* chore(#2896): convert CONTEXT.md prose defect registry into enforced gates Squashes the prior 4-commit sequence and fixes defects found while resuming this branch: 5 orphaned/corrupted DEFECT fragment lines left by an earlier botched edit, 17 "Source of truth: Memtrace `find_symbol`" placeholders that had destroyed real file-path citations, and 3 DEFECT.GENERATIVE-* entries merged into one RULESET.GENERATIVE-FIX predicate (policy, not an unenforced defect) to satisfy the zero DEFECT.<NAME>.<field>= acceptance criterion. Six mechanizable defects get real gates: DEFECT.UNBOUNDED-SUBPROCESS (eslint-rules/require-subprocess-timeout.cjs), DEFECT.CANARY-VERSION-LEAK (scripts/lint-canary-version-leak.cjs + version-gate.yml), DEFECT.CHANGESET-PR-FIELD-DRIFT (findPrFieldDrift in changeset/lint.cjs), DEFECT.FRONTMATTER-SCALAR-BROAD-GREP, DEFECT.REMOVED-BUT-NEEDED, and DEFECT.DEFAULT-FLIP-DOCUMENTATION (new lint scripts, wired into lint:ci). Already-enforced and unenforceable prose entries are deleted; the gate is the record. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2896): route the new lint tests' subprocess calls through the bounded process-seam helper The 4 new test files for this PR's lint checks called cp.spawnSync/ execFileSync directly with no timeout, tripping this repo's own existing local/no-unbounded-spawn ESLint rule. Route every one through runNode/gitOrThrow (tests/helpers/process-seam.cjs, tests/helpers/git-fixture.cjs) instead, matching the pattern already used elsewhere in the suite (e.g. tests/changeset-lint.test.cjs). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: register claude-orchestration.cjs and regenerate stale generated indexes Pre-existing drift on next, unrelated to this PR's own change, surfaced by running lint:ci as part of verifying #2896: two cli_modules (claude-orchestration.cjs, write-set.cjs) landed without a manifest regen, and CONTEXT.md's own edits in this PR staled its two generated indexes. Adds the missing docs/INVENTORY.md row for claude-orchestration.cjs (write-set.cjs already had one — only its manifest entry was stale) and regenerates docs/INVENTORY-MANIFEST.json, docs/CONTEXT-INDEX.json, and examples/dynamic-context-management/CONTEXT-INDEX.json. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2896): default-flip-documentation lint's local fallback base was main, not next Found in review: every other base-ref fallback in this repo (see scripts/changeset/lint.cjs's DEFAULT_BASE, #2988) defaults to `next`, the integration branch every PR actually targets — `main` is the release branch. This script's local fallback (used only when GITHUB_BASE_REF is unset, i.e. never in CI, but potentially on a local or direct invocation) diffed against the wrong ref. No test exercised the unset-env-var path, so it shipped unnoticed; every e2e test sets GITHUB_BASE_REF explicitly and is unaffected by this fix. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2896): stale eslint comment, overclaiming CONTEXT.md wording, and an incompletely-regenerated manifest Found by the isolated Standards code-review pass: - eslint.config.mjs's require-subprocess-timeout comment said "'warn' for now... flip to 'error' once migrated" while the rule already shipped as 'error' with all 8 sites migrated in the same commit — described a state that never existed. - The CONTEXT.md pointer block claimed the rule's bounded call sites "never throw", but roadmap-upgrade.cts's pre-mutation clean-tree check correctly still throws on failure (it gates a destructive real-run migration; degrading to "assume clean" would risk clobbering uncommitted work) — softened the claim to describe both shapes accurately instead of overclaiming one. - docs/INVENTORY-MANIFEST.json's claude-orchestration.cjs/write-set.cjs entries from the prior "fix: register claude-orchestration.cjs..." commit didn't actually land — re-running the generator now includes them; lint:generated-sync is green. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2896): backfill changeset pr field with the real PR number Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2896): normalize buildCorpus file paths to POSIX in lint-removed-but-needed Windows CI caught it: path.relative(root, abs) returns backslash- separated paths on Windows, but findSurvivingReferences's package-lock special case does file.startsWith('.github/workflows') — a forward- slash literal. On Windows the check silently never matched, so tests/removed-but-needed-lint.test.cjs's real-defect-shape fixture got exit 0 instead of the expected exit 1. Normalize at the production source (RULESET.CONTENT-PATH-NORMALIZATION) rather than the test side.

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.
