* chore(#4603): retire the test-full CI job Phase 2 (#4591) added test-conformance but left test-full (the pre-existing full-suite Windows/macOS replay) running unchanged, gated on the same full_matrix flag, downgraded only from a hard gate to a non-blocking ::warning:: -- framed as "a non-gating safety net for one release cycle." No phase or issue ever retired it. Result: every full_matrix=true PR ran 10 OS-specific jobs (test-full's 6 + test-conformance's 4, purely additive) instead of the original 6 -- the epic's own goal (reduce runner-minutes) was measurably regressing, not improving, for the majority of PRs. This phase was missing from the original 4-phase epic decomposition; the epic (#4589) has been amended to add it as Phase 5 (see its comment thread), and this issue was filed as the tracked sub-issue. Deletes the test-full job from .github/workflows/test.yml entirely, along with every reference to it: required-tests' needs/FULL_TEST_RESULT warning branch, ci-timeout-report.cjs's JOB_RULES entry, ci-test-job-timeout-budget.test.cjs's LANE_COSTS/staticLanes/testFullRule entries, ci-test-scope.test.cjs's test-full-specific tests (preserving three unrelated tests that were nested in the same describe block, moved under a renamed describe rather than deleted), and docs mentions. test-conformance is now the sole gating signal for real-OS coverage. Two separate defects found and fixed while auditing every test-full reference: - tests/ci-pr-mergeability.test.cjs's GATED['test.yml'] safety-critical array (jobs that must needs: the mergeability preflight) had test-full but was missing test-conformance entirely -- Phase 2 never added it. Verified the real workflow wiring was already correct (test-conformance does have needs: [changes, preflight]); this was a test-coverage gap, not a live defect. Fixed by swapping the array entry. - docs/TESTING-SUITES.md's "## CI matrix" section was substantially stale independent of this phase (predating even #2952's coverage-gate split). Rewritten against the real, current job topology, verified directly against test.yml rather than trusted from memory. An isolated code-review pass found and fixed two minor inaccuracies in the rewritten docs table (two jobs' "Gated on" column didn't match their real if: condition exactly). An isolated security-review pass found no qualifying findings -- every compute-provisioning job already carries needs: preflight directly, unaffected by this deletion. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(ci): isolate 7 more heavy test files from chunk-weight packing `next`'s own push-triggered Tests run failed: `conformance test (windows-latest, 24, shard 2/3)` chunk 3/6 was killed after 600019ms. Root cause: state.test.cjs (weight 21.35, measured) was packed alongside companions by run-tests.cjs's LPT chunk packer, the same failure mode that previously hit codex-config.test.cjs (weight 17.87) twice and got a dedicated fix (ISOLATED_HEAVY_FILES, #4497) -- but state.test.cjs was never added to that set. This is a direct, unintended consequence of epic #4589 Phase 2: the new platform-conformance-tier job packs only ~546 files per shard (vs. the ~950-file full suite the packer used to balance against), so the same absolute-weight outlier now represents a larger share of a smaller, more homogeneous pool -- the LPT packer has fewer light files to pad around it with. This was a real, foreseeable side effect of shrinking the packing pool that nobody checked for when Phase 2 shipped. A first attempt at this fix hand-picked 4 candidates by eyeballing a truncated weight list and missed 3 heavier ones -- caught by an isolated code-review pass (blocker: emitted-attribution.test.cjs at 66.2% of the Windows chunk budget, install-minimal-hooks.test.cjs at 61.1%, install.test.cjs at 47.1%, all above codex-config.test.cjs's own 44.7% -- the ratio that already proved dangerous twice). Corrected by systematically computing weight/budget for every unit-suite file and isolating everything at or above that same ratio: 7 files total, plus the pre-existing codex-config.test.cjs (8 total). Added a durable regression test (tests/run-tests-harness.test.cjs) that re-derives this exact computation from the live tests/test-timings.json on every run, so a future heavy file crossing this threshold fails the test instead of silently reintroducing this failure -- not just a one-time manual sweep. Verified end-to-end: simulated the real 3-way windows shard split of the actual conformance-tier file list with the real packing functions. Max packable-chunk weight across all 3 shards is now 27.04 / 24.10 / 23.91 (shard 2 is the exact shard that failed on next), comfortably under the 40 budget -- versus 40+ and a 600s kill before this fix. A second isolated code-review + security-review pass on the corrected diff found nothing further.

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.
