* test(#2751): regression guard — no command-position bare gsd-tools calls Agents/workflows instructed bare `gsd-tools <verb>` invocations that fail with 'command not found' on a shim-only install (#725 fixed only the Codex conversion pipeline; the Claude-facing source shipped them verbatim). Adds a source-text guard (allow-test-rule: source-text-is-the-product) scanning agents/*.md + gsd-core/workflows/*.md for the operative shape `gsd-tools <verb> <arg>`, excluding command -v probes / resolver definitions, with a documented PROSE_ALLOWLIST for descriptive mentions that name the command without instructing literal invocation. A stale-allowlist check ensures entries stay real. RED first; source fix lands next commit. * fix(#2751): normalize bare gsd-tools calls to gsd_run in Claude-facing source The 12 command-position bare `gsd-tools <verb>` instructions across agents/ and gsd-core/workflows/ failed with 'command not found' on a shim-only install (no gsd-tools binary on PATH). #725 fixed this only for the Codex install-conversion pipeline; the Claude-facing SOURCE shipped the bare calls verbatim, and new ones kept accumulating (new-project.md:114 landed 12 days AFTER #725 closed). Rewrite each operative site to the portable `gsd_run` resolver that the same files already define (3-18x each) — a pure command-position token swap preserving all arguments, flags, --files, and surrounding prose. Every runtime now benefits from one source change instead of each needing its own converter. Touched sites (12): gsd-intel-updater (validate/snapshot/extract-exports), gsd-code-fixer (query commit), gsd-planner (learnings.query), gsd-project- researcher (websearch/research-plan/classify-confidence), gsd-phase-researcher (websearch/research-plan/classify-confidence), new-project (project-instruction- file / commit --files), new-milestone (commit --files). Preserves command -v gsd-tools probes, resolver-snippet definitions, and the 4 descriptive prose mentions that NAME the command without instructing invocation. RED @ 1bb12ba1. * chore(#2751): allow-test-rule issue ref + changeset fragment Add the (#2751) tracking ref to the source-text-is-the-product annotation per ADR-456, and the .changeset Fixed fragment (pr:0, backfilled post-PR). * fix(#2751): convert remaining command-position bare gsd-tools calls (verify-summary, windows, worktree, smart-entry, quick-tasks-append) Isolated adversarial review (Step 4) found the first pass missed genuine command-position bare calls because the regression test's hand-maintained 6-verb list silently false-passed verify-summary (the 'verify' branch matched the prefix then died on the hyphen) and omitted windows/worktree/smart-entry/ quick-tasks-append entirely. Convert these 8 additional operative sites across new-project.md, new-milestone.md, ship.md, execute-phase.md, progress.md, smart-entry.md, quick.md. * chore(#2751): backfill changeset PR number (2851) * fix(#2751): normalize allowlist paths to forward slashes — Windows path-separator false-flag The PROSE_ALLOWLIST is keyed by file:line using forward-slash paths, but path.relative() returns backslash separators on Windows, so the allowlist lookup failed and the 6 descriptive mentions were flagged as offenders on the windows-latest CI lane. Normalize rel to forward slashes before the lookup so the allowlist matches identically on every OS. --------- Co-authored-by: Test <test@example.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, 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.
