How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Testing Skill — Validation + Daily Health & Regression Intelligence

> **Convention:** see [conventions/quality.md](../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
  • `openclaw.plugin.json` keeps OpenClaw install-required native plugin fields

(`id`, object `configSchema`, and `contracts.contextEngines` when applicable)

  • 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 test/openclaw-plugin-manifest.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
