* test(#4740): pin the per-step role-family partition Failing-first coverage for the Loop Host Contract role partition. At this commit crossCheckRoleFamilies does not exist, so the rows throw "crossCheckRoleFamilies is not a function" -- the RED proof they bind to behavior rather than restating it. ADR-894 section 3 assigns roles per step but parenthesises the assignment as "(illustrative roles)", and nothing enforced it. The only thing standing in the way was a single deepEqual in this same file, which is editable prose. Rows cover: each step's own family accepted; a strict subset accepted; a foreign role rejected at every step; an unknown role rejected; an unknown step failing CLOSED; capitalization not silently matched; every offending role reported rather than only the first; and purity, because buildContract puts the same array into the generated contract. Two rows exist because an earlier cut of this suite was vacuous. The purity fixture is deliberately UNSORTED -- an alphabetically-sorted fixture cannot fail an in-place sort(), and the mutant was being killed by three unrelated rows instead. A parity row asserts ROLE_FAMILY and ROLE_TO_AGENT cover the exact same role-name domain, both directions: they are parallel constants over one domain, so divergence is the generative-fix class CLAUDE.md names. Every negative row asserts the offending ROLE NAME and the STEP NAME appear in the message. A count-only assertion survives a mutant that reports the wrong role, which the 80% Stryker gate would surface only after a full CI round-trip. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#4740): reject a cross-family agent-role declaration Orchestration and execution are distinct functions of the loop and must not drift into one another. That partition was real but unenforced: ADR-894 section 3 calls its own role assignment "illustrative", and the generator accepted anything. Adding orchestrator to execute-phase.md's agent-roles line compiled, --check passed once regenerated, and capability-validator.cjs then began accepting into:"orchestrator" at every execute point. ROLE_FAMILY maps every role to one of orchestration, planning or execution. EXPECTED_FAMILY_BY_STEP gives each of the five steps exactly one family. crossCheckRoleFamilies rejects a cross-family role, a role outside the vocabulary, and an unknown step. It reports every offender, not the first. It fails CLOSED on an unknown step, deliberately diverging from assertPointsCoverage's "unknown step -- caught elsewhere". For points that is true: the canonical-set and duplicate checks catch it. For roles there is no second net, so failing open would leave an unknown step as the one input that bypasses the gate. crossCheckRoles' orchestrator exemption is untouched. ROLE_TO_AGENT maps roles to agent FILES and the orchestrator is the host, owning none -- admissibility and agent-file presence are separate concerns with separate checks. Additive to section 3's existing rule that contribution.into must be a member of the step's agentRoles, which is unchanged. That governs what a CAPABILITY may target; this governs what a WORKFLOW may declare. No capability is affected, and all five workflows already declare single-family sets, so the gate is green on the commit that introduces it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#4740): make the ADR-894 role assignment normative Section 3 parenthesises its per-step role assignment as "(illustrative roles)". That word was accurate about the list's PURPOSE -- it illustrated the shape of a generated contract entry -- and wrong about its STATUS, because the assignment was load-bearing from the moment the generator consumed it. Read literally it makes the partition an example rather than a rule. Appended as a dated in-place section per docs/contributor-standards.md, which records that an accepted ADR is never rewritten and names this the default pattern. Section 3's original body is untouched. The amendment states the three disjoint families, the one family each step admits, that a step may declare a strict subset but never outside it, and why this is a clarification rather than a new decision: the contract is generated from the workflow markers "so it cannot drift into a lie", and all five workflows have always declared single-family sets. What was absent was any statement that it is required, and any check that it holds. It also pins the distinction that is easy to re-merge: contribution.into being a member of agentRoles governs what a CAPABILITY may target and is unchanged; the family rule governs what a WORKFLOW may declare. The CONTEXT.md glossary entry for the Loop Host Contract records the same, beside the agent-reference drift guard it already documented.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#4740): backfill changeset pr number Replaces the pr:0 placeholder with 4742 now that the PR exists. Verified with GITHUB_BASE_REF=next, the way CI runs them: changeset lint and lint:docs both go from invalid_pr(0) to ok. Without that env both report success without evaluating the branch at all. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4740): stop injecting the orchestrator procedure into executors claude-orchestration declared a contribution at execute:wave:pre with into:"executor". loop-hook-dispatch.md defines a contribution as "inject fragment.inline verbatim into the context for the role named in into", so its 267 lines were injected into EXECUTOR prompts whenever the capability was enabled. Those lines are orchestration end to end -- construct a wave manifest, resolve the dispatch backend, invoke the Workflow tool to spawn executors, bridge per-agent results into the merge chain. An executor can act on none of it. Retargeting to into:"orchestrator" would not have been a fix. ROLE_TO_AGENT carries no orchestrator entry by design: the orchestrator IS the host, and the host's procedure lives in execute-phase.md. A step's agentRoles enumerates agents a capability may inject context INTO, so adding orchestrator there would model the host as an injectable agent -- the same category error pointed the other way, and it would need an exception carved into the partition the same issue just made normative. So the defect is the mechanism, not the label. A contribution injects into an agent's context; "replace step 3's inline dispatch loop" is a change to what the HOST does. The contribution channel was serving as a host-behaviour directive because it was the only channel available at an execute point. The entry is removed. plan:post into:"planner" is correct and untouched. The procedure is preserved verbatim at docs/workflow-backend-dispatch.md inside the capability -- it is the only copy in the repo -- and is no longer injected anywhere. Consequence, not softened: the Workflow backend now has no loop wiring. Detection, emission and config remain and the design is intact, but nothing dispatches it. Under the separation ADR-1143 itself asserts it never had a legitimate channel; ADR-1143's own audit already records the end-to-end path has never been exercised. Wiring it properly needs a host-level mechanism that does not exist today. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4740): invert the stale execute:wave:pre registry assertions Removing the contribution left four surfaces asserting or describing the old state. Caught by an isolated review before a verification run was spent, which is the point of reviewing first: the first of these was a guaranteed CI red. execute-wave-post-gate-pipeline-e2e asserted against the REAL generated registry that byLoopPoint['execute:wave:pre'] held exactly one contribution with capId claude-orchestration. It now holds zero. Inverted to assert exactly 0 -- not a vague >= 0 -- and the #2285 comment above it now explains the current state rather than the one it was written for. CONTEXT.md's Claude Orchestration entry claimed two contributions at wired points. It is now one, and the entry's execute:wave:post label was already wrong before this change: the manifest said execute:wave:pre. Rewritten to one plan:post contribution, why the execute-point one was removed, and where the procedure now lives. One assertion in claude-orchestration.test.cjs could not fail. It tested for the prose "(into the executor)" while the doc says "(`into: executor`)", so no plausible wording matched it and the paired plan:post assertion was carrying the row. Replaced with a check on the structural claim, and proved RED by restoring the two-contribution wording before reverting. The moved procedure keeps section headings that speak as a live contribution -- "When this contribution is active", "Why execute:wave:pre". Preserving the body verbatim was deliberate, so the headings stay and an editor's note under the header explains why they read that way. A sweep of all 17 files referencing byLoopPoint found no further siblings: the remaining hits are a synthetic capability fixture and an empty-points test that already expected no active hooks, both correct before and after.

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.
