* fix(#1012): invoke fallow with its real CLI and wire the report normalizer The /gsd-code-review structural pre-pass invoked fallow with flags no published fallow version accepts (--json, --profile, --stdin-files), so it failed on every run and degraded silently per REQ-FALLOW-02 — the feature never delivered on any fallow version. Three compounding defects: 1. Invalid flags. Real fallow audit uses --format json (not --json), -q/--quiet, --changed-since/--base for changed-files scoping (no file-list input), and --max-crap for thresholds. There is no --profile or --stdin-files. 2. Exit-code handling. fallow audit exits 1 when it FINDS issues (verdict=fail), 0 when clean. The pre-pass treated any non-zero exit as a crash and discarded the output — i.e. it threw away exactly the findings it exists to surface. Success is now decided by whether a valid fallow JSON report was produced, not by the exit code. 3. Schema mismatch. normalizeFallowReport parsed a fictional top-level schema (unusedExports/duplicates/circularDependencies) fallow never shipped, and was dead code (the workflow embedded raw JSON; its tests asserted the fictional schema, one even calling a non-existent runFallowAudit and passing vacuously). Fixes: align the invocation to fallow's documented agent-facing pattern; map the profile preset (minimal/standard/strict) to --max-crap (50/30/15); scope phase runs via --changed-since with a repo-scope fallback; rewrite the normalizer to fallow's real schema (dead_code.unused_exports/unused_files/circular_dependencies + duplication.clone_groups) and wire it into the workflow so the reviewer receives normalized findings; replace the fictional-schema fixtures and tests with real-schema ones and delete the vacuous runFallowAudit test.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
