* fix: make punctuated CANONICAL_HEADERS synonyms reachable (audit M7)
classifyHeader received an already-normalized header (via normalizeAdrHeader,
which collapses [\s:._-]+ to a space and strips [^\w\s]) but compared it against
the RAW synonym strings. So any synonym carrying a hyphen/apostrophe ('trade-offs',
'non-goals', 'anti-goals', 'follow-up', 'cross-cuts', 'post-grilling', "how we'll
know", "won't do/have") could never match — its ADR section silently went unmapped.
Nine synonyms across six buckets were dead; the repo had characterization tests
pinning that quirk ('unreachable synonym').
Root-cause fix (per ADR-1372's 'compound, don't accrete' guidance): normalize BOTH
sides via a module-load-precomputed index, instead of pre-baking 9 normalized
literals into the data table. Closes the abstraction asymmetry once for all current
and future synonyms; the table stays human-readable. Also de-dupes 'trade-offs' from
considered_options so it no longer shadows risks once both normalize to 'trade offs'.
Insertion order preserved → first-match-wins + exact-then-prefix precedence byte-
identical for already-normalized synonyms; only the 9 dead synonyms gain matching.
Updates the 7 characterization tests to the corrected behavior and adds a
reachability+no-collision invariant test guarding the whole class against regression.
Note: the audit's M7 premise (trade-offs *misclassified into considered_options*)
was factually wrong — it was unmapped, and tested as such. adr-parser is CLI-only
(ADR-1372 T2), so the behavior change cannot reach in-process gates.

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.
