Testing Skill — Validation + Daily Health & Regression Intelligence

Convention: see conventions/quality.md for the test-before-bulk pattern; this skill enforces it across the project's own test suite.

Two modes

This skill has two related but distinct modes:

1. Skill conformance validation — gbrain's own conformance bar (the original 1.0 scope). Validates every skill has SKILL.md with frontmatter, every reference exists, manifest + resolver coverage round-trips.

2. Project test-suite health (v0.25.1 extension) — runs the project's tiered test suite and produces a regression-classified report. Used by daily cron, container-restart bootstrap, and "how are the tests" prompts.

Pick the mode by trigger.

Mode 1: Skill conformance validation

Contract

This mode guarantees:

• Every skill directory has a SKILL.md file
• Every SKILL.md has valid YAML frontmatter (name, description)
• Every SKILL.md has required sections per test/skills-conformance.test.ts
• skills/manifest.json lists every skill directory
• skills/RESOLVER.md references every skill in the manifest
• openclaw.plugin.json skills[] round-trips with both
• No MECE violations (duplicate triggers across skills)

Phases

1. Walk skills directory. List all subdirs containing SKILL.md.
2. Validate frontmatter. Parse YAML, check required fields.
3. Validate sections. Check for the required headings.
4. Check manifest. Every skill dir must be in manifest.json.
5. Check resolver. Every manifest skill must have a RESOLVER row.
6. Check round-trip. RESOLVER trigger ↔ frontmatter triggers.
7. Report results.

Automation

bun test test/skills-conformance.test.ts test/resolver.test.ts

The CI-gated check is the package.json test script.

Mode 2: Project test-suite health (v0.25.1)

When to use

• Daily test cron fires
• User asks "run the tests" / "how are the tests" / "what's broken"
• After significant code changes (often via cross-modal-review)
• After container restart (bootstrap)
• When something seems off and you want to verify system health

Test tiers

Tier	What it runs	Wall time	Gates
Unit	bun test (deterministic, zero external calls)	<2s	Every commit
Evals	LLM-judge or quality evals	~60s	Daily
Integration	E2E tests against real Postgres	~5m	Pre-ship + nightly
System health	Disk / memory / CPU / service liveness	<10s	Daily

Daily run protocol

When the cron fires (or the user asks), do ALL of this:

1. Run unit tests

bun test 2>&1

Parse: total passed, total failed, total skipped, file-level results.

2. Run evals (if the project has an evals config)

# Adapt to the project's eval config
bun test --filter eval 2>&1

Parse: same format. Note any flakes (tests that fail due to API timeouts, not code bugs).

3. Run system health checks

• Disk / memory / CPU
• gbrain: gbrain doctor --fast --json
• Database connection (if applicable)
• Critical files exist (CLAUDE.md, AGENTS.md, etc.)

4. Git diff analysis (CRITICAL — regression intelligence)

# What changed since last test run?
git log --oneline --since="24 hours ago"

For each failing test:

1. Check if the test itself was modified recently (test change, not regression).
2. Check if the code it tests was modified recently (possible regression).
3. Check if it's a known flake (API timeout, service down).
4. Check if a dependency was updated (gbrain, bun, etc.).

5. Classify each failure

Classification	Marker	Action
REGRESSION — code changed, test broke	🔴	Flag with the commit that broke it
STALE — test expects old behavior; code is correct	🟡	Fix the test, not the code
FLAKE — API timeout, service down, LLM variance	⚠️	Note, don't alarm; retry once
NEW — test was just added and isn't passing yet	🟢	Check if intentional
INFRA — container restart wiped state	🛠	Run bootstrap, retest

6. Report format

🧪 Daily Tests — YYYY-MM-DD

Unit:   X/Y passed (Z skipped)
Evals:  X/Y passed
System: [health summary]

REGRESSIONS:
  🔴 <test-name>: broke by commit <sha> "<commit message>"

STALE TESTS:
  🟡 <test-name>: expects X but code now does Y (commit <sha>)

FLAKES:
  ⚠️ <test-name>: timeout (retry passed)

✅ ALL CLEAR  (when applicable)

7. Auto-fix protocol

DO auto-fix:

• Test expects an old file path after a rename → update the test
• Test expects an old version string → update
• Test expects a file that was intentionally deleted → remove the test
• Import path broke because file moved → fix the import

DO NOT auto-fix:

• Test expects behavior A but code now does B → ASK first. Maybe the test is right and the code has a bug.
• Security test failing → ALWAYS escalate, never auto-fix.
• Test was skipped with a TODO → don't un-skip without understanding why.

When uncertain: check the commit message that changed the code, check if there's a related PR or conversation, ask the user if still unclear.

State (regression history)

Track results in ~/.gbrain/test-state.json for trend tracking:

{
  "lastRun": "2026-04-16T13:37:00Z",
  "unit": { "passed": 1262, "failed": 31, "skipped": 8 },
  "evals": { "passed": 17, "failed": 0 },
  "system": { "doctor": "ok", "gbrain": "0.25.1" },
  "failureHistory": [
    { "test": "<name>", "since": "2026-04-14", "classification": "stale" }
  ]
}

This enables:

• Trend tracking (are we getting better or worse?)
• Flake detection (same test fails intermittently)
• Regression velocity (how fast do we break things after changes?)

Anti-Patterns

• ❌ Skipping conformance validation after adding a new skill
• ❌ Adding skills to manifest.json without adding to RESOLVER.md
• ❌ Treating every red test as a regression. Classify first; many are stale or flaky.
• ❌ Auto-un-skipping a test without understanding why it was skipped
• ❌ Auto-"fixing" a security test failure
• ❌ Reporting "all clear" without actually running system health checks

Contract

This skill guarantees:

• Routing matches the canonical triggers in the frontmatter.
• Output written under the directories listed in writes_to: (when applicable).
• Conventions referenced (quality.md, brain-first.md, _brain-filing-rules.md) are followed.
• Privacy contract preserved: no real names, no fork-specific filesystem path literals, no upstream-fork references.

The full behavior contract is documented in the body sections above; this section exists for the conformance test.

Output Format

The skill's output shape is documented inline in the body sections above (see "Output", "Brain page format", or equivalent). The literal section header here exists for the conformance test (test/skills-conformance.test.ts).
