Tom Boucher 9ade7926ca test(#3761): replace vacuous wave/files_modified gate with an anchored one (#3764)
The test 'planner has validation step or quality gate for wave/files_modified
consistency' asserted a six-token disjunction over whole-file substrings, five
of which occur ZERO times in agents/gsd-planner.md (validate_waves,
wave_validation, same wave — the last killing the entire quality-gate arm,
since that file has no quality_gate block). The sixth matched one incidental
pseudocode comment, so deleting the wave-ordering gate outright left the suite
green.

Per RULESET.TESTS.delete-bad-tests (CONTEXT.md:595) the vacuous test is DELETED
and replaced, not patched. The replacement anchors on the normative **Rule:**
sentence inside <step name="assign_waves"> — scoped to that step rather than to
the whole document, and requiring all four semantic clauses (wave scope,
files_modified subject, prohibition, overlap predicate) to hold within a single
sentence, so co-occurring words scattered across a paragraph do not pass.

agents/gsd-planner.md is unchanged: the anchor already exists there and survives
PR #3758's edits to the same region.

Teeth proven on the remote runner: a control commit paired these tests with a
deliberately gutted assign_waves step that retained the incidental phrase. The
new anchored test failed while the sibling test using the old predicate's
surviving arm stayed green — same input, opposite verdicts.

Fixes #3761

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:

  1. Discuss — capture implementation decisions before anything is planned
  2. Plan — research, decompose, and verify the plan fits a fresh context window
  3. Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
  4. Verify — walk through what was built; diagnose and fix before declaring done
  5. 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.
