* test(#3211): failing-first coverage for the issue-link follow-up exemption Adds the regression suite before the policy module exists, so the RED state is recorded against a real verdict rather than asserted. Covers the reported gap (a fork test-only follow-up PR cannot satisfy the gate without an inert closing keyword) and the file-list truncation vector that any diff-shape exemption must fail closed on. Refs #3211 * chore(#3211): accept a non-closing issue reference for docs/test-only PRs The `Issue link required` gate modelled exactly one PR->issue relationship — "this PR closes that issue" — and its sole exemption additionally required same-repo identity (#1389), so a fork PR had no exemption path of any kind. A test-only or docs-only follow-up therefore had to ship a knowingly-inert `Closes #<already-closed-issue>` to get a green check. The verdict now lives in scripts/require-issue-link-policy.cjs as a pure, unit-tested function returning a typed reason. It additionally accepts a non-closing reference (`Refs #N`, `Follow-up to #N`, ...) but only when every changed file is under tests/, under docs/, or is a root-level *.md — the same doc-only shape pre-pr-gate.sh:111 recognizes, minus CHANGELOG.md, which changeset/lint.cjs classes as user-facing. Source-touching PRs still require a closing keyword and a PR with no reference at all still hard-fails, so gate strength is unchanged. Both constraints the issue names as hard requirements are preserved: the backmerge exemption keeps its same-repo conjunct, and the failing step's `if:` stays step-level so the required check reports SUCCESS rather than a branch-protection-blocking `skipped`. Also closes a forgery vector found while building this. `gh pr view --json files` returns at most 100 paths and does not paginate, while the payload's `changed_files` reports the true total (verified live: PR #3202 returns 100 of 118). A >100-file PR could therefore present a falsely tests-only list. The new shared helper scripts/lib/pr-changed-files.cjs fails closed when the list cannot be confirmed complete, and the pre-existing tooling-paths carve-out in scripts/pr-template-policy.cjs — which relaxed template enforcement on the same untrustworthy list — now uses it too. Closes #3211 * fix(#3211): treat the authoritative file count as authority at every list size Both orthogonal review passes independently found the same blocker. `fileListIsComplete` only compared the list length against the PR's true `changed_files` count once the list reached the 100-entry page cap, so any mechanism that shortened the list BELOW the cap went undetected: evaluateIssueLink({prBody:"Refs #1", sameRepo:false, changedFiles:["CONTRIBUTING.md"], changedFilesTotal:3}) -> {ok:true, reason:"ok_followup_reference"} The concrete exploit was a $GITHUB_OUTPUT heredoc collision. Both this workflow and pr-template-format.yml wrote the file list with a fixed terminator (`GSD_EOF` / the even weaker `EOF`), and every path in that value is attacker-controlled on a fork PR. A file named after the delimiter closes the value early and drops every path after it, so a fork PR touching src/ could present a list of only its exempt-looking files and take the follow-up exemption. That is exactly the #1389 property this change is required to preserve. Fixed in two independent layers: 1. The total is now the authority at every size, not only at/above the cap. One rule catches truncation, delimiter collision, and a path containing a newline, without having to enumerate the mechanisms. 2. Both workflows now use an unguessable random delimiter, per GitHub's documented guidance for untrusted multiline output. Also from review: pr-template-format.yml never passed CHANGED_FILES_TOTAL, so the parameter threaded through evaluatePrTemplate was always undefined in production and would have permanently blocked the tooling carve-out for any 100+-file PR; its env is now wired. Root-doc exclusion is case-insensitive. Dropped a no-op `tr '\n' '\n'`. Refs #3211 * chore(#3211): regenerate install-tree fixtures for the new shared helper scripts/lib/** ships in the install tree, so adding scripts/lib/pr-changed-files.cjs drifts all 19 golden fixtures by exactly one path each. Caught by tests/golden-install-tree.test.cjs (25 failures on the remote runner), which is the drift detector doing its job — not a defect. Placement is deliberate: every existing occupant of scripts/lib/ is a CI/dev helper that already ships (alias-drift-families, allowlist-ratchet, cli-exit, drift-scan), so a shared helper used by two policy scripts belongs there. The two policy modules themselves live at the top level of scripts/ and do not ship. Regenerated with `npm run gen:install-tree`; the delta is one added path per fixture and nothing else. Refs #3211 * fix(#3211): keep the shared CI helper out of the shipped install tree The remote runner reported 6 failures on the previous head. Two causes. `scripts/lib/**` is enumerated in `bin/install.js` (GSD_SCRIPTS_LIB_FILES) and ships to users, and the install suite asserts that enumeration is complete. Putting the new shared helper there broke four install tests and drifted all 19 golden install-tree fixtures. The right answer is not to add it to the manifest — it is CI-only tooling used by two scripts that do not ship, so it has no business in a user's config directory. Moved to `scripts/pr-changed-files.cjs`; top-level `scripts/` ships only what the installer names explicitly, so nothing is enumerated and nothing ships. The fixture regeneration from the previous commit is reverted: the install-tree fixtures are byte-identical to `next` again, and `bin/` is untouched. That also keeps the diff free of any user-facing path, so no changeset fragment is required. The other failure was a stale test, not a regression. The workflow carve-out suite asserted the backmerge exemption by grepping require-issue-link.yml for `startsWith(github.head_ref, ...)` and `steps.check.outputs.found`. This change moved the whole verdict — carve-out included — into the policy module and renamed the step, so those assertions measured a location the logic no longer occupies. Rewritten to lock the property at its new home, and made stronger in the process: the step-level placement is now verified by PARSING the YAML and asserting the job carries no `if:` of its own (a job-level `if:` would make the required check report `skipped` and block branch protection), and the #1389 anti-forgery conjunct is asserted BEHAVIORALLY against evaluateIssueLink for both sameRepo branches rather than by matching text. The bootstrap fallback grep is locked too, so the introducing-PR path cannot be silently dropped. Refs #3211 * fix(#3211): correct the contributor guidance and pin it against the rule The sticky comment the gate posts still described the qualifying diff shape as "nothing outside tests/ and docs/". The predicate had since been widened to also accept root-level *.md, so the guidance was narrower than the rule it describes — and narrower in the worst direction: a contributor whose PR is CONTRIBUTING.md plus a test, which is exactly the shape #3211 was filed about, would have been told they do not qualify while the gate was in fact passing them. The two failure explanations now name all three accepted shapes and the CHANGELOG.md exclusion. This is a shared-rule-across-parallel-surfaces drift: the guidance restates a rule whose definition lives in EXEMPT_PATH_PREFIXES / isRootLevelDoc / EXCLUDED_ROOT_DOCS. It was caught by eye, which is not a control. Added the parity assertion CLAUDE.md prescribes for exactly this: the test parses the workflow, pulls the github-script body out of the failing step, and asserts it names every entry of EXEMPT_PATH_PREFIXES and every entry of EXCLUDED_ROOT_DOCS — derived from the module's exports, never from a second hardcoded copy — plus the root-level shape and an actionable `Refs #` example. The test is non-vacuous by construction and by demonstration: it guards against zero-length iteration and an empty script body, and removing any single expected token from the real text makes it fail (verified per token, plus the empty-string case which reports all five missing).

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

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.
