f5-db

f5-db is a command for coding agents from Fujigo-Software/f5-framework-claude. It costs 4 tokens per session (1,076 once invoked), scanned A, original, MIT.

A database command set for viewing and changing a project's database. It supports common databases and the code libraries that connect applications to them.

In plain words
What is it for?
Viewing a database schema, creating or running migrations, undoing the latest migration, loading seed data, resetting a database, generating models, and creating relationship diagrams.
Why use it?
It keeps schema changes, test data, and database-related code in one workflow. It can also show how tables relate to each other in an entity-relationship diagram.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-db 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.

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.
