Batch 13 of the ad hoc timeout literal migration (epic #4445). Replaces every bare numeric timeoutMs object-literal property in tests/task-content-resolution.test.cjs, tests/task-command-router-resolve-content.test.cjs, and tests/task-content-resolver-grammar-parity.test.cjs with a named constant, per eslint-rules/no-adhoc-timeout-literal.cjs. Removes these 3 files from the rule's allowlist. Every one of the 13 sites describes the same field -- a task-content- resolver manifest's invoke.timeoutMs -- as fixture/validation data; none is a real subprocess spawn timeout, verified by tracing each site to a pure function, a garbage-shape rejection path, or a fully-injected fake exec function. Adds one new shared constant, TASK_RESOLVER_INVOKE_TIMEOUT_MS, used by 2 files in this batch (crossing the promotion bar). Adds file-local constants for a value used by only 1 file, plus three deliberately-invalid values (zero, negative, non-integer) inside one findResolver garbage-shapes test proving the validator rejects a malformed manifest regardless of which way its timeout is invalid. Also fixes a review-caught defect outside the mechanical rule's own scope: a bare-literal duplicate of the new shared constant inside a ResolverTimeoutError assertion (a call argument, not an object-literal property, so the lint rule never flagged it) -- renamed in this same PR per the no-deferrals rule. No src/bin file touched, no numeric value changed anywhere. Co-authored-by: sim <sim@local> Co-authored-by: Claude Sonnet 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
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.
