* fix(#4379): make the TDD RED pathspec language-agnostic The pathspec IS this gate's definition of "a test file", and it listed only JS/TS conventions. Go's *_test.go matches none of them, so a commit adding a failing Go test was invisible, RED_COMMIT came back empty, and every behaviour-adding task halted with TDD GATE TRIPPED. references/tdd.md already advertises `go test ./...` and `cargo test` as supported, so the gate was refusing to see tests the docs promised to support. Two corrections, both measured against a seeded repo rather than reasoned: - cover the conventions tdd.md advertises: *_test.go, test_*.py, *_test.py, *_test.exs, *_spec.rb, *_test.rb. - drop the `**/` prefix. It does NOT match a path with no directory component, so a root-level foo.test.js was invisible even in the language the gate did support -- a second defect the report did not mention. A bare glob matches at every depth. Deliberately not widened to ordinary source: a pathspec matching implementation files would make the gate pass on any in-scope commit, which is worse than tripping wrongly. Rust is a known gap for that exact reason and is now documented rather than silently broken. Driving the shipped pathspec against a seeded repo: before, 0 of 7 language/root conventions matched; after, 7 of 7, with src/impl.go and src/lib.rs correctly unmatched in both. Emitted-Drift-Ack-Growth: execute-phase.md — the widened pathspec plus the comment recording why it must not cover ordinary source Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#4379): drive the shipped RED pathspec against a real repo The existing row pinned the pathspec as a literal string, which the fix makes stale. Re-point it, and add behavioural coverage that EXTRACTS the pathspec from the shipped workflow and runs git log with it against a seeded repo -- re-typing the pattern into the test would only assert that two copies of a string agree. Rows: every advertised convention is visible; a root-level test file is not invisible (the half the report missed); existing JS/TS still matches; implementation files never match, so the gate can still trip; and Rust inline #[test] stays out of reach, asserted rather than left silent. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#4379): add changeset fragment Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4379): be honest about the widened pathspec's cost Adversarial review: the rationale comment claimed the change was safe without naming what it gives up. `*.spec.*` can match a non-test file carrying the word (api.spec.json, openapi.spec.yaml), which lets the gate pass on a commit touching only that. Not new -- `**/*.spec.*` already matched those at any nested path, so dropping `**/` extends the same class to the root -- but the comment should say so rather than imply the widening is free. Also: the tdd.md list named Ruby and Elixir as recognised while the detection step above it enumerates only Node/Python/Go/Rust. Say explicitly that the gate's pathspec is wider than the detected project types, and why that is deliberate. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#4379): drop a vacuous row, fold its point into a real one Adversarial review: the "rust inline #[test] remains out of reach" row asserted src/lib.rs never matches -- the identical assertion to the "implementation files never match" row directly below it. It exercised nothing about #[test] semantics and would have passed against almost any fix, so it was coverage theatre. Delete it and move its rationale into the row that already carries the assertion, where it explains WHY the Rust gap follows from that row holding: the two cannot both be satisfied by a path-based gate. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4379): move the pathspec rationale out of a size-capped file execute-phase.md sits under a FROZEN byte ceiling (ADR-857 Phase 6, #1168: < 93600). The 20-line rationale comment I added pushed it to 93933 and tripped seven tests, all the same ceiling. Base was 92371, so the budget was 1229 bytes and the comment spent 1481. Keep six lines at the call site -- what the pathspec is, why it is not wider, where to read more -- and move the trade-off detail to references/tdd.md, which has no ceiling. That is the right home anyway: the workflow is loaded into context on every run, the reference is read on demand. 92882 bytes, 718 under. Pathspec line byte-identical; re-proved behaviour after the trim: 0/7 conventions before, 7/7 after, no implementation files matched either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#4379): refresh the compact-content benchmark baseline execute-phase.md changed size, so the committed baseline drifted. The script's own contract makes it a report that exits 0, but the test asserts the committed baseline is up to date -- refresh via --write, which is what the drift message instructs.

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.
