Tom Boucher 67703d1586 feat(#772): adopt stable Codex hook events + commandWindows for Windows parity (#827)
* feat(#772): adopt stable Codex hook events + commandWindows for Windows parity

Register three new stable Codex hook events (SubagentStart, Stop,
PostToolUse) wired to gsd-context-monitor.js so Codex installs get
the same context-headroom tracking at subagent and session boundaries
that Claude/Qwen already have.

Add commandWindows field to the SessionStart hook entry on Windows so
Codex uses the .cmd shim directly (Git Bash/MSYS cannot POSIX-exec
node.exe). commandWindows is only emitted on win32; POSIX is unchanged.

Refactor reconcileCodexHooksJsonSessionStart into a generic
reconcileCodexHooksJsonEvent so any event name can be reconciled with
the same dedup/preserve-user-entries logic.

Add gsd-context-monitor.js and .cmd to MANAGED_HOOK_COMMAND_BASENAMES
_BY_SURFACE so idempotent re-runs de-duplicate entries correctly.

30 new tests covering: export surface, event registration for each of
the three events, commandWindows parity (POSIX vs win32), idempotency,
uninstall, and user-entry preservation.

Closes #772

* fix(#772): windows path normalization + docs-lint

- Normalize scriptPath backslashes to forward slashes in
  ensureCodexHooksJsonEvent and ensureCodexHooksJsonSessionStart so that
  isManagedHookCommand can match stored commands against configDir on
  Windows CI runners. path.resolve returns backslash paths on Windows,
  but when platform is not 'win32' (e.g. platform:'linux' in tests),
  projectManagedHookCommand skips normalization — producing a mismatch
  that breaks idempotency deduplication (the same hook entry appended
  twice on re-register). Forward-slash paths are always valid in both
  Node.js and Codex, so the normalization is safe for all platforms.
- Fix changeset pr: 0 → 827 to resolve fail_malformed_fragment.
- Add Codex hook coverage table to docs/how-to/install-on-your-runtime.md
  documenting the SubagentStart/Stop/PostToolUse events + commandWindows
  Windows-parity field added by this enhancement.

GSD Core

Git. Ship. Done.

English · Português · 简体中文 · 日本語 · 한국어

A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Gemini CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.

What is GSD Core

GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Gemini CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.


How it works

Each milestone repeats the same five-step loop, one phase at a time:

  1. Discuss — capture implementation decisions before anything is planned
  2. Plan — research, decompose, and verify the plan fits a fresh context window
  3. Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
  4. Verify — walk through what was built; diagnose and fix before declaring done
  5. Ship — create the PR, archive the phase, repeat for the next one

Quickstart

npx @opengsd/gsd-core@latest

The installer prompts for your runtime (Claude Code, OpenCode, Gemini CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.

On another runtime or without Node.js? See Install on your runtime.

Once installed, start your first project:

/gsd-new-project

Why it works

Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
