What is leo-system-health-check?

A system-maintenance workflow, with commands in English and German, for checking and tidying an agent setup. The description does not specify every maintenance action.

Use it for system health checks, updates, rebuilding an index, and cleaning inbox or archive areas when those actions are supported by the setup.

It groups routine checks and cleanup tasks that would otherwise need to be remembered and run separately.

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	$0.00118	$0.00264
Opus 5.5	$0.00047	$0.00106
Sonnet 5.5	$0.00024	$0.00053
Haiku 4.5	$0.00012	$0.00026

Security

Grade A, and why

leo-system-health-check 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 2mo 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.

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.
