A framework for checking whether GBrain skills follow the project rules and for monitoring the health of its test suite. It covers unit tests, evaluation tests, integration tests, and broader system checks.

For validating skill files and manifests, running tests in stages, classifying failures, checking coverage, and comparing current failures with earlier test results.

It exposes missing skill files, invalid metadata, incomplete registrations, failing tests, and regressions in a structured report.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00063	$0.02034
Opus 5.5	$0.00025	$0.00814
Sonnet 5.5	$0.00013	$0.00407
Haiku 4.5	$0.00006	$0.00203

Security

Grade A, and why

testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to testing — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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:

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.
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

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

Automation

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

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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
