f5-classify

f5-classify is a command for coding agents from Fujigo-Software/f5-framework-claude. It costs 18 tokens per session (5,565 once invoked), scanned A, original, MIT.

A command that classifies input files by examining their contents, extracts structured information, and reports coverage, quality, limitations, and risks.

In plain words
What is it for?
Use it to review spreadsheets and documents, identify their types, detect gaps, declare what the inputs cover, and flag technical or content risks.
Why use it?
It helps reveal missing or poorly covered source material before later specification work, while leaving final decisions to a person.

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.

Security

Grade A, and why

f5-classify 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 4d 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.

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.
