Batch 16 of 17 in the ad hoc timeout literal migration (epic #4445). Replaces every bare numeric timeout/timeoutMs object-literal property in 9 test files with a named constant, per eslint-rules/no-adhoc-timeout-literal.cjs. No src/bin file touched, no numeric value changed anywhere. Ground truth via eslint found 48 sites, not the issue's stated 38 — tests/code-review.test.cjs alone has 11, not 1 (a 10-site undercount, the largest single-file drift in this epic). All 11 are migrated. Reuses PROBE_TIMEOUT_MS (17 sites across assumption-delta.test.cjs and code-review.test.cjs), LOOP_HOOK_POINT_CLI_TIMEOUT_MS (1 site), QUICK_SPAWN_TIMEOUT_MS (1 site). Adds a new shared constant, HTTP_REACHABLE_PROBE_TIMEOUT_FIXTURE_MS, promoted because two files (reviewer-manifest-body.test.cjs, reviewer-trust-disclosure.test.cjs) independently arrived at the same probe-fixture value across 3 sites. File-local constants elsewhere for values not shared across files: FALLOW_AUDIT_TIMEOUT_MS (code-review-pipeline-regression.test.cjs); a 5-constant set covering runBashScript's own override/forced-timeout/ boundary-triple tests (plan-phase-stall-detection.test.cjs); 9 lane-specific NATIVE_TIMEOUT_MS constants, one per shipped reviewer CLI tool, even where 4 lanes coincidentally share a value (review-lane-invocation.test.cjs); and a 6-constant set covering reviewer-manifest-body.test.cjs's own probe-kind fixtures and its separate, unrelated boundary/invalid set that coincidentally overlaps in shape (not value) with plan-phase-stall-detection.test.cjs's triple. Fixes applied inline from review: GENERATOR_SCRIPT_TIMEOUT_MS was misapplied to 3 sites in plan-review-convergence.test.cjs whose actual shape (nested bash -> node -> gsd-tools.cjs chain) doesn't match that constant's documented direct-spawn class, confirmed against its own cited precedent files — replaced with a new file-local constant naming the correct class, same value. Two stray un-renamed literals in review-lane-invocation.test.cjs (missed by eslint's object-literal-only detection) were investigated and left as disclosed literals with an explanatory comment rather than force-fit onto an unrelated lane's constant, since they belong to a distinct config-override code path.

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.
