* fix(#4250): distinguish a timed-out npm audit from a JSON parse failure npm-audit-baseline.cjs's runPackageLockAudit, and the near-identical auditProductionVulns helper in npm-integrity-gate.test.cjs, both grabbed e.stdout whenever an npm audit child process exited non-zero -- without checking whether the process was actually killed by its 180s timeout. A timeout-killed process's stdout is truncated mid-write, not complete JSON, so JSON.parse threw a misleading "Unexpected end of JSON input" instead of naming npm's registry timeout as the real cause. Root-caused live during a CI investigation: npm's own status page reported degraded service, and the registry's bulk-advisories endpoint was returning 503/hanging, causing npm audit to sit until the timeout fired. Adds a shared isTimeoutKill(error) predicate (checks execFileSync's documented killed/signal fields) and checks it first in both catch blocks, throwing a clear, actionable error before ever reaching JSON.parse. The pre-existing "non-zero exit with complete JSON" recovery path is unchanged and still covered by regression tests.

Extracts buildTimeoutKillError(cwd), used by both callers so the message cannot independently drift. Gives auditProductionVulns the same injectable execFileSyncImpl seam runPackageLockAudit already had, and adds the matching regression tests (timeout-kill throws the clear error; the pre-existing non-zero-exit-with-complete-JSON path still recovers correctly). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#4250): backfill changeset PR number to #4251 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * diag(#4250): surface captured stderr in the timeout-kill error The killed child process's stderr is buffered in-memory by execFileSync and attached to the thrown error, but nothing surfaced it -- the timeout message named the timeout but discarded the one piece of data that could show WHY npm was still running when it fired (DNS stall, TLS handshake stall, a registry-side retry loop, all look identical without it). buildTimeoutKillError now takes the killed error and includes its stderr (or an explicit 'no stderr was captured' note) in the message. This is a diagnostic improvement for the next CI occurrence, not a behavior fix -- local reproduction has directly ruled out npm version (installed the exact CI-bundled 11.17.0 and ran it against this repo: 0.49s, clean), general npm registry reachability (0.4-1.4s locally, repeatedly), and npm ci speed (2m, succeeded) as explanations for the 180s CI hangs. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4260): bounded retry with backoff for npm audit calls, finish the extraction The audit backend has real, independent latency variance from the rest of the npm registry -- measured (see #4260): a bulk-advisories POST took 43.41s vs 0.20s for a plain registry fetch on the same host, and the same endpoint returned no response at all (000) twice in the same window, while status.npmjs.org reported fully operational throughout. Against that, runPackageLockAudit and its near-duplicate auditProductionVulns each made exactly one attempt with no retry -- any single bad moment failed a REQUIRED CI gate on a transport hiccup, not a real advisory. Replaces the single 180s attempt with runNpmAuditWithRetry: up to 3 attempts at 60s each (comfortably above the worst measured working latency) with exponential backoff between them. Only a confirmed timeout-kill is retried; a genuine non-timeout failure still fails immediately, and exhausting all attempts still fails the gate -- per #4260's own caveat, silently disarming a required security check on a transport error is worse than occasionally re-running CI. Also finishes the extraction #4260 flagged as stopped halfway: auditProductionVulns (tests/npm-integrity-gate.test.cjs) duplicated runPackageLockAudit's entire candidate loop, recovery branch, and timeout classification, differing only in npm args and precondition check. It is now a thin wrapper delegating to the newly-exported runInstalledTreeAudit, which shares runNpmAuditWithRetry with runPackageLockAudit -- one implementation instead of two that could independently drift. buildTimeoutKillError now reports attempt count and still surfaces captured stderr from the last kill. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#4260): update changeset for retry/backoff scope Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#4260): budget for two sequential retry-audit calls, close coverage gaps Two review passes on the retry/backoff commit found real gaps: - TEST_TIMEOUT_MS budgeted only one retry-audit call's worst case (210s), but checkTreeAgainstBaseline makes two sequential calls (HEAD tree via auditProductionVulns, baseline tree via runPackageLockAudit) -- combined worst case is ~372s. If both genuinely exhausted retries, node:test's own timeout would fire first and mask buildTimeoutKillError's clear message, undercutting #4250's own fix in that edge case. Recomputed using the same backoff formula the production code uses, so it can't independently drift. - buildTimeoutKillError's default-attempts(1) singular-phrasing branch had zero direct test coverage (nothing calls it with a single attempt anymore) -- a real mutation-testing risk. Added direct tests for both phrasing branches plus the no-error-object case. - runInstalledTreeAudit's null-guard skip paths (missing package.json, missing node_modules) had no tests, unlike runPackageLockAudit's matching paths. Added for parity. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> --------- Co-authored-by: sim <sim@local> Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>
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.
