* fix(#2911): resolve surface re-stage destinations the way the installer does Two writers computed the same destination differently. The installer honors a skills-kind home override; the surface re-stage ignored it and always resolved against configDir. For a global Codex install that override points at $HOME/.agents, so every re-stage built a second GSD-managed skill tree under $CODEX_HOME alongside the correct one, with nothing indicating which was live. Honors the override as a fallback, never a replacement -- runtimes without one still resolve against configDir, which is most of them. The real deliverable is the parity test, not the one-expression fix: it walks every runtime in the registry across both scopes, computes the installer and surface destinations, and fails naming the runtime if they ever disagree. Today only Codex global carries an override, so it discriminates on exactly one runtime -- stating that plainly rather than implying broader coverage -- but it is derived from the registry, so a newly-added runtime is covered without anyone remembering to add it. Two further defects fixed rather than deferred: - The legacy dev-preferences migration carried the identical defect, which the issue flagged as a latent instance of the same shape. - Fixing it exposed a symlink-escape guard confined against the wrong root: it checked the span between configDir and the skill dir, but a home override moves the skill dir outside configDir entirely, so the span was meaningless and threw a false-positive escape. Now confined against the install root the destination actually resolves under. The guard is unchanged in strength and still honors its opt-in; only the root it measures from is corrected. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2911): honor the home override in the fourth destination writer too Adversarial review found a writer the fix had missed: the opencode-family skills installer resolved its destination and its symlink guard against targetDir, never consulting the skills-kind home override, while its three siblings all already honored it. Pre-existing and currently dormant -- it is reachable only for the combined-family runtimes, and none of them declares an override today, so no user is affected right now. Fixed anyway rather than left as a latent instance of the same shape, which is exactly what this issue asked for in the case of the legacy migration. Mirrors the shape used for the other three: a single installRoot local that both the destination and the guard derive from, so the two cannot drift apart. The guard's message now names the root it actually confined against. Coverage extended to this writer and proven non-theatre: reverting the change in a scratch build makes it fail for both combined-family runtimes. Enumerated every remaining site that computes a destination from destSubpath or calls the confinement helper -- install and uninstall paths, the surface module, the read-side skills-root reporter. All honor the override or structurally cannot express one. No fifth defect. The one adjacent shape, the flat command directory, reads a different descriptor field that no kind declares an override for in the current schema; noted rather than papered over with a fallback for a field that cannot exist. Verified no behavior change for the affected runtimes today: normalized file-tree hashes before and after are identical.

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.
