattern because `bash "run-hook.cmd" session-start.sh` tries to execute the `.cmd` file as a bash script.
+
+Fix: hooks.json now calls session-start.sh directly. Claude Code 2.1.x handles the bash invocation automatically. Also added .gitattributes to enforce LF line endings for shell scripts (fixes CRLF issues on Windows checkout).
+
+**Windows: SessionStart hook runs async to prevent terminal freeze (#404, #413, #414, #419)**
+
+The synchronous SessionStart hook blocked the TUI from entering raw mode on Windows, freezing all keyboard input. Running the hook async prevents the freeze while still injecting superpowers context.
+
+**Windows: Fixed O(n^2) `escape_for_json` performance**
+
+The character-by-character loop using `${input:$i:1}` was O(n^2) in bash due to substring copy overhead. On Windows Git Bash this took 60+ seconds. Replaced with bash parameter substitution (`${s//old/new}`) which runs each pattern as a single C-level pass — 7x faster on macOS, dramatically faster on Windows.
+
+**Codex: Fixed Windows/PowerShell invocation (#285, #243)**
+
+- Windows doesn't respect shebangs, so directly invoking the extensionless `superpowers-codex` script triggered an "Open with" dialog. All invocations now prefixed with `node`.
+- Fixed `~/` path expansion on Windows — PowerShell doesn't expand `~` when passed as an argument to `node`. Changed to `$HOME` which expands correctly in both bash and PowerShell.
+
+**Codex: Fixed path resolution in installer**
+
+Used `fileURLToPath()` instead of manual URL pathname parsing to correctly handle paths with spaces and special characters on all platforms.
+
+**Codex: Fixed stale skills path in writing-skills**
+
+Updated `~/.codex/skills/` reference (deprecated) to `~/.agents/skills/` for native discovery.
+
+### Improvements
+
+**Worktree isolation now required before implementation**
+
+Added `using-git-worktrees` as a required skill for both `subagent-driven-development` and `executing-plans`. Implementation workflows now explicitly require setting up an isolated worktree before starting work, preventing accidental work directly on main.
+
+**Main branch protection softened to require explicit consent**
+
+Instead of prohibiting main branch work entirely, the skills now allow it with explicit user consent. More flexible while still ensuring users are aware of the implications.
+
+**Simplified installation verification**
+
+Removed `/help` command check and specific slash command list from verification steps. Skills are primarily invoked by describing what you want to do, not by running specific commands.
+
+**Codex: Clarified subagent tool mapping in bootstrap**
+
+Improved documentation of how Codex tools map to Claude Code equivalents for subagent workflows.
+

 ### Prerequisites
 
-- OpenAI Codex access
+- OpenAI Codex CLI
-- Shell access to install files
+- Git
 
-### Installation Steps
+### Steps
 
-#### 1. Clone Superpowers
+1. Clone the repo:
+   ```bash
+   git clone https://github.com/obra/superpowers.git ~/.codex/superpowers
+   ```
 
-```bash
+2. Create the skills symlink:
-mkdir -p ~/.codex/superpowers
+   ```bash
-git clone https://github.com/obra/superpowers.git ~/.codex/superpowers
+   mkdir -p ~/.agents/skills
+   ln -s ~/.codex/superpowers/skills ~/.agents/skills/superpowers
+   ```
+
+3. Restart Codex.
+
+### Windows
+
+Use a junction instead of a symlink (works without Developer Mode):
+
+```powershell
+New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.agents\skills"
+cmd /c mklink /J "$env:USERPROFILE\.agents\skills\superpowers" "$env:USERPROFILE\.codex\superpowers\skills"
 ```
 
-#### 2. Install Bootstrap
+## How It Works
 
-The bootstrap file is included in the repository at `.codex/superpowers-bootstrap.md`. Codex will automatically use it from the cloned location.
+Codex has native skill discovery — it scans `~/.agents/skills/` at startup, parses SKILL.md frontmatter, and loads skills on demand. Superpowers skills are made visible through a single symlink:
-
-#### 3. Verify Installation
-
-Tell Codex:
 
 ```
-Run ~/.codex/superpowers/.codex/superpowers-codex find-skills to show available skills
+~/.agents/skills/superpowers/ → ~/.codex/superpowers/skills/
 ```
 
-You should see a list of available skills with descriptions.
+The `using-superpowers` skill is discovered automatically and enforces skill usage discipline — no additional configuration needed.
 
 ## Usage
 
-### Finding Skills
+Skills are discovered automatically. Codex activates them when:
-
+- You mention a skill by name (e.g., "use brainstorming")
-```
+- The task matches a skill's description
-Run ~/.codex/superpowers/.codex/superpowers-codex find-skills
+- The `using-superpowers` skill directs Codex to use one
-```
-
-### Loading a Skill
-
-```
-Run ~/.codex/superpowers/.codex/superpowers-codex use-skill superpowers:brainstorming
-```
-
-### Bootstrap All Skills
-
-```
-Run ~/.codex/superpowers/.codex/superpowers-codex bootstrap
-```
-
-This loads the complete bootstrap with all skill information.

-
-## Architecture
-
-### Codex CLI Tool
-
-**Location:** `~/.codex/superpowers/.codex/superpowers-codex`
-
-A Node.js CLI script that provides three commands:
-- `bootstrap` - Load complete bootstrap with all skills
-- `use-skill <name>` - Load a specific skill
-- `find-skills` - List all available skills
-
-### Shared Core Module
-
-**Location:** `~/.codex/superpowers/lib/skills-core.js`
-
-The Codex implementation uses the shared `skills-core` module (ES module format) for skill discovery and parsing. This is the same module used by the OpenCode plugin, ensuring consistent behavior across platforms.
-
-### Tool Mapping
-
-Skills written for Claude Code are adapted for Codex with these mappings:
-
-- `TodoWrite` → `update_plan`
-- `Task` with subagents → Tell user subagents aren't available, do work directly
-- `Skill` tool → `~/.codex/superpowers/.codex/superpowers-codex use-skill`
-- File operations → Native Codex tools
 
 ## Updating
 
 ```bash
-cd ~/.codex/superpowers
+cd ~/.codex/superpowers && git pull
-git pull
 ```
 
+Skills update instantly through the symlink.
+
+## Uninstalling
+
+```bash
+rm ~/.agents/skills/superpowers
+```
+
+**Windows (PowerShell):**
+```powershell
+Remove-Item "$env:USERPROFILE\.agents\skills\superpowers"
+```
+
+Optionally delete the clone: `rm -rf ~/.codex/superpowers` (Windows: `Remove-Item -Recurse -Force "$env:USERPROFILE\.codex\superpowers"`).
+
 ## Troubleshooting
 
-### Skills not found
+### Skills not showing up
 
-1. Verify installation: `ls ~/.codex/superpowers/skills`
+1. Verify the symlink: `ls -la ~/.agents/skills/superpowers`
-2. Check CLI works: `~/.codex/superpowers/.codex/superpowers-codex find-skills`
+2. Check skills exist: `ls ~/.codex/superpowers/skills`
-3. Verify skills have SKILL.md files
+3. Restart Codex — skills are discovered at startup
 
-### CLI script not executable
+### Windows junction issues
 
-```bash
+Junctions normally work without special permissions. If creation fails, try running PowerShell as administrator.
-chmod +x ~/.codex/superpowers/.codex/superpowers-codex
-```
-
-### Node.js errors
-
-The CLI script requires Node.js. Verify:
-
-```bash
-node --version
-```
-
-Should show v14 or higher (v18+ recommended for ES module support).

-REM DEPRECATED: This polyglot wrapper is no longer used as of Claude Code 2.1.x
+REM On Windows: cmd.exe runs the batch portion, which finds and calls bash.
-REM ============================================================================
+REM On Unix: the shell interprets this as a script (: is a no-op in bash).
 REM
-REM Claude Code 2.1.x changed the Windows execution model for hooks:
+REM Hook scripts use extensionless filenames (e.g. "session-start" not
+REM "session-start.sh") so Claude Code's Windows auto-detection -- which
+REM prepends "bash" to any command containing .sh -- doesn't interfere.
 REM
-REM   Before (2.0.x): Hooks ran with shell:true, using the system default shell.
-REM                   This wrapper provided cross-platform compatibility by
-REM                   being both a valid .cmd file (Windows) and bash script.
-REM
-REM   After (2.1.x):  Claude Code now auto-detects .sh files in hook commands
-REM                   and prepends "bash " on Windows. This broke the wrapper
-REM                   because the command:
-REM                     "run-hook.cmd" session-start.sh
-REM                   became:
-REM                     bash "run-hook.cmd" session-start.sh
-REM                   ...and bash cannot execute a .cmd file.
-REM
-REM The fix: hooks.json now calls session-start.sh directly. Claude Code 2.1.x
-REM handles the bash invocation automatically on Windows.

+## Anti-Pattern: "This Is Too Simple To Need A Design"
+
+Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.

+2. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
+3. **Propose 2-3 approaches** — with trade-offs and your recommendation
+4. **Present design** — in sections scaled to their complexity, get user approval after each section
+5. **Write design doc** — save to `docs/plans/YYYY-MM-DD-<topic>-design.md` and commit
