* fix(#2757): let derived provenance rules attribute a transform change The Phase 2 provenance table (#2722) could only explain a moved emitted path via its `sources`, so a `kind: 'derived'` artifact whose TRANSFORM code changed (not its source) was unattributable by construction: 16 emitted agents/*.toml moved by PR #2566's runtime-artifact-conversion.cts change, with zero agents/*.md in the diff. Adds an optional per-rule `transforms: string[]`. A moved emitted path now attributes via its source OR its transform, reusing sourceSatisfiedBy so exact/prefix matching stays identical for both. Declared narrowly on agents-toml-derived and agents-verbatim (the two families verified to route through the same conversion pipeline) as src/runtime-artifact-conversion.cts, src/install-effort-resolver.cts, and src/model-catalog.cts — never bin/install.js, which would be a blanket escape hatch spanning every installer concern. Also corrects agents-verbatim from kind:'identity' to kind:'derived': measured against origin/next's own fixtures, the same agents/<name>.md hashes differently per runtime (e.g. codex vs claude), which a true verbatim copy cannot do. Verified empirically by installing every runtime and diffing against the raw repo source — none reproduce it byte-for-byte; every one rewrites frontmatter and the hardcoded .claude/ self-reference, and claude additionally gets an effort: line injected. A new assertNoIdentityTransforms invariant rejects an identity rule that declares a non-empty transforms list. Closes #2757 * docs(#2757): flag PR #2566's transform-role files for later verification src/agent-tools-contract.cts (added by #2566, absent on next) and src/agent-install-check.cts (modified +112/-1 by #2566, read-only today) were reviewed for prospective inclusion in AGENT_TRANSFORM_SRCS. Excluded for now: the nonexistent file would fail this fix's own "every declared transform path exists" hygiene test, and the modified file's future role cannot be verified without the unmerged PR's diff. Documents the reasoning, the interim ack-file safety net, and the verification method to apply once these files stabilize, so the next PR touching them has a pre-scoped one-line fix rather than a silent gap.

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.
