Add an optional structured `coverage:` block to SUMMARY.md frontmatter and a deterministic classifier that `verify-work` consumes to route deliverables to auto-pass vs human-UAT — replacing the rejected #1598/#1599 post-hoc heuristic. - New `src/coverage.cts` (→ bin/lib/coverage.cjs) parses the nested coverage block (extractFrontmatter can't — its `-` items are scalars-only; this is a focused parser, sibling of parseMustHavesBlock), validates each entry, and classifies into auto_passed vs present. Frozen MODE/PRESENT_REASON/ERROR_CODE typed-IR surface. Exposed via `uat classify-coverage --summary <f>`. - Auto-pass is the narrow proven case only: strict-boolean human_judgment:false AND non-empty all-`pass` verification AND zero validation errors. Everything else — judgment, empty/failing verification, malformed entry — routes to the human (fail-safe). A malformed block falls back to legacy prose extraction and surfaces an error; an absent block is byte-identical to pre-#1602. - execute-plan create_summary populates the block (fail-safe default human_judgment:true); verify-work extract_tests consumes it; create_uat_file marks auto-passed entries `source: automated`. - Templates (summary + 3 variants), CONTEXT.md predicate + glossary, INVENTORY, eslint/gitignore registration, and Diataxis docs (COMMANDS reference + USER-GUIDE explanation) updated. - Behavioral tests via the CLI (no source-grep); parser-robustness regressions for the null-entry/comment-header/mis-indent cases found in adversarial review.

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.
