* test(#2315): regression test for review.default_reviewers precedence A bare /gsd-plan-review-convergence invocation (no reviewer flags) is supposed to let users configure a persistent reviewer lineup via review.default_reviewers and just run the loop. Instead, the orchestrator's argument parser silently discards that configuration and forces --codex on every no-flag invocation — with no warning that the configured reviewers were ignored. This commit adds a regression test that fails against the pre-fix workflow (the buggy unconditional --codex fallback is still present at this commit) and passes after the fix lands: - Structural: the workflow must NOT contain an unconditional 'if [ -z "$REVIEWER_FLAGS" ]; then REVIEWER_FLAGS="--codex"; fi' line before the workflow.plan_review_convergence config gate. - Structural: the workflow must query review.default_reviewers AFTER the config gate and document that empty REVIEWER_FLAGS lets gsd-review apply the default. - Behavioral: matrix across {configured, unset, empty-array, explicit-flag} invoking the actual deployed parse + resolution blocks with a stubbed gsd_run. Also updates two existing tests whose assertions the fix makes stale: - #2293 behavioral: endMarker was the buggy unconditional fallback line; the bare invocation assertion was 'run("5") === "--codex"'. Both flip post-fix (endMarker is now the last --all grep line; bare invocation returns empty from the parse block, default applied later in step 1.5). - command-default-claim: the pre-fix command documented '--codex (default if no reviewer specified)' which was the user-facing mirror of the bug. The assertion now requires the command to document the review.default_reviewers precedence. * fix(#2315): respect review.default_reviewers in bare convergence invocation Root cause: plan-review-convergence.md step 1 (Parse and Normalize Arguments) contained an unconditional fallback that set REVIEWER_FLAGS=\"--codex\" whenever no explicit reviewer flag was supplied. This value was then interpolated verbatim into the gsd-review args, so gsd-review saw --codex as an explicit flag (precedence rule 1) and never reached rule 3 (review.default_reviewers). The same path silently dropped any configured review.reviewer_instances (instances participate ONLY via review.default_reviewers per ADR-1517). Fix: - Remove the unconditional --codex fallback from step 1. - Add a config-gated resolution in step 1.5 (after CONVERGENCE_ENABLED check) that queries review.default_reviewers and either leaves REVIEWER_FLAGS empty (letting gsd-review apply its own rule-3 default) or falls back to --codex when no default is configured — preserving the pre-fix default for unconfigured users (AC3). - Replace the banner {REVIEWER_FLAGS} token with {REVIEWER_DISPLAY} so the startup banner reflects what will actually run (AC4), not a hardcoded value. The fix upholds the documented precedence contract (ADR-0011, ADR-0015) that the bug was actively violating. Explicit-flag invocations (--gemini, --all, etc.) are unaffected (AC5). References: #2315; ADR-0011 (review.default_reviewers precedence); ADR-0015 (autonomous cross-AI convergence); ADR-1517 (reviewer instances). * chore(#2315): bump plan-review-convergence.md baseline + changeset - Bump plan-review-convergence.md size baseline 23713 → 25536 (the new step-1.5 default-resolution block). - Add .changeset/plucky-yaks-roar.md documenting the user-visible change. * fix(#2315): restore /gsd: colon syntax + skip behavioral test when jq missing Two follow-ups to the #2315 fix discovered by gsd-test: 1. The fix commit accidentally regressed the slash-command namespace in the disabled-feature exit message: /gsd:plan-review-convergence (correct, from PR #3452) became /gsd-plan-review-convergence (retired dash syntax). The slash-command-namespace invariant test caught this. Restored the colon form. 2. The behavioral test exercises the deployed reviewer-resolution block, which pipes through jq. jq is a documented production dependency (review.md:244 "install jq if missing") and is present in every production deployment, but is NOT on PATH in the gsd-test linux-node{22,24} containers (same constraint as tests/opencode-review-reconstruction. property.test.cjs). Without jq, the printf|jq pipeline fails silently, the ||echo 0 fallback yields DEFAULT_REVIEWERS_COUNT=0, and the resolution falls through to the --codex branch — producing a false negative. Added a jqAvailable guard at module load (matching the existing pattern) and skip the behavioral test when jq is absent. The structural tests (no bash execution) still run and validate the fix. * chore(#2315): regenerate golden-install-parity fixtures Source changes to plan-review-convergence.md (workflow + skill mirror + command doc) changed the install-tree hashes. Regenerated via 'npm run gen:golden' after rebuilding gsd-core/bin/lib/install-engine.cjs ('npm run build:lib') — the on-disk lib was stale relative to src/install-engine.cts (isSymlinkedDestOptIn) and blocked fixture gen. * test(#2315): address review findings — strengthen structural tests + property test Code-review + security-review (isolated subagent passes) surfaced Low/Nit findings; this commit addresses the test-side findings: - Structural test 1 ("unconditional --codex one-liner") now asserts the buggy line is absent EVERYWHERE, not just before the config gate. The earlier assertion allowed a maintainer to re-add the line after the gate (passing the structural test) while the bug would still bite at runtime before the gate runs. - Structural test 4 ("banner uses REVIEWER_DISPLAY") now asserts the LITERAL banner placeholder "Reviewers: {REVIEWER_DISPLAY}" and forbids "Reviewers: {REVIEWER_FLAGS}". The earlier workflow.includes( "REVIEWER_DISPLAY") was satisfied by a comment mention. - New structural test for command/skill content parity: both files must document the review.default_reviewers precedence on the --codex flag (catches a manual edit to one that the gen:plugin-skills mirror misses). - Behavioral test stub now passes default_reviewers via env var ($GSD_TEST_DEFAULT_REVIEWERS) instead of inline-interpolating into a bash single-quoted string. Removes the (currently-safe) fragility where a future test input containing a single quote would close the bash quote and execute as bash under execFileSync. - New property test (fast-check, numRuns=25) for the JSON-classification contract: non-empty arrays of slugs -> empty REVIEWER_FLAGS; empty array / scalar JSON / malformed JSON -> --codex fallback. Locks the parser contract per CLAUDE.md mandate. * fix(#2315): address review findings — defensive jq-missing warning + banner cleanup Code-review surfaced two Low-severity workflow-side findings: - Defensive jq-missing warning: if jq is not on PATH in production (it is a documented dependency per review.md:244, but the dependency can be absent in degraded environments), the printf|jq pipeline fails silently to "0" and a user with review.default_reviewers configured gets --codex with no indication their configured default was unreadable. Added a command -v jq guard at the top of the resolution that falls back to --codex AND emits a stderr warning explaining the reason. This makes the failure diagnosable instead of silently reproducing the #2315 override. - Banner leading-space cleanup: REVIEWER_FLAGS accumulates with a leading space ("$REVIEWER_FLAGS --gemini" from ""), so the explicit-flag branch of REVIEWER_DISPLAY="$REVIEWER_FLAGS" rendered "Reviewers: --gemini" (double space). Pre-existing but worth fixing alongside the AC4 banner work. Strip one leading space with the ${VAR# } parameter expansion in the explicit-flag branch only (the configured-default and --codex branches already produce clean strings). * chore(#2315): bump plan-review-convergence.md baseline + regen golden fixtures The defensive jq-missing warning grew plan-review-convergence.md (25536 -> 26285 bytes). Bumps the per-file baseline snapshot and regenerates the golden-install-parity fixtures for the resulting install-tree hash changes. * chore(#2315): backfill pr:2451 in .changeset/plucky-yaks-roar.md
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.
