* fix: recurse test discovery so subdir test suites actually run
scripts/run-tests.cjs discovered tests with a flat readdirSync(testDir),
silently excluding tests/observability/ (4 files), tests/dispatch/ (1) and
tests/installer-migrations/ (1) — 94 passing tests — from `npm test` and all
CI lanes. Walk the tree recursively (relative subpaths preserved), classify
suites by basename, and add a fail-on-zero-executed guard for suite/default
runs (escape hatch GSD_ALLOW_EMPTY_SUITE=1) while preserving the empty
--files/--files-from path the CI inert lane relies on.
Unit suite 735 -> 741 files; surfaces ADR-227's observability/dispatch seam.

* test: retire 5 verified-worthless tests
Adversarial verification confirmed these 5 prove nothing — their coverage is
provided more strictly elsewhere:
- enh-2790 'has a name: field' spot-checks (command-contract enforces /^gsd[:-]/)
- command-routing-hub duplicate construct + duplicate ERROR_KINDS assertions
- no-cjs-sdk-handsync-tooling (guarded files that never existed on main; bug-190
covers the real retired SDK artifacts)
- runtime-artifact-layout cline edge case (subsumed by the explicit-global test
and bug-782-cline-skills-emission)

* test: add ADR-218 release version-validation coverage
ADR-218 (reject leading-zero versions like 1.01.0; npm duplicate pre-check) had
zero tests — the logic lived only in release.yml bash. Add a test that extracts
the actual rejection regexes from the workflow and exercises them against a
boundary table (leading-zero/malformed rejected, valid accepted) plus structural
wiring assertions. Goes red if the regex is reverted to [0-9]+.

* test: redesign weak tests into behavioral, deterministic assertions
Per the ADR test audit, rewrite 27 weak test files (test-only, no source
changes) so each can go red for the defect it guards:
- kill pass-always assert.ok(true) placeholders (research-cli, worktree-baseref,
bug-260 security guard, eslint-rules x24, clusters '|| true')
- replace source-text grep with behavioral calls (install Kilo, sh-hook-paths,
plan-review-convergence) and add a repo-layout governance test
- de-flake real-clock/Math.random coupling (phase last_updated, bug-3707 mtime,
context-utilization property, feat-3594)
- fix independence/shared-state violations (bug-492 singleton, issue-844 tmpRoot,
core reapStaleTempFiles, active-workstream TTY, feat-488 GSD_HOME)
- strengthen property/shape-only tests (research-provider/store classification +
collision) and unconditional plugin.json schema validation (issue-766)
Verified: all 28 files run together 1220 pass / 0 fail / 1 skip.

* chore: add no-tautological-assert lint rule, error in test suite
New custom ESLint rule (eslint-rules/no-tautological-assert.cjs) bans asserts
that can never fail: assert(true)/assert.ok(<always-truthy literal>),
'cond || true' inside an assert, and equality asserts comparing two identical
literals. Wired as error on tests/**; full sweep confirmed zero existing
violations so the suite stays green. Prevents the placeholder-assert regressions
the audit redesigns just removed. RuleTester coverage added (6 valid, 8 invalid).
Note: no-only-tests was already enforced via eslint-plugin-no-only-tests, so no
duplicate rule was added.

* chore: gate new allow-test-rule exemptions to require an issue ref
ADR-456 requires any allow-test-rule exemption added after the ADR to carry a
tracking issue number, but nothing enforced it. New ratchet gate
(scripts/lint-allow-test-rule-refs.cjs, wired into lint:ci) fails when a NEW
allow-test-rule comment lacks a #NNN/URL reference; the 323 existing untracked
exemptions are grandfathered in an allowlist that ratchets down as they gain
refs. Red-green verified (novel untracked offender fails; compliant passes).

* docs: add ADR test-audit evidence report (#1192)
Full risk-first qa-test-architect audit of the ADR portfolio (37 ADRs + 4
platform lenses, adversarial verification of retire verdicts) that drove the
P0 discovery fix, ADR-218 coverage, 5 retires, 27 redesigns, and the two new
lint gates. Filed as point-in-time evidence under docs/issueevidence/, named
for tracking issue #1192.

* test: replace pre-existing raw NUL byte with escape in feat-3594 fixture
feat-3594's null-byte parser fixture contained a literal NUL byte (pre-existing
on next at b10e5681 — confirmed: base blob has 1 NUL, this fix has 0), which
made git treat the file as binary and would break grep/editors. Switch to the
\x00 escape; the runtime string value (a real NUL in the parser input) is
unchanged.

* test: address adversarial-review findings
Codex adversarial pass over the branch:
- capability-registry drift test no longer mutates the committed generated
capability-registry.cjs in place (concurrency hazard) — uses in-memory
checkPipeline comparison instead.
- allow-test-rule ratchet now detects exemptions in ALL comment forms (block
/* */ too, matching no-source-grep) so a block comment can't bypass it;
one newly-surfaced pre-existing offender grandfathered (323->324).
- install.test Kilo case asserts on what install(false,'kilo') actually writes
rather than manually calling configureKiloPermissions (masked the call site).
- issue-766 drops the undeclared transitive ajv dep for explicit structural
assertions from the schema fixture.
- adr-218 test notes the hotfix leading-zero gap is tracked in #1186.

* fix: address code-review findings (subdir discovery, rule + test gaps)
xhigh code review surfaced 15 confirmed issues, all fixed:
- run-tests.cjs --files now resolves subdir tests by bare basename + handles
Windows backslash paths (ambiguous basenames error clearly).
- affected-tests-lib.cjs listTestFiles made recursive — the targeted CI lane was
silently dropping changed subdir tests (same false-green class the audit fixed).
- no-tautological-assert now catches 'true || cond' and empty []/{} equality.
- verify-test-quality: restore provenance-classification coverage, tighten the
writeFile circular-detection check, guard the module-level file read.
- sh-hook-paths: cover the global-install .sh delegation branch (#2045 guard).
- active-workstream null-guard runs deterministically (no longer skipped on TTY).
- adr-218 structural guards tightened (major/minor leading-zero; needs: membership).
- repo-layout AGENTS.md guard no longer false-alarms on equivalent refactors.
- cross-ai ordering guard fails red when the step is missing.
- issue-766 parses required fields from the schema fixture (auto-enforced).

* test: stub USERPROFILE alongside HOME in feat-488 (Windows parity)
The feat-488 redesign stubbed process.env.HOME but not USERPROFILE; os.homedir()
resolves from USERPROFILE on Windows, so the home stub was not hermetic there —
caught by windows-test-parity-guard (stubsHomeNoUserProfile). Save/set/restore
USERPROFILE symmetrically with HOME (delete-if-originally-undefined).

* chore: reconcile allow-test-rule allowlist after rebase onto next
Rebasing onto current next pulled in merged PR #1170, which added
inventory-headings-countfree.test.cjs (a baseline allow-test-rule exemption) and
deleted inventory-counts.test.cjs. Grandfather the former and prune the latter so
the ratchet matches the merged tree. No new debt from this PR.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project
New here? Follow Your first project for a guided walkthrough from install to first shipped phase.

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.
