f5-mode

f5-mode is a command for coding agents from Fujigo-Software/f5-framework-claude. It costs 4 tokens per session (2,452 once invoked), scanned A, original, MIT.

A command for switching how the coding agent behaves, such as coding, teaching, debugging, review, planning, security, or performance work.

In plain words
What is it for?
Use it to list available modes, inspect a mode, activate or reset one, check the current mode, and turn automatic mode detection on or off.
Why use it?
It avoids repeating instructions about the style of help you need. You can see, change, reset, or automatically select the current mode.

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-mode 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 5d 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.
