* feat(#1733): normalize-path-in-content production AST rule (Phase 5) ADR-1703 Phase 5 — the first production-code rule. local/normalize-path-in-content (src/**/*.cts, @typescript-eslint/parser): flags a path-returning fn result (path.basename excluded — returns a separator-less filename) interpolated into an @-reference / config-dir markdown body without .replace(/\\/g,'/') normalization, per RULESET.CONTENT-PATH-NORMALIZATION / DEFECT.WINDOWS-PATH-LEAK-IN-MARKDOWN-CONTENT. Build-and-assess found the canonical defect site (computePathPrefix) already compliant and only 1 src/ hit — a false positive (path.basename in a status message) — eliminated by narrowing (exclude basename; require a real @-ref/ config-dir marker, not bare .md). 0 src/ violations: clean forward-prevention. The out-of-band disable-ban now scans src/**/*.cts too (typescript-estree) so the production rule also cannot be eslint-disabled. Registered (error) + PROTECTED_RULES; CONTEXT.md predicates + how-to doc updated. - RuleTester suite (26 cases) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(#1733): add changeset for Windows agent-skills path-leak fix Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix: harden mutation-matrix.cjs stdin read against EAGAIN on non-blocking pipe scripts/mutation-matrix.cjs read piped stdin via readFileSync(process.stdin.fd). On macOS libuv marks the stdin pipe fd non-blocking, so a synchronous read can throw EAGAIN before the writer fills the pipe — intermittently, under heavy CI shard load — aborting the script (status 2) and flaking mutation-matrix-ratchet. Replace with readStdinSync(): an fs.readSync loop that retries on EAGAIN (1ms synchronous Atomics.wait yield), stops on 0-byte/EOF, and rethrows other errors. Deterministic regression test injects EAGAIN via an fs.readSync monkeypatch. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ci: re-run golden-install-parity on src/lib + installer changes (close drift guard) golden-install-parity hashes every installed bin/lib/*.cjs per runtime, so it must re-run whenever the built lib could change. ci-test-scope selected it for neither src/** nor installer changes, so a source-only edit (e.g. #1691's milestone.cts/roadmap.cts) recompiled bin/lib and silently drifted the golden fixtures past the scoped lane. Add golden-install-parity.test.cjs to both the 'TS runtime sources' and 'installer and package layout' selection rules, with behavioral regression tests for each.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
