* enhancement(#558): add liveness hints to all GSD spawn announcements Append '(runs in a subagent — no output until it returns, ~1–5 min; expected, not a freeze)' inline to every ◆ Spawning… banner and subagent dispatch instruction across 26 workflows. Silent subagents look identical to frozen sessions — this note sets the expectation so users wait instead of killing healthy in-progress work. Changes: - references/ui-brand.md: document liveness convention under Spawning Indicators - 10 banner workflows: append liveness note to ◆ Spawning… lines in-place - 18 subagent-only workflows: add print instruction with liveness phrase - tests/spawn-liveness-banner.test.cjs: new test; fails if any workflow with subagent_type omits 'runs in a subagent' - docs/USER-GUIDE.md: troubleshooting entry for frozen-looking spawns - .changeset/558-spawn-liveness-banner.md: changeset fragment Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#558): add missing pr field to changeset fragment The changeset lint requires pr: <NNN> in frontmatter; the fragment was written without it, causing parse.cjs to reject it. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#558): address codex review — missed spawns and tighten test - plan-phase.md: add liveness note to chunked outline planner and per-plan chunked planner banners (two missed ◆ Spawning… lines) - quick.md: add liveness note to research banner and add missing display line before planner spawn in Step 5 - plan-review-convergence.md: add liveness note to initial planning and review-agent spawn Display lines - docs-update.md: add Print instructions with liveness note before gsd-doc-verifier spawns in Phase 1 and Phase 2 - autonomous.md: add Print instruction with liveness note before background plan-phase agent dispatch in step 3b - tests/spawn-liveness-banner.test.cjs: replace single file-level check with two assertions: (1) every ◆ Spawning… banner line carries the phrase on that line (2) every file with subagent_type contains the phrase somewhere The tighter test would have caught all five missed spawns. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#558): tighten spawn-liveness test regex to catch spawn-word-anywhere variants Previous SPAWN_BANNER_RE only matched ◆ immediately followed by Spawning|spawning. Replace with /◆[^\n]*\bspawning?\b/i which matches the spawn word anywhere on the ◆ line — catching "◆ Chunked mode: spawning outline planner..." and similar. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#558): rename changeset to PR number 566 and correct pr field Changeset was filed as 558-spawn-liveness-banner.md (issue#) but the convention is the PR number. Renamed to 566-spawn-liveness-banner.md and updated pr: 558 → pr: 566 so release notes link to the right PR.

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, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
Solves context rot — the quality degradation that happens as your AI fills its context window.
npx @opengsd/gsd-core@latest
Works on Mac, Windows, and Linux.
"If you know clearly what you want, this WILL build it for you. No bs."
"I've done SpecKit, OpenSpec and Taskmaster — this has produced the best results for me."
"By far the most powerful addition to my Claude Code. Nothing over-engineered. It just helps me ship."
Trusted by engineers at Amazon, Google, Shopify, and Webflow.

Returning to GSD Core?
Run
/gsd-map-codebaseto re-index your codebase, then/gsd-new-projectto rebuild GSD's planning context. Your code is fine — GSD just needs its context rebuilt. Use@opengsd/gsd-core@latestfor the current package line.
How It Works
The loop is six commands. Each one does exactly one thing.
1. Initialize
/gsd-new-project
Questions → research → requirements → roadmap. You approve it, then you're ready to build.
Already have code? Run
/gsd-map-codebasefirst. It analyzes your stack, architecture, and conventions so/gsd-new-projectasks the right questions.
2. Discuss
/gsd-discuss-phase 1
Your roadmap has a sentence per phase. That's not enough to build it the way you imagine it. Discuss captures your decisions before anything gets planned: layouts, API shapes, error handling, data structures — whatever gray areas exist for this specific phase.
The output feeds directly into research and planning. Skip it, get reasonable defaults. Use it, get your vision.
3. Plan
/gsd-plan-phase 1
Research → plan → verify, in a loop until the plans pass. Each plan is small enough to execute in a fresh context window.
4. Execute
/gsd-execute-phase 1
Plans run in parallel waves. Each executor gets a fresh 200k-token context. Each task gets its own atomic commit. Walk away, come back to completed work with a clean git history.
Your main context window stays at 30–40%. The work happens in the subagents.
5. Verify
/gsd-verify-work 1
Walk through what was built. Anything broken gets a diagnosed fix plan — ready for immediate re-execution. You don't debug manually; you just run execute again.
6. Repeat → Ship
/gsd-ship 1
/gsd-complete-milestone
/gsd-new-milestone
Loop discuss → plan → execute → verify → ship until the milestone is done. Then archive, tag, and start the next one fresh.
Getting Started
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Gemini CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally.
claude --dangerously-skip-permissions
GSD Core is built for frictionless automation. Skip-permissions is how it's intended to run.
Install only the skills you need with --profile=core (six core-loop skills), --profile=standard (core + phase management), or the default full install. Profiles compose: --profile=core,audit. --minimal is an alias for --profile=core. See docs/USER-GUIDE.md for the full walkthrough, non-interactive install flags for all 15 runtimes, and permissions configuration. See ADR-0011 for the profile model and runtime surface control.
The canonical release version is the @opengsd/gsd-core version published on npm and mirrored in package.json. Older release-note files under docs/ are retained as legacy continuity notes; do not use archived release-note numbers as the current GSD Core package version.
Cross-runtime compatibility: installer required
The agents/ and commands/ directories in this repository are Claude Code-format source files. The installer (npx @opengsd/gsd-core@latest) transforms them per target runtime — stripping or converting frontmatter fields that Claude Code uses but other runtimes reject. For example, OpenCode requires color as a hex or semantic value from a fixed set, and does not accept a tools: frontmatter field; the installer function convertClaudeToOpencodeFrontmatter (bin/install.js) handles this automatically.
Manually copying files from agents/ or commands/ directly into a non-Claude-Code runtime config directory (e.g., ~/.config/opencode/agents) skips the conversion step and will produce schema validation errors in that runtime.
If you are on a system without Node.js or npm (Windows + OpenCode is the most common case), see docs/USER-GUIDE.md — Manual install / no-Node.js setup for the per-runtime conversion summary and alternative install paths.

Why It Works
Three things most AI-coding setups get wrong:
1. Context bloat. As a session grows, quality degrades. GSD keeps your main context clean by doing the heavy work in fresh subagent contexts. Researchers, planners, and executors each start fresh with exactly what they need.
2. No shared memory. GSD maintains structured artifacts that survive session boundaries: PROJECT.md (vision), REQUIREMENTS.md (scope), ROADMAP.md (where you're going), STATE.md (current position and decisions), CONTEXT.md (per-phase implementation decisions). Every new session loads these and knows exactly where things stand.
3. No verification. Code that "runs" isn't code that "works." GSD's verify step walks you through what was built, diagnoses failures with dedicated debug agents, and generates fix plans before you declare a phase done.
See docs/ARCHITECTURE.md for how the multi-agent orchestration and context engineering work in detail.
Configuration
Settings live in .planning/config.json. Configure during /gsd-new-project or update with /gsd-settings.
Key dials:
| Setting | What it controls |
|---|---|
mode |
interactive (confirm each step) or yolo (auto-approve) |
| Model profiles | quality / balanced / budget — controls which model each agent uses |
workflow.research / plan_check / verifier |
Toggle the quality agents that add tokens and time |
parallelization.enabled |
Run independent plans simultaneously |
Optional structural review: set code_quality.fallow.enabled to true to add a fallow pre-pass to /gsd-code-review. GSD writes .planning/phases/<phase>/FALLOW.json and surfaces a Structural Findings (fallow) section in REVIEW.md. Install with npm install -D fallow@^2.70.0 (or system-wide via cargo install fallow; note that the Rust binary's JSON schema must match the documented v2.70+ contract — older versions may produce silent zero-finding output).
Package legitimacy checks are built into the research, planning, and execution path: recommended dependencies get audited, unverified packages require a human checkpoint, and failed installs stop instead of trying similarly named alternatives.

Troubleshooting
Commands not showing up? Restart your runtime after install. GSD installs to ~/.claude/skills/gsd-*/ (Claude Code), ~/.codex/skills/gsd-*/ (Codex), or the equivalent for your runtime.
Codex users — minimum supported CLI version is 0.130.0. Codex CLI 0.130.0 (release notes) removed extra-skill-roots discovery via openai/codex#21485; from that version onward Codex discovers skills from standard roots (including ~/.codex/skills/<name>/SKILL.md). GSD installs there directly. Earlier Codex CLI versions may still discover additional roots, which can surface duplicate gsd-* entries (one from extra-roots discovery, one from ~/.codex/skills/); restart Codex after install and either upgrade or accept the duplicate listing.
Something broken? Re-run the installer — it's idempotent:
npx @opengsd/gsd-core@latest
Containers or Docker? Set CLAUDE_CONFIG_DIR before installing to avoid tilde-expansion issues:
CLAUDE_CONFIG_DIR=/home/youruser/.claude npx @opengsd/gsd-core --global
