* test(#2939): prove shouldFlattenDispatch ignores the depth budget Failing-first regression for #2939. shouldFlattenDispatch checks only background+backgroundDispatch, never nested/subagentToolkit/maxDepth, so a maxDepth:1 descriptor (no room for a bg orchestrator plus a leaf) is told it may background. Row 1 (codex-like, maxDepth:1) asserts true (flatten) and fails today; rows 2/3 guard the unchanged depth-sufficient cases. * fix(#2939): honor the declared depth budget in shouldFlattenDispatch shouldFlattenDispatch checked only background+backgroundDispatch, never nested/subagentToolkit/maxDepth, so a maxDepth:1 descriptor (no room for a backgrounded orchestrator plus a delegated leaf) was told it may background — producing a depth-2 tree (Codex MultiAgent V2) the declared contract cannot support. canBackground now ALSO requires nested:true + subagentToolkit:"full" + a depth budget > 1 (or unbounded -1), reusing the exact predicate shape from bin/install.js _normalizeDispatchCallSpan and matching degradationFor's treatment of maxDepth===1 as flat. Non-finite/missing maxDepth fails closed to flatten. Correct the two existing pins that asserted the buggy output (bare {bg,bgDispatch} now fail-closes on missing depth; the codex-like maxDepth:1 pin flips to flatten) and add a maxDepth:2 negative-space row. * fix(#2939): propagate depth-aware flatten to all pinned descriptors + tests The isolated adversarial review found the depth-aware predicate reclassifies codex/kimi/kimi-code (previously background-eligible under the two-field rule) to flatten — the correct behavior, since each lacks what a backgrounded nesting orchestrator needs: - codex: maxDepth:1 (no room for a depth-2 leaf) - kimi: nested:false (cannot host a nesting orchestrator) - kimi-code: subagentToolkit:'built-in-only' (cannot delegate to full subagents) Only cursor (maxDepth:2) remains background-eligible. Update the three test files that pinned the old contract (host-integration-descriptors EXPECTED_FLATTEN, kimi-upgrades UPGRADE 2, trae-imperative-reference), and align the unbounded convention to maxDepth < 0 (matching degradationFor/negotiateHostCapabilities) with an accurate docstring noting the deliberate nested-check addition over _normalizeDispatchCallSpan. * fix(#2939): update dispatch-should-flatten CLI query pins for codex The depth-aware rule (a0ad0f680) reclassifies codex (maxDepth:1) to flatten, but command-routing-hub.test.cjs exercises the contract through the CLI query route (runGsdTools query dispatch-should-flatten), not a direct shouldFlattenDispatch call — so neither the reviewer's caller-search nor a grep for the symbol found it; only the full gsd-test matrix did. Update the codex query assertions to shouldFlatten=true (maxDepth:1 insufficient), preserving cursor (maxDepth:2 → false) and the backgroundDispatch:true descriptor field. * chore(#2939): add changeset fragment pr:0 placeholder backfilled with the real PR number once the PR exists. * fix(#2939): rephrase changeset for product-name-purity + opencode flatten pin Two failures from the full gsd-test matrix on the prior sha: 1. product-name-purity: changeset fragments must not include parenthetical product descriptions (they render verbatim into CHANGELOG.md). 'Codex (and kimi/kimi-code)' tripped it — rephrase to lead with the behavior, naming runtimes inline without the parenthetical. lint:ci changeset-lint does not catch this; only the test does. 2. opencode-imperative-reference: the #2087-retraction pin flipped only the two background booleans and asserted shouldFlatten:false. Under #2939 that is no longer sufficient (opencode lacks nested + full toolkit + depth budget), so the retracted axes now correctly flatten — update the pin to true with rationale. * chore(#2939): backfill changeset PR number 3063 --------- Co-authored-by: sim <sim@local>

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.
