* chore(context): scrub nul byte from consent-store predicate
CONTEXT.md line 206 (Capability Consent Store predicate) contained a
literal NUL byte between ${realpath(projectRoot)} and <id> documenting
the disk-key join format. The byte was intentional but made the file
binary-detected, breaking grep/rg searches (hit while preparing ADR-1817).
Replace with the 4-char \x00 escape. Preserves the byte-level disk-key
documentation; surrounding prose 'prototype-pollution-safe NUL-joined
keys' carries the semantic context. file(1) now reports 'Unicode text'.
* docs(#1817): add adr-1817 state.md rebuild derivability contract
Phase 0 of approved feature #1817 (epic). Lands the design contract for
the new `rebuild` transition in the STATE.md Transition Module (ADR-1769):
- ADR-1817 (new): `rebuild` is the capstone 11th transition. Six design
decisions: (1) core substrate, non-toggleable, same tier as the other
10; (2) section taxonomy — re-derivable (`## Current Position` prose
from frontmatter, `## By-Phase Progress` table from disk) vs preserved
(`## Session`, `## Decisions`, unknown sections) vs de-duplicated
(`## Session Continuity Archive`); (3) orphaned data is logged + dropped
with a structured audit entry in `## Rebuild Log` (ADR-1411 provenance
principle); (4) idempotency is a hard guarantee — a no-mutation rebuild
appends no log entry; (5) non-overlapping scope with `sync` (3
frontmatter fields, auto-triggered); (6) orthogonal to
`auto_prune_state` (rebuild reconciles with current canonical sources,
prune removes by retention policy).
- CONTEXT.md (STATE.md Transition Module section): list `rebuild` as the
11th intent; add contract predicates mirroring the ADR.
- docs/adr/README.md: add ADR-1817 to the index (Accepted).
Targets the #1776/#1761/#1591 body-drift cluster that survived ADR-1769's
per-field transitions. Phased per ADR-1817: this PR (Phase 0) closes
#1817; Phase 1 (#1827) lands `rebuildCore` + intent dispatch + drift-class
unit tests; Phase 2 (#1826) lands `cmdStateRebuild` CLI + dry-run +
integration tests + docs + changeset.
* docs(#1817): reword state-doctor alternative to satisfy docs-parity lint
The docs-parity-live-registry test scans every docs/*.md (including
docs/adr/) for slash-command tokens and asserts each one resolves to a
live command in the registry. The rejected-alternative #4 in ADR-1817
mentioned a hypothetical `/gsd:state-doctor` workflow, which tripped
the lint (`unknown command token(s): [/gsd:state-doctor]`).
Reword to 'standalone state-doctor workflow' (no slash prefix). The
extractor is aggressive — backticks and space-preceding tokens are both
extracted per the test's own polarity-invariant cases — so the only
sound fix is to not form a slash token at all for hypothetical names.
Verified locally: `node --test tests/docs-parity-live-registry.test.cjs`
now passes 31/31 (was 30/1).
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.
