* fix(#2444): re-resolve body-parser to 2.3.0 in lockfile (GHSA-v422-hmwv-36x6) GHSA-v422-hmwv-36x6 (body-parser DoS via invalid limit value, low severity, published 2026-07-20T23:23:26Z) made tests/npm-integrity-gate.test.cjs (#3588: root workspace production tree has no advisories) fail any subsequent npm audit --omit=dev. The advisory affects body-parser >=2.0.0 <2.3.0 pulled transitively via @anthropic-ai/claude-agent-sdk -> @modelcontextprotocol/sdk -> express -> body-parser@2.2.2. express@5.2.1 already declares body-parser as ^2.2.1, so 2.3.0 is a valid re-resolution within express's own compatibility range — no override needed. Regenerated the lockfile via 'npm audit fix --omit=dev' which re-resolves transitive deps within their declared ranges; package.json is unchanged. Verified: npm audit --omit=dev reports 0/0/0/0/0 advisories; body-parser now reads as 2.3.0 in 'npm ls body-parser --omit=dev'. * test(#2450): failing-first CRLF regression for record-session insert path cmdStateRecordSession's section-rewrite regexes (src/state.cts:1166, :1195) used literal \\n which cannot match CRLF STATE.md delimiters. The detector regex (CRLF-tolerant via $ under /m) entered the rewrite branch, the writer regex silently no-op'd, but updated.push(...)/ sessionCreated=true ran unconditionally. Result: caller reported recorded:true with 'Resume File' in updated, but the field was never written to disk. With core.autocrlf=input, the CRLF working-tree file produces no git diff, so the bug was invisible. Adds three regression tests covering all three rewrite paths: - CRLF STATE.md with ## Session and Resume file absent - CRLF STATE.md with ## Session and Stopped at absent - CRLF STATE.md with ## Session Continuity (bootstrap shape) Each asserts the field IS on disk (the bug discriminator: the pre-fix command's JSON output looked identical to a successful write). * fix(#2450): CRLF-tolerant session-section rewrite + no-op-detection guard Two regexes in cmdStateRecordSession used literal \\n which cannot match CRLF STATE.md, silently no-op'ing the section rewrite while the CRLF- tolerant detector above entered the branch. The reporter's exact repro: on a CRLF STATE.md with one canonical session field absent, the command returned recorded:true + updated:['Resume File'] but the field was never written to disk. Three changes: 1. src/state.cts:1166 (canonical ## Session rewrite regex): \\n -> \\r?\\n 2. src/state.cts:1195 (## Session Continuity insert regex): \\n -> \\r?\\n 3. Defensive invariant (#2450 class fix per reporter's suggestion): track whether the chosen branch's replace actually matched via callback flag. Only set sessionCreated=true and push to updated when rewriteMatched. Unreachable post-fix, but fail-loud is the right posture for a silent- success gate. If a future drift between the detector and writer regexes reintroduces the asymmetry, the caller will not see false updated entries. Same canonical CRLF-tolerant form already in use at check-command-router.cts :205 (extractPlanDesignatedSections). Same bug class previously fixed in #1658, #1668, #2206, #2449. * fix(#2450): address review followups + add changeset Code-review + security-review both flagged the unreachable else at the Session Continuity branch (defaulted rewriteMatched=true in dead code, re-arming the bug class for future drift). Removed the else; the remaining code path leaves rewriteMatched=false if linesToInsert is empty, preserving the fail-loud posture. Added scope-limitation doc to the rewriteMatched gate: it covers the INSERT path only, not the earlier in-place stateReplaceField successes (which DID land on disk and correctly push to updated unconditionally). Tests: - Normalized STATE_CRLF_SESSION_MISSING_RESUME fixture to match the canonical 6-key frontmatter of STATE_WITH_SESSION (code-review I2). - Added mixed-ending test (LF frontmatter + CRLF body) to close CONTRIBUTING.md:490 'Mixed CRLF/LF newlines' requirement (I1). Added Fixed changeset (code-review H1). * docs(changeset): backfill PR number to 2482
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.
