* refactor(#1387): migrate adr-parser onto markdown-sectionizer seam (T2) Replace hand-rolled parseSections (split/heading-regex walk/body accumulation) with collectSections(content, () => true) from the canonical seam. Replace hand-rolled splitEntries bullet-strip regex with iterateBullets from the seam, preserving the plain-text-line fallback for byte-identical output. Removes the last inline heading/bullet scanning from adr-parser.cts; normalizeAdrHeader and all ADR-specific classification logic are unchanged. 218/218 tests pass before and after. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(#1387): keep splitEntries flat (iterateBullets changed its contract); seam adoption stays in parseSections Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(#1387): drop dead preamble reconstruction; add targeted adr-parser mutation tests parseSections' preamble reconstruction block (heading: null entry) was dead code: both consumers (parseAdrMarkdown and parseStatusFromSections) skip heading: null sections immediately on entry. Confirmed via analytical trace and zero-diff corpus head-to-head across all 44 docs/adr/*.md files. Adds 11 targeted behavioral tests to kill cheap surviving mutants: - pushUnique intra-values dedup (kills seen.add removal mutant) - body split/join round-trip with multi-line prose and entries - parseStatusFromSections [0] indexing (only first line determines status) - classifyHeader equality vs prefix-match boundary (exact match, prefix match, synonym+letter non-match) - goal section prose vs entries distinction (bullet markers preserved in context) - normalizeAdrHeader non-word char removal (parens and slash behavior) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
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.
