A post-restart health check for gbrain and OpenClaw, with automatic fixes for known problems.

Use it from the command line, startup scripts, or an agent to check runtimes, databases, workers, gateways, keys, and the brain repository.

It quickly shows whether essential services are working after a container restart and records any failures that remain.

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	$0.00052	$0.01420
Opus 5	$0.00026	$0.00710
Sonnet 5	$0.00010	$0.00284
Haiku 4.5	$0.00005	$0.00142

Security

Grade A, and why

smoke-test 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 9d 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

100% identical to smoke-test — 0 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.

How it starts

The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smoke Test Skillpack

Run gbrain smoke-test or bash scripts/smoke-test.sh after any container restart.

Contract

This skill guarantees:

8 core tests verify gbrain + OpenClaw health after restart
Known failures are auto-fixed before reporting
User-extensible via ~/.gbrain/smoke-tests.d/*.sh drop-in scripts
Results logged to /tmp/gbrain-smoke-test.log
Exit code = number of unfixed failures (0 = all pass)

Built-in Tests

#	Test	Auto-Fix
1	Bun runtime	Install from bun.sh
2	GBrain CLI loads	Reinstall deps
3	GBrain database (doctor)	—
4	GBrain worker process	Start worker
5	OpenClaw Codex plugin (Zod CJS)	`npm install zod@4 --force`
6	OpenClaw gateway	— (may not be started yet)
7	Embedding API key	— (check .env)
8	Brain repo exists	—

Usage

CLI

gbrain smoke-test

Direct

bash scripts/smoke-test.sh

From OpenClaw bootstrap

Add to your ensure-services.sh or equivalent:

bash /path/to/gbrain/scripts/smoke-test.sh >> /tmp/bootstrap.log 2>&1

From an agent

exec: bash /data/gbrain/scripts/smoke-test.sh

Adding Custom Tests

Create executable scripts in ~/.gbrain/smoke-tests.d/:

# ~/.gbrain/smoke-tests.d/check-redis.sh
#!/bin/bash
redis-cli ping | grep -q PONG

Rules:

Exit 0 = pass, non-zero = fail
Filename becomes the test name (e.g. check-redis from check-redis.sh)
Keep tests fast (< 10s each)
Tests run in alphabetical order

Adding Built-in Tests

Edit scripts/smoke-test.sh. Follow this pattern:

# ── N. [Service Name] ──────────────────────────────────────
if [test condition]; then
  pass "[Service Name]"
else
  # Auto-fix attempt
  [fix command]
  if [re-test condition]; then
    fixed "[What was fixed]"
    pass "[Service Name] (after fix)"
  else
    fail "[Service Name] — [error detail]"
  fi
fi

Design rules:

Test first — never fix without confirming broken
Re-test after fix — verify the fix worked
Timeout everything — timeout N on any command that could hang
Use helpers — pass(), fail(), fixed(), skip()
Idempotent fixes — safe to run repeatedly
Skip gracefully — skip() when a prerequisite is missing, don't fail

What this file has done since we first saw it

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.
