* feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6) ADR-1703 Phase 6 of the cross-platform portability epic (#1702). Adds the second production-code portability AST rule + the ADR-mandated glob expansion to bin/install.js and scripts/build-hooks.js. - eslint-rules/require-fs-op-fallback.cjs: flags an unguarded fs.rename / fs.renameSync (the atomic-publish primitive named first in DEFECT.WINDOWS-FS-OPS.symptom) that is NOT inside a try/catch whose handler references a transient errno ('EPERM'/'EBUSY'/'EACCES' or a *RETRY_ERRNOS set) AND NOT behind a Windows platform guard. A catch that silently swallows or cleans-up-and-rethrows without an errno check does NOT satisfy the defect's 'never silently swallow' clause. copyFile/unlink are deliberately not flagged (they are the fallback primitives per the defect's own fix-forward). Scope narrowed to rename per Phase 5's precision discipline; documented on #1740. - src/shell-command-projection.cts: export retryRenameSync(from, to) — the drop-in bounded-retry helper over the existing atomicRenameWithRetry. - 27 bare fs.renameSync sites across 11 modules routed through retryRenameSync (capability-lifecycle/lock/source, installer-migrations, milestone, phase, planning-workspace, roadmap-upgrade, runtime-hooks-surface, state, workstream). Idempotent on POSIX; resilient to AV/indexer transient locks on Windows. - eslint.config.mjs: register rule at error on src/**/*.cts; new focused portability-rules block covering bin/install.js + scripts/build-hooks.js (ADR-1703 L124-126 glob expansion — both files are compliant: zero rename violations). - tests: 15-case RuleTester suite; portability-rule-disable-ban extended (PROTECTED_RULES + scans bin/install.js/build-hooks.js with shebang handling); ci-test-scope portability-lint selection rule. - CONTEXT.md DEFECT.WINDOWS-FS-OPS predicate rewritten to point at the rule; docs/contributing/cross-platform-portability-rules.md reference + how-to. Closes #1740 * chore(#1740): backfill changeset pr:1742 * fix(#1740): tighten require-fs-op-fallback precision (codex review HIGH-1/HIGH-2) Addresses two false-negative findings from the codex (gpt-5.5/high) adversarial review of PR #1742: HIGH-1 — a catch that REFERENCES a transient errno but only rethrows (no retry/fallback) was marked compliant. The DEFECT.WINDOWS-FS-OPS fix-forward requires retry, not just recognition. Fix: catchHandlerHasRetrySignal now requires a loop `continue` backedge OR a `return <call>` delegation; a bare rethrow is flagged. The misleading `/* retry logic */` valid test is replaced with a real retry loop, and the rethrow-only shape is added as invalid. HIGH-2 — the nested-try ancestor walk treated an OUTER errno-catch as protecting the rename even when an INNER catch intercepted/swallowed the error (the outer catch is unreachable). Fix: isInsideTransientErrnoTryCatch now stops at the NEAREST enclosing TryStatement WITH A CATCH HANDLER whose block contains the rename (try-finally is skipped — it doesn't catch); outer catches are no longer consulted. The unsound nested-try valid test is converted to invalid, and a try-finally-skipped valid case is added. Verified: 17 RuleTester cases pass; zero new production violations (the 27 fixed sites use retryRenameSync; the real retry loops — atomicRenameWithRetry, capability-ledger/consent, build-hooks — remain compliant via continue/errno); lint:ci green; disable-ban + vocab-drift green. --------- Co-authored-by: review-bot <review-bot@gsd>
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.

Once installed, start your first 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.
