* enhancement(#537): migrate code-review-flags to TS source of truth Collapse the hand-written get-shit-done/bin/lib/code-review-flags.cjs to a TypeScript source of truth (src/code-review-flags.cts), compiled by tsc to a gitignored .cjs build artifact at the same path, per ADR-457 (build-at-publish). Second module after the semver-compare pilot (#541). Behaviour is preserved byte-for-behaviour (characterization test added in tests/code-review-flags.test.cjs locks the parser quirks). Adds compile-time type checking: CodeReviewFlags interface + CodeReviewWorkflow literal union. The require() path is unchanged, so code-review.md and the bug-3727 test keep working. The emitted .cjs is gitignored and eslint-ignored, mirroring the pilot. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 9 leaf bin/lib modules to TS source of truth ADR-457 build-at-publish, batch 1 (pure leaf modules, 0 sibling-deps): 001-legacy-orphan-files, context-utilization, redaction, artifacts, command-arg-projection, clock, ui-safety-gate, review-reviewer-selection, clusters. Each moves to src/*.cts (strict TS, typed), compiled by tsc to a gitignored .cjs at the same require() path; behaviour preserved byte-for- behaviour. Adds src/node-globals.d.ts (minimal ambient shim; "types":[]). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#537): add @types/node, drop hand-rolled node-globals shim ADR-457 migration infra: replace the temporary src/node-globals.d.ts ambient shim with @types/node@22 + "types":["node"] in tsconfig.build.json. Unblocks migrating the ~49 remaining bin/lib modules that use node:fs/path/os/ child_process. Build + full suite (3030 pass) + lint all green; no .cts type changes were needed (real Node types matched the shim). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 9 more bin/lib modules to TS (batch 2) ADR-457 build-at-publish. Clean leaves: installer-migration-report, prompt-budget. Type-error-prone leaves (were tsconfig.lint-excluded; now strict-typed and removed from that exclude list): secrets, phase-lifecycle, workstream-name-policy, decisions, validate, schema-detect. Plus runtime-name-policy. Strict type fixes narrow unknown->concrete domain types (no any/ts-ignore); behaviour preserved. Full suite green, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate runtime-slash to TS (cross-import proof) ADR-457. First cross-module TS->TS import: src/runtime-slash.cts imports ./runtime-name-policy.cjs and tsc resolves the sibling .cts types under strict (no declaration files; NodeNext .cjs->.cts mapping), emitting a correct require("./runtime-name-policy.cjs"). Confirms the recipe for coupled modules, which must be migrated in dependency order (leaves-up). Suite green, lint clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 10 more bin/lib modules to TS (batch 3) ADR-457 build-at-publish, Wave-1 leaves: event, workstream-inventory-builder, plan-scan, fallow-runner, project-root, installer-migration-authoring, update-context, 000-first-time-baseline, runtime-homes, model-catalog. Strict typing fixed real issues (narrowing unknown, qualified fs/path calls, removed unnecessary casts); plan-scan/project-root/workstream-inventory-builder dropped from tsconfig.lint exclude. Behaviour preserved; suite green, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 5 large Wave-1 leaves to TS (batch 4) ADR-457 build-at-publish: configuration, state-document, shell-command- projection (42 dependents), security, command-aliases. shell-command- projection keeps a namespace child_process import for mock-intercept testability. loadConfig/migrateOnDisk emit synchronously (every caller uses them sync; the one awaited migrateOnDisk caller tolerates a non-Promise) — full suite (3030 pass) confirms behaviour preserved. configuration/ state-document/command-aliases dropped from tsconfig.lint exclude. Also fixes the malformed batch-3 changeset frontmatter (type/pr) that failed lint:docs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 6 Wave-2 modules to TS (batch 5) ADR-457 build-at-publish: config-schema, model-profiles, 002-codex-legacy-hooks-json, logger, active-workstream-store, adr-parser. First batch importing already-migrated siblings (configuration, model-catalog, shell-command-projection, redaction, security) via ./sibling.cjs specifiers. Strict type narrowing (typeof guards over String(unknown)); behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 5 large Wave-2 modules to TS (batch 6) ADR-457 build-at-publish: graphify, install-profiles, intel, installer-migrations, worktree-safety. installer-migrations preserves its dynamic require() loader for numbered migration modules (scoped lint suppressions). Strict typing (typeof guards over String(unknown)); behaviour preserved; suite 3030 pass, lint 0 errors. Wave 2 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate Wave-3 modules to TS (batch 7) ADR-457 build-at-publish: planning-workspace, runtime-artifact-layout, command-routing-hub, drift. Uses `import x = require()` for export= siblings; drift's lazy require of runtime-slash hoisted to a top-level import (verified non-circular). Behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate small Wave-4 modules to TS (batch 8) ADR-457 build-at-publish: cjs-command-router-adapter, phase-command-router, surface, roadmap-upgrade. Typed the hub router handler results as the HubResult discriminated union; surface drops 4 genuinely-unused imports. Behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate core hub (2.5k LOC, 68 dependents) to TS (batch 9) ADR-457 build-at-publish: get-shit-done/bin/lib/core.cjs -> src/core.cts, preserving all 63 exports via export=. All sibling deps already migrated (shell-command-projection, model-profiles, model-catalog, worktree-safety, planning-workspace, project-root, configuration, config-schema). Strict types, no any/ts-ignore; config-schema lazy require hoisted (non-circular). Behaviour preserved (independently verified: core's shard 3030 pass / 0 fail). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537): make ESLint-coverage + test-sprawl checks migration-aware #551 test hardcoded 12 now-migrated modules as "hand-written, must be linted"; that invariant is obsoleted by the ADR-457 migration. Rewrite it to a filesystem-driven invariant that holds at every stage: a bin/lib/*.cjs must be eslint-ignored IFF it has a src/*.cts source (tsc-generated), else linted (covers package-identity, which has no TS source). Also eslint-ignore config-types.cjs (has a src counterpart) and drop the redundant tests/clock.test.cjs (clock already covered by clock-seam + bug-474 tests), which tripped the lint-test-file-count ratchet. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 9 Wave-5 router/inventory modules to TS (batch 10) ADR-457 build-at-publish: phases/verify/init/agent/task/validate/roadmap/state command routers + workstream-inventory. Router handler results typed against core's exported shapes; behaviour preserved (caught+fixed a --verify boolean flag regression mid-migration). Full suite green across all shards (only the 4 local gpg-env changeset-notes failures remain; CI passes them). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 7 Wave-5 modules to TS (batch 11) ADR-457 build-at-publish: gap-checker, docs, check-command-router, frontmatter, learnings, gsd2-import, profile-pipeline. Behaviour preserved; full suite green across all shards (only the 4 local gpg-env failures remain). Also broadens atomic-write-coverage.test.cjs to accept the tsc-compiled namespace-import form while still asserting platformWriteSync is called (safety guard intact). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate config + profile-output to TS (batch 12) ADR-457 build-at-publish: config (729 LOC), profile-output (1142 LOC). All exports preserved; cmdMigrateConfig de-asynced (migrateOnDisk is sync, awaited caller tolerates it). Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Wave 5 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 5 Wave-6 modules to TS (batch 13) ADR-457 build-at-publish: template, uat, workstream, roadmap, audit. Behaviour preserved (dead toPosixPath import dropped from audit; inline requires hoisted). Suite green across all shards (only the 4 local gpg-env failures). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate commands + state hubs to TS (batch 14) ADR-457 build-at-publish: commands (1305 LOC), state (2074 LOC, 17 dependents). All exports preserved; inner requires kept non-hoisted where load-order matters (install.js, per-call security); acquireStateLock cast inlined to preserve the err.code source token a structural test inspects. Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Wave 6 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate milestone to TS (batch 15a, hand-authored) ADR-457 build-at-publish: milestone -> src/milestone.cts. Authored directly (subagent capacity was unavailable). Also relaxes core.output()'s 3rd param to optional, matching its real always-optional call contract (unblocks remaining 2-arg output callers). Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate phase, verify, init to TS (batch 15, final modules) ADR-457 build-at-publish, Wave 7 (the last hubs): phase (1608 LOC), verify (1615), init (2113). Adds src/package-identity.d.cts so verify can import the permanently value-baked package-identity.cjs under strict TS. Fixes two regressions the migration introduced in verify: restore cmdValidateHealth's `return result` (callers/tests read result.warnings — it is NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour intact). Full suite green across all shards (only the 4 local gpg-env failures); lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is deleted per ADR-457's final step. Also gitignore the tsc-generated config-types.cjs (was still committed) for consistency with every other emitted artifact. package-identity.cjs stays value-baked (declared via src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g <dir>` and git installs run the `prepare` lifecycle — which was missing — so the unpacked install shipped without the compiled .cjs and failed at startup with "Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job). Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does NOT run for registry consumers (they get the pre-built tarball), only for source/local/pack installs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are always present on disk: - check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the `prepare` build (tsc) — but it runs before deps are installed, so tsc is absent and it misreported the lockfile as out of sync. Add --ignore-scripts (a lockfile check must not build). - the lint-tests job installs with --ignore-scripts (no prepare build), but lint:skill-deps require()s the built install-profiles.cjs. Add an explicit `npm run build:lib` step after install. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step) prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`, which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT — breaking it with "Invalid format". build:lib (tsc) is silent on success and is all the unpacked/source install needs (the smoke-unpacked assertions exercise gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches prepack. build:hooks still runs on prepublishOnly for real publishes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): wire Stryker mutation gate to build-at-publish layout The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were generated artifacts and (b) included modules with no coverage in the command's test set. Rework: mutation.yml now derives changed COVERED modules from src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc was ~3x over the 30-min CI budget). NOTE: with the gate now correctly measuring the covered modules, their actual mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap (adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver — a maintainer decision. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537): raise mutation coverage of covered modules above the 50 gate Adds focused example-based unit tests that kill surviving mutants in the two lowest-scoring covered modules: - tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9% - tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4% Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered modules now scores 82.25% (>= break 50); every covered module is >= 68%. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix The serial Stryker run timed out at 30 min once the migration's added tests made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the gate completes well under budget — folded into this PR (was tracked as #609) because it's a prerequisite for this PR's mutation gate to pass. - scripts/mutation-matrix.cjs: single source of truth (covered-module -> test files) computing changed covered modules from git diff -> {has_work, matrix}. - mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name "Stryker mutation score (changed files only)" so branch protection is unchanged. Per-shard jobs report as "Stryker (<module>)". - stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back to the full command locally). Closes #609. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note Per-module sharding revealed that active-workstream-store (46.5%) and frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from the bloated 300-test command; on their own tests they were below the gate. Add focused unit tests: - tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9% - tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4% Both wired into scripts/mutation-matrix.cjs (per-module test map) and stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50 with only their own tests (config-schema/context-utilization/prompt-budget/ adr-parser already did). Also removes the leftover blacksmith TODO comment — GitHub-hosted runners only; speed comes from parallel per-module shards. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the way the per-module CI shard runs it) — an earlier ~98% reading was inflated by accidentally running the full multi-module command. Add 96 targeted tests to tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans): scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear the gate on their own tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 <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, Gemini 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, 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, 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:

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.
