Phase 3 of epic #4636, stage 3b. Satisfies #4653's criterion that `opts.allowAbsolute` become "a named acceptance policy on the predicate, not a per-call-site boolean". The flag was actively misleading at the call site. `{ allowAbsolute: true }` reads as "containment is relaxed here". It never was: an absolute path that resolves outside the root is rejected exactly as a traversal is. The flag only ever controlled whether an absolute candidate was CONSIDERED. On a security predicate that is the wrong thing for a reviewer to have to infer, and 31 call sites were asking them to infer it. PathAcceptance.RelativeOnly relative candidates only PathAcceptance.AbsoluteInsideRoot absolute accepted, containment unchanged The three exported wrappers take the policy and translate it inward. validatePath keeps its internal `{ allowAbsolute }` opts and its body untouched — the engine is not re-derived here either, only the exported surface is renamed. MEASURED, NOT ESTIMATED. 31 call sites across 10 files, counted by walking the AST with the repo's own @typescript-eslint/parser rather than grepping: a text match would have folded in the options-type declaration, default parameter values and comments. All 31 pass the literal `true`; none passes `false` or a dynamic value, so the migration is uniform and `RelativeOnly` is purely the existing default made nameable. audit.cts alone holds 18 of them. This migration is compiler-verified in a way the containment-value migration in the previous commit was not: the parameter type changed from an object to a string union, so any missed site is a build error rather than a silent behavioral difference. That is why a 31-site mechanical edit is acceptable in the phase whose stated risk is the width of mechanical change. Co-Authored-By: Claude Opus 5 <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, 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

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.
