* fix(#2590): emit Workflow scripts the Workflow tool accepts; make the backend reachable Every emitted script was rejected. Four invalid constructs, the first fatal on its own, so the Workflow backend could never dispatch a wave: 1. no `export const meta = {…}` first statement -> whole script rejected 2. resumeFromRunId("<id>") -> "resumeFromRunId is not defined". It is a Workflow TOOL INPUT parameter, not a script function. The run id still reaches the caller via summary.resumeRunId, to pass as that input. 3. budget(<n>) -> "budget is not a function". `budget` is a read-only object { total, spent(), remaining() } fed by the caller's token directive; a script cannot set it. Recorded as intent in a comment. 4. parallel(agent(…), agent(…)) -> "parallel() expects an array of functions". Now parallel([() => agent(…), …]) — passing agent() results directly also started every agent eagerly, before parallel() could bound concurrency. The single-plan stage had its own branch with the same parallel() defect; both branches are now one array-emitting path. Waves also emit phase() calls whose titles match meta.phases exactly, so progress groups correctly. Two secondary defects kept the script from ever being REACHED — which is why this shipped undetected: 5. NOTHING resolved the Agent SDK version. The fragment claimed there was "no scriptable way" to introspect it and told callers to omit the flag, so gate 5 returned agent_sdk_version_unknown on every automated run while `capability state` still reported active:true. True for bash, false for Node: the router now reads the installed @anthropic-ai/claude-agent-sdk version, walking node_modules up the tree and reading package.json directly — require.resolve throws ERR_PACKAGE_PATH_NOT_EXPORTED because the SDK's exports map does not expose ./package.json. Precedence: explicit flag > GSD_AGENT_SDK_VERSION > installed. Fail-closed is preserved; an unresolvable version still declines to inline. A too-old SDK now reports the truthful agent_sdk_version_below_floor instead of unknown. 6. The runtime fallback was `--runtime > GSD_RUNTIME > 'unknown'`, diverging from the canonical `GSD_RUNTIME > config.runtime > 'claude'`, so any invocation without --runtime reported runtime_not_claude on an ordinary Claude project. Now delegates to runtime-slash.resolveRuntime. The fragment's `${AGENT_SDK_VERSION:+--agent-sdk-version "$AGENT_SDK_VERSION"}` snippet is removed rather than repaired: it was also shell-dependent — zsh does not word-split unquoted parameter expansions, so it collapsed to a single argv element, argValue() never matched, and the run failed into the same agent_sdk_version_unknown, indistinguishable from genuinely unknown. Auto- resolution removes the need for the construct entirely. Verified with the issue's own repro: no flags now reaches the version gate; an SDK above the floor yields backend:"workflow" with a script that parses as a real ES module.

HIGH — gsd-core/bin/lib/capability-registry.cjs was stale, and `lint:ci` was already RED because of it. The registry embeds the fragment text INLINE, so the shipped/installed copy still taught the exact broken contract this PR fixes: the old `${AGENT_SDK_VERSION:+…}` bash line and the "OMIT the flag when unknown" guidance. Regenerated. (I had read `lint:ci` by grepping its output instead of checking its exit code, so I recorded a red chain as green — checking $? now.) HIGH — three existing tests asserted the OLD broken shape and would have failed CI; none was touched by the first commit: tests/fix-2285-claude-orchestration-wiring.test.cjs — matched resumeFromRunId("…") tests/claude-orchestration.test.cjs — .includes('budget(') tests/claude-orchestration-command-router.test.cjs — .includes('budget(') Each now asserts the corrected contract: the id/pool reaches the caller via summary, and neither construct is ever CALLED. Two sibling assertions had also gone vacuous — `.includes('resumeFromRunId')` still passed, but only because the new explanatory COMMENT contains that substring, not because anything is wired. Rewritten to assert the real property. MEDIUM — duplicate wave ids were never rejected. Plan-id uniqueness was checked within a wave, but nothing checked wave ids across waves. That was harmless before; it is not now, because each wave emits a `phase("Wave <id>")` call plus a matching meta.phases entry and the tool matches titles by exact string — two waves sharing an id would collapse into one progress group and misattribute the second wave's agents to the first. Rejected at validation, with tests either side of the boundary. MEDIUM — the fragment contradicted itself (its "Manifest construction" header still listed $AGENT_SDK_VERSION as orchestrator-built) and, more seriously, never told the orchestrator to pass summary.resumeRunId as the Workflow tool's resumeFromRunId INPUT. Since this PR moves resume from a broken in-script call to a tool-invocation input, an implementer following only the fragment would have silently regressed phase-resume to a no-op. Both fixed. MEDIUM — docs/how-to/enable-claude-orchestration-workflow-backend.md and docs/explanation/claude-orchestration-capability.md documented `resumeFromRunId("<id>")` and `budget(<tokens>)` as current correct output — teaching the bug as the feature. Updated to the real contract, including the required meta block and the thunk-array parallel() form. (The changeset is `Fixed`, so the docs gate exempts this; it is corrected because it is wrong, not because a gate demanded it.) LOW — the router's top-of-file comment still described the divergent `--runtime > GSD_RUNTIME > 'unknown'` chain as current, ninety lines above the fix; and inserting resolveInstalledAgentSdkVersion had orphaned resolveDetectionArgs' JSDoc above the wrong function. Both repaired. lint:ci now exits 0 (verified by exit code, not by reading output).

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
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.
