* test(#3806): add parity tests for the Review Dispositions Ledger contract Failing-first: asserts references/planner-reviews.md, workflows/plan-phase.md, and agents/gsd-plan-checker.md agree on a single canonical "Review Dispositions Ledger" heading, its round-scoping, L##@{sha} anchor format, and append-only supersession rule. These fail until the canon and its two references are added. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(#3806): canonize the Review Dispositions Ledger contract Promote the existing planner-reviews.md Step 4 return-payload tables (Review Feedback Addressed/Deferred) into a canonical `## Review Dispositions Ledger` PLAN.md section, stated once in planner-reviews.md and referenced (not restated) from plan-phase.md's <review_incorporation_contract> and gsd-plan-checker.md's Review Incorporation dimension. Adds round-scoping (`### Round {N} — {REVIEWS_sha}`), a `L##@{sha}` line-anchor format so a REVIEWS.md reference survives the file being rewritten each round, and an append-only supersession rule. Scoped to part 1 only per the maintainer's approved-feature verdict — the deterministic lint/check verb (part 2) is explicitly deferred to a follow-up. Also: ADR-3806 recording the decision, a docs/features/ fragment (FEATURES.md is generated), and a changeset fragment. Closes #3806 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3806): fenced-example count bug and lint findings from review - tests/plan-review-convergence.test.cjs: the "heading exactly once" test counted the canonical heading text globally, so it also matched the illustrative fenced-code example in planner-reviews.md that shows the same heading as sample content, always failing 2 !== 1. Rewritten as a bounded line scanner that skips fenced blocks (found by an isolated adversarial review pass). Also bounded an unbounded regex quantifier over readFileSync content flagged by local/no-unbounded-quantifier. - docs/features/review-dispositions-ledger.md: match house fragment style (bold-lead paragraphs, not #### headings) per the Standards-axis review; regenerated docs/FEATURES.md. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3806): fit reference-cite fix within size hard caps; ack growth Trims the plan-phase.md / gsd-plan-checker.md reference-cite text to a single short clause pointing at gsd-core/references/planner-reviews.md (also fixes the bare `references/planner-reviews.md` cite the #3576 shipped-reference-cites gate rejects), bringing both files back under their SIZE hard caps and the plan-phase.md phase6 shrink-only baseline. Both files still grow slightly versus origin/next, acknowledged below per ADR-2719's emitted-drift-ack contract. Emitted-Drift-Ack-Growth: gsd-plan-checker.md — adds a short pointer (in the existing Review Incorporation bullet) to the canonical Review Dispositions Ledger location (#3806); stays within the LARGE hard cap. Emitted-Drift-Ack-Growth: plan-phase.md — adds a short pointer (in the existing review_incorporation_contract bullet) to the canonical Review Dispositions Ledger location (#3806); stays under the XL hard cap and the phase6 shrink-only baseline. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3806): correct malformed Emitted-Drift-Ack-Growth trailer block The previous commit's two Emitted-Drift-Ack-Growth trailers were separated from the Co-Authored-By trailer by a blank line, so git's own trailer parser (which tests/helpers/emitted-runtime.cjs reads via `%(trailers:key=...)`) only recognized the last contiguous block (Co-Authored-By) and treated the Ack-Growth lines as ordinary body text — invisible to the emitted-attribution gate, not malformed data. Restating them here as one contiguous trailer block, git log over the PR range aggregates trailers from every commit, so this is additive. Emitted-Drift-Ack-Growth: gsd-plan-checker.md — adds a short pointer (in the existing Review Incorporation bullet) to the canonical Review Dispositions Ledger location (#3806); stays within the LARGE hard cap. Emitted-Drift-Ack-Growth: plan-phase.md — adds a short pointer (in the existing review_incorporation_contract bullet) to the canonical Review Dispositions Ledger location (#3806); stays under the XL hard cap and the phase6 shrink-only baseline. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3806): isolate the ack-trailer paragraph as its own trailer block Git's trailer parser requires the trailer paragraph to be the message's final paragraph, preceded by a blank line, and to contain nothing but trailer-shaped lines. The prior commit's blank line before the trailer lines was missing, which folded the leading Emitted-Drift-Ack-Growth lines into an ordinary prose paragraph. Emitted-Drift-Ack-Growth: gsd-plan-checker.md — adds a short pointer (in the existing Review Incorporation bullet) to the canonical Review Dispositions Ledger location (#3806); stays within the LARGE hard cap. Emitted-Drift-Ack-Growth: plan-phase.md — adds a short pointer (in the existing review_incorporation_contract bullet) to the canonical Review Dispositions Ledger location (#3806); stays under the XL hard cap and the phase6 shrink-only baseline.

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.
