* test(#1700): add failing-first regression test for spike MANIFEST.md idea scoping Pins the deployed-text contract for spike.md's create_manifest step and spike-wrap-up.md's gather/synthesize/write_skill steps before the fix lands, so the fix commit demonstrates RED to GREEN. * test(#1700): add issue ref to allow-test-rule exemption lint-allow-test-rule-refs.cjs (ADR-456) requires a tracking-issue reference on the same line as any new allow-test-rule: exemption. * fix(#1700): scope spike MANIFEST.md Idea/Requirements per idea key .planning/spikes/MANIFEST.md held one un-keyed ## Idea paragraph and one flat ## Requirements list, while spike.md's own read path (load_prior_context step d, frontier mode) assumed the tree holds several unrelated ideas across campaigns. spike-wrap-up.md then copied that flat Requirements list verbatim into every generated feature-area reference and the generated spike-findings skill, so one idea's requirements leaked into another idea's build as non-negotiable constraints. Scopes both sides by an explicit idea key: - spike.md's create_manifest step now writes MANIFEST.md as ## Ideas > ### {idea-key} subsections (idea paragraph + its own Requirements list), appends a new idea section instead of overwriting an existing one, and migrates a pre-fix flat-shape MANIFEST.md in place instead of discarding it. The ## Spikes table gains an Idea column. Spike README frontmatter carries the idea key. - spike-wrap-up.md's gather/synthesize/write_skill steps resolve each spike's idea key and pull Requirements only from the idea key(s) actually represented among the spikes being wrapped. - sketch.md's MANIFEST.md read (collateral of the same seam) is updated to match the new per-idea section shape. - references/artifact-types.md no longer describes the project-level, durable-index MANIFEST.md as "(per-spike)". Not a docs-vs-workflow conflict: docs/how-to/spike-and-sketch.md already matches this contract ("all spikes are indexed in MANIFEST.md") and needed no change; the defect was internal to spike.md (per-idea read assumption, single-idea write template). * test(#1700): make idea-frontmatter regex CRLF-safe CONTRIBUTING.md's cross-platform portability rules (docs/contributing/ cross-platform-portability-rules.md) ban a bare \n literal matched against fs.readFileSync'd content — Windows checkouts normalize to CRLF and would silently break the assertion. Use \r?\n instead. Found during self-review (code-review skill, Standards axis) before this branch was handed off for verification. * test(#1700): acknowledge emitted-size growth in spike.md, spike-wrap-up.md, sketch.md The differential attribution check (tests/emitted-attribution.test.cjs, ADR-2719) flagged unattributed byte growth in three emitted workflow files. All three grew as a direct, necessary consequence of the #1700 fix (idea-key scoping in spike.md's create_manifest, spike-wrap-up.md's gather/synthesize/ write_skill, and the matching one-line update to sketch.md's MANIFEST.md read) — none of it is incidental prose. Growth stays well under the DEFAULT tier byte cap (40960) for all three files; PRE_PHASE6 does not apply to them (only plan-phase.md/execute-phase.md). * chore(#1700): backfill changeset PR number to 3014 --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.

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
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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.
