* chore(#2992): widen the when= grammar and key the section manifest per workflow Epic #1671 Phase 6.1. Two blockers stopped the fragment model reaching any file beyond execute-phase.md: the when= vocabulary was frozen at 4 atoms (3 execute-phase-specific), and the section manifest was single-workflow by construction with 'execute-phase' hardcoded into buildSectionManifestField. - widen WHEN_VOCABULARY 4 -> 14 via a coordinated ADR-1671 amendment; the grammar stays CLOSED (one atom, no operators, negation or nesting) and WHEN_PREDICATES stays a hand-written literal map, never deriving a predicate from its atom string - InvocationFacts gains flags: ReadonlySet<string> plus three computed state booleans; add the missing reverse vocabulary/predicate parity guard - key the manifest artifact per workflow; a stale flat {sections:[...]} artifact now fails shape validation instead of being misattributed - wire the field into six init entry points and parse the flags each needs An atom ships only with both a real consuming section and a fact the init seam actually computes. Six surveyed atoms are withheld because their workflows have no dedicated init entry point; an atom without a computed fact evaluates false forever and silently disables its own section. Fixes a defect found while wiring: parseNamedArgs always materializes a boolean flag key, so folding its false into the absent sentinel is required or every flag reads as present and gating is silently always-on. Also resolves ADR-1671:194 by measurement: --mvp stays unmarkable, because its interleaved sites are always-run flag resolution and a ~340 byte block that already delegates lazily. Refs #2992 * fix(#2992): treat any falsy option value as an absent flag and reject unsafe manifest read paths Findings from two orthogonal reviews (Claude /code-review + an isolated adversarial pass); both independently reproduced the first one. - MAJOR: the flags-builder treated only `undefined` as absent, but parseNamedArgs yields `null` for an absent value-flag and `false` for an absent boolean-flag, so `--granularity` read as present on every plan-phase invocation. Fixed at the root: a flag is present iff its option value is truthy. The six per-handler `|| undefined` folds are now redundant and removed, which also closes the duplicate-translation and missed-onboard-handler findings. - MAJOR: state:needs-codebase-map had zero coverage. Added unit, property and real-CLI integration tests. - MINOR: reject absolute, UNC/drive and `..`-traversing `read` paths in the manifest, degrading the whole load to null like every other shape violation. Verified: `/etc/passwd` previously reached section_manifest.read. - MINOR: corrected a stale "4 to 20" doc comment; the vocabulary is 14. Refs #2992 * test(#2992): update the generator suite for the per-workflow manifest shape The remote matrix went red with 5 unique failures, identical on linux-node22 and linux-node24, all in tests/gen-section-manifest.test.cjs. Re-keying the artifact to {workflows:{...}} left this suite asserting the old flat {sections:[...]} shape; nothing else in the tree still does. - three tests read manifest.sections.length, now undefined; retargeted at workflows.<name> with their original intent preserved (a fenced or loop-host marker still asserts NO section is produced, not merely a changed count) - the stale-manifest test wrote its fixture in the OLD shape, so it tripped shape validation and stopped exercising staleness at all. Its fixture is now valid-but-mismatched so FAIL_STALE is genuinely reached again. - added the coverage that exposed: a pre-6.1 flat artifact must report FAIL_MANIFEST_MALFORMED_SHAPE. That is the real upgrade path for an installed tree and nothing covered it. Refs #2992 * chore(#2992): backfill changeset pr number to 3013 --------- Co-authored-by: sim <sim@local>
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.
