* test(#3777): add failing-first coverage for concurrent per-plan planner dispatch Extracts and executes the real bash blocks this PR is about to add to plan-phase.md and chunked-planning-mode.md (CHUNKED_PARALLEL resolution and the BATCH_PLAN_IDS dedup guard), plus config-set/config-get coverage for the new planning.chunked_parallel key. Expected RED against the current shipped workflow text — the extraction anchors do not exist yet. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(#3777): dispatch chunked mode's per-plan planners concurrently within a Wave Adds opt-in planning.chunked_parallel (default false, byte-identical to the existing serial loop). When true and the runtime's negotiated dispatch capacity (dispatch-capacity, #3673) is greater than 1, chunked planning's per-plan Tasks that share one outline Wave are issued together instead of one at a time; a later Wave still waits for the current one to be verified on disk and committed. A host with no declared maxConcurrency (most non-Claude runtimes today) stays serial regardless of the setting. Resolution and the Plan-ID dedup guard live in chunked-planning-mode.md itself (gated on the section's own CHUNKED_MODE skip-check) rather than in plan-phase.md, so a non-chunked run pays no extra gsd_run calls. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#3777): repoint extraction at chunked-planning-mode.md after the move CHUNKED_PARALLEL resolution moved out of plan-phase.md into chunked-planning-mode.md itself (see the preceding commit); update the test's extraction path and header comment to match. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3777): relocate the canonical runtime-launcher preamble before its first use The CHUNKED_PARALLEL resolution block's two gsd_run calls landed earlier in the file than the sole existing preamble (in the commit step), which tests/runtime-launcher-parity.test.cjs's (B) check requires to precede every gsd_run call in the file. Move the preamble (not duplicate it) to the top of the resolution block; the commit step's fenced block now just calls gsd_run directly. Caught by the GREEN checkpoint gsd-test run before push. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3777): strip the canonical preamble from the extracted resolution block The CHUNKED_PARALLEL resolution fence now carries the relocated runtime-launcher preamble as its first line (previous commit). Extracting the whole fence and running it after the test's own gsd_run stub let the embedded preamble's own resolver logic `unset -f gsd_run` and exit 1 before reaching the resolution logic, since no real gsd-tools.cjs exists in the temp script dir — every test calling runChunkedParallelResolution() failed. Strip the preamble (sourced from gsd-core/workflows/_runtime-launcher.snippet.sh, the same file scripts/sync-runtime-launcher.cjs treats as canonical) before splicing in the stub, so this suite tests only the resolution logic it is actually about. Caught by the post-rebase gsd-test run before push. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * docs(#3777): add the How-To page the phase gate requires Enablement is 2 commands (config-set, then --chunked), which this repo's own doc-quadrant gate flags as how-to-owed: a reference table cannot carry a sequence. Covers enablement, the dispatch-capacity gate's honest "most runtimes today: no effect" case, and the two accepted trade-offs. An earlier reasoning pass (recorded in .gsd/phase/.../70-docs.json before this commit) had incorrectly claimed #3034 shipped with no equivalent how-to page, as precedent for skipping one here. That claim was false — docs/how-to/enable-parallel-reviewer-lanes.md exists and is indexed. The phase gate caught the omission before merge; corrected here.

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
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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.
