* fix(#2617): project verification next_command onto the runtime's command surface `src/verification.cts` stored and synthesized hard-coded `/gsd:…` command strings with no runtime context, and `phase complete` relayed that raw field straight into its verification-blocked error. On a Codex project the suggested next step was `/gsd:execute-phase`, a surface Codex does not install — it installs `$gsd-execute-phase`. The colon form is wrong twice over: `runtime-slash.cts` documents that "the colon form is never emitted", so EVERY runtime — not just Codex — was being handed a deprecated shape. Fixed at the one routing seam rather than per caller: - The routing table now stores BARE command names (`execute-phase`), never a prefixed literal. A prefixed literal in the table is what leaked. - A single `projectNextCommand(bare, runtime, tail)` helper runs every return path through `formatGsdSlash`, preserving the argument tail (`01 --gaps`) untouched. An empty command stays empty, so "no next step" never becomes a bare prefix. - `readVerificationStatus` accepts `opts.runtime`; `cmdVerificationStatus` and `phase complete` pass `resolveRuntime(cwd)`. The default is `claude`, which yields the canonical `/gsd-` hyphen form. All four routed states are covered: missing, unknown, gaps_found, stale. `init.cts` keeps its own projector deliberately. It already formats correctly, and its command CONTENT differs from the router's on purpose (it appends the phase number to `execute-phase`, and routes `human_needed` to `verify-work`). Consolidating them would silently change `init`'s user-visible output, which this issue did not ask for — so the divergence is left intact and the new tests instead pin the property that matters on both surfaces: no raw colon form escapes. Failing-first record: `origin/next:src/verification.cts` carried the four `/gsd:` literals (lines 101, 108, 382, 392), and 11 existing assertions in tests/verification-status.test.cjs asserted the colon form. Those 11 are corrected in this commit — they passed before the fix and fail after it, which is precisely the regression this closes. Tests are folded into the module's primary suite rather than added as a third file (`lint-test-file-count` caps the `verification` module at two, and consolidating is its documented remedy — growing the allowlist is not). The `phase complete` assertion reads `res.error`, not `res.stderr`: `runGsdTools` exposes a clean non-zero exit's stderr as `error`, and reading the wrong field yields '' and makes the whole check vacuous — which is how this user-visible path stayed untested. Closes #2617 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QT3ibz5qJuDuGqpTGRYVGf * test(#2617): scope the new hooks to their describes; cover gaps_found through the CLI Two findings from the orthogonal review of the first commit, both in the tests this change added. 1. The folded block's `beforeEach`/`afterEach` were declared at MODULE scope. node:test applies module-scope hooks to every test in the file, so hooks added for the #2617 suites also wrapped the ~40 pre-existing tests in verification-status.test.cjs — making an unrelated block a single point of failure for them (currently benign, but a throwing hook would have failed suites it has nothing to do with). They now install inside their own describes via a small `useProjectionPhaseDir()` helper, with a comment recording why. 2. The live-CLI `phase complete` test exercised only the `missing` state, so a regression in any other routed branch would have shown up in the router's return object but not in the text a user actually reads. Added a `gaps_found` case per runtime, asserting the projected `plan-phase <N> --gaps` reaches the blocked-completion error. Whole file verified green: 48 tests, 48 pass — the ~40 pre-existing ones included.

That project fixture configures no runtime, so it takes the `claude` default, which now yields the canonical `/gsd-verify-work 01` hyphen form. The colon form this asserted is exactly the deprecated shape #2617 removes — `runtime-slash.cts` documents that "the colon form is never emitted". Like the eleven corrected in the first commit, this assertion passed before the fix and fails after it, which is the regression record rather than a test being loosened: the surrounding assertions (failure reason, `stale` wording, and that neither ROADMAP.md nor STATE.md was mutated) are untouched. Verified against the real CLI: the emitted message is now "Phase 1 verification is incomplete: Verification is stale. Re-run verify-work before transition. Next: /gsd-verify-work 01".

Appending the phase number surfaced a trap the old bare commands hid. `extractPhaseToken` also returns project-code forms (`PROJ-07`), which are indistinguishable by shape from an ordinary directory name — `gsd-651-parent` yields `gsd-651` — so deriving the argument blindly emits `execute-phase gsd-651`. The number is therefore appended only when it is unambiguously numeric, or when the caller supplies it explicitly. `init` does supply it: its `phaseDir` is unresolved in several branches, where the router could not derive one at all. dir `01-example` -> $gsd-execute-phase 01, $gsd-verify-work 01 dir `gsd-651-parent` -> $gsd-execute-phase, $gsd-verify-work Suites verified green against the built lib: verification-status 50/50, phase 268/268, init 143/143, init-manager 40/40. `npm run lint:ci` clean. User-visible change beyond the reported bug, as agreed: `query verification.status` and `phase complete` now append the phase number for missing/unknown, and emit `verify-work <N>` for human_needed where they previously emitted nothing.

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.
