* feat(#896): Capability Registry generator + UI pilot (ADR-857 phase 3a-impl) First phase-3 code: the Capability Registry generation pipeline, built against the ADR-894 contract and NOT wired into the live loop (registry-only, per the staged-cutover design). - capabilities/ui/capability.json — the UI pilot (ADR-894 worked example): 2 skills, 2 agents, 3 config keys, 2 steps + 1 gate, with `when` activation. - scripts/gen-capability-registry.cjs — --write/--check generator. Hand-rolled schema validation (envelope + role-typed feature/runtime bodies + typed steps/contributions/gates + when + gate-check variants); cross-capability invariants (single ownership; requires exist+acyclic+tier-monotone; config-key ownership exclusive, collision-vs-central as a pending-migration warning); hooks validated against an inline LOOP_HOST_CONTRACT (3a-impl-2 swaps its source to the generated-from-workflows contract); GLOBAL point-ordered consumes-satisfiability; materialized byLoopPoint ordering (produces/consumes topo-sort); emits gsd-core/bin/lib/capability-registry.cjs (role-partitioned indexes + requiresClosure). Prototype-pollution guards (Object.create(null) + inline literal key checks) + fragment.path traversal guard. - gsd-core/bin/lib/capability-registry.cjs — committed generated artifact (mirrors package-identity.cjs: script-generated, tracked, linted, regenerated on build, drift-tested), wired via the new `gen:capability-registry` build step. - tests/capability-registry.test.cjs — 72 tests: schema + invariant + hook + ordering + adversarial (path-traversal, proto-pollution, runtime body, self-consume, cycles, collisions) + committed-file staleness guard. New-CLI-module checklist (INVENTORY 97->98, MANIFEST, ARCHITECTURE), CONTEXT.md "Capability Registry" un-[Planned]'d. Nothing wired into install/surface/loop. Gates: lint, code-review (4 bugs fixed), security-review (path-traversal + prototype-pollution fixed), codex adversarial-review ×3 (8+ findings fixed, confirmed sound), clean-build docker 13190 pass / 0 fail. Closes #896 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#896): CRLF-agnostic --check for capability-registry staleness (Windows) The committed capability-registry.cjs staleness guard failed on Windows CI only: git checks out the committed .cjs as CRLF (autocrlf, no .gitattributes) while the generator emits LF, so the byte-for-byte --check comparison mismatched. Normalize line endings on both sides of the --check comparison (no .gitattributes change, no change to the LF the generator writes). Adds a regression test simulating the Windows CRLF checkout. --------- 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:
/gsd-new-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.
