* feat(#3464): widen no-source-grep to detect regex.exec() on tracked text Adds an execCall kind alongside the existing regexTest detection -- regex.exec(tracked) was invisible to the rule while regex.test(tracked) was already caught, despite both reading a source-derived string through a regex. Measured: 4 previously-invisible sites across 2 files. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#3464): migrate 4 sites newly flagged by the exec() widening docs-hooks-table-parity.test.cjs's three regex-extraction loops are site-scoped marked (source-text-is-the-product) -- the dynamic preToolEvent/postToolEvent dialect branching they mirror is explicitly documented as not statically parseable, so a literal-pattern mirror is the practical minimum-cost check. no-bare-gsd-tools-command-position.test.cjs's readRouterVerbs() now requires HOST_COMMAND_ROUTERS directly instead of regex-walking gsd-tools.cjs's source text -- the same accessor three other suites already use. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3464): pay down 6 grandfathered uncited allow-test-rule markers Two were genuinely load-bearing (suppressing a real detected violation) and just needed a citation added -- phase6-capstone-conformance.test.cjs, runtime-name-policy.test.cjs, both now (#3464). Four were dead-weight file-header markers suppressing nothing -- each file's real effective sites are covered by separate, already-cited markers elsewhere in the same file. Deleted outright rather than cited, per Phase 1's own precedent (remove non-load-bearing markers instead of grandfathering them forever) -- codex-config.test.cjs (two copies), gsd-check-update-worker-platform-gate.test.cjs, orphaned-hooks.test.cjs, settings-jsonc.test.cjs. allowlist.json: 134 -> 128 entries. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#3464): re-baseline effective-exemption ceiling to 84 The exec() widening's 3 newly-marked sites are now suppressed and counted; ceiling rises 81 -> 84, the exact measured high-water mark. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3464): correct citation and restore a wrongly-deleted marker Two review corrections, both found by the orthogonal review pass: - docs-hooks-table-parity.test.cjs's 3 new exec() markers cited #3464 (mechanically "the phase that widened the rule") when the file's own established, correct reference is #3839 (the issue this whole test exists to enforce, already cited in its file header) -- fixed to match. - gsd-check-update-worker-platform-gate.test.cjs's deleted file-header marker was NOT dead weight: its codeOnly() helper wraps readFileSync and is called inline as an assert argument, a genuine source-grep pattern on real .cjs/.js source that the rule cannot currently see (helper-function indirection is a distinct blind spot from anything Phase 7/8 measured) -- CONTRIBUTING.md is explicit that "unverified" is not the same as "vestigial." Restored, site-scoped this time (directly above codeOnly(), not as an inert file-header comment) and cited (#3103, the issue the file's own docstring already references). codex-config.test.cjs's two deletions and orphaned-hooks.test.cjs's / settings-jsonc.test.cjs's deletions were independently re-verified and stand: their flagged lines read generated .toml/.json OUTPUT, not source, or have no residual pattern at all.

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, Antigravity CLI, Kimi 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, Antigravity CLI, Kimi 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:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- 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, Antigravity CLI, Kimi 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 a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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.
