* fix(#2372): widen decision-coverage scan to planner-canonical tags, fix message Bug: check.decision-coverage-plan's remediation message told the user to cite decisions "(or body)" but extractPlanDesignatedSections only scanned <objective>/<tasks>/<task>/<action>. A decision cited in <read_first>, <behavior>, <verify>, <acceptance_criteria>, or <done> was invisible to the gate — false BLOCKING coverage gap, plus the message's own fix-hint sent the user to "the body" where re-citing still failed. Two-part fix (must change together — that drift was the bug): 1. Widen XML_DECISION_TAGS_RE in src/check-command-router.cts to also match <read_first>, <behavior>, <verify>, <acceptance_criteria>, <done>. These are all planner-canonical tags the planner is told to use (plan-phase.md:830-862, plan-phase.md:772). The body negative- lookahead mirrors the opening-tag set so each tag's body is captured independently. 2. Correct buildPlanMessage to name ONLY the surfaces the extractor actually scans (front-matter must_haves/truths/objective, designated markdown headings, and the nine planner-canonical tag bodies). The misleading "(or body)" clause is gone. Also updates the planner's documented contract (agents/gsd-planner.md:69) and user-facing docs (docs/CONFIGURATION.md, docs/USER-GUIDE.md) to reflect the wider scan. Regression tests in tests/decisions.test.cjs cover each newly-scanned tag body, a control (no citation still uncovered), and a message/extractor parity assertion that names every scanned surface — so the two cannot drift apart again. Out of scope (per triage): cmdDecisionCoverageVerify/buildVerifyMessage is a separate command (decision-coverage-verify) checking shipped artifacts, not plan citations — untouched. * chore(#2372): regenerate agent-size-baseline + golden-install-parity fixtures gsd-planner.md grew 49172 → 49294 (+122 chars) from the widened decision- coverage contract (5 new scanned tag names + heading clarification). Growth is justified: the contract surface is itself the fix — the prior text under-described what the gate scans, which was the bug. Updates: - tests/agent-size-baseline.json (gsd-planner.md: 49172 → 49294) - 17 tests/fixtures/golden-install-parity/*.json (one hash per runtime) - tests/fixtures/install-tree/*.json (regenerated by gen:golden) * fix(#2372): per-tag matching — outer-tag citations survive inner-tag nesting Code review (subagent) flagged a Medium edge-case regression from the single-alternation regex: when a newly-scanned tag nests inside another scanned tag, the alternation's negative lookahead halts the outer tag's body at the inner tag — losing any D-NN citation in the outer tag's prefix prose. Concretely: <action>per D-05 <verify>npm test</verify></action> → 3-tag alternation (old): captured 'per D-05 <verify>npm test</verify>' as <action> body → D-05 caught → 9-tag alternation (bug): captured 'npm test' only (from <verify>); D-05 in <action> prefix LOST Switches extractXmlTagBodies to per-tag matching: each tag gets its own regex whose negative-lookahead tempers only against the SAME tag's reopening. So <verify> inside <action> is absorbed into <action>'s body (D-05 caught) AND <verify> is matched separately on its own pass. Per-tag preserves both: - the reporter's case (sibling tags inside <read_first>) - nested-tag citations in outer-tag prefix prose - ReDoS safety (each per-tag regex keeps the #2128 body tempering) Also adds the reviewer's other requested edge-case tests: - non-scanned tag (<name>) bearing D-NN must NOT count - self-closing form <read_first /> safely ignored - attribute form <verify type="...">D-NN</verify> (canonical planner shape) - CRLF newlines in tag body do not break capture * chore(changeset): backfill pr:2443 in .changeset/noble-elks-chatter.md
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.
