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

agent-broom 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 it actually says

Agent Broom

This skill is the memory hook. It exists so agents remember to run the CLI. The deterministic cleanup behavior lives in bin/agent-broom, bin/ports, bin/whoisonport, and lib/*.sh.

Start with the port checker surface when the user asks what is running or when a localhost port may be occupied:

bin/agent-broom ports --json
bin/agent-broom port <PORT> --json
bin/agent-broom ps --json

Run a dry-run audit first:

bin/agent-broom audit

Record long-running commands you start:

bin/agent-broom add --pid <PID> --kind dev --port <PORT> --purpose "<why>" -- <command>

Before ending the turn:

bin/agent-broom audit

Only act after reviewing the dry run:

bin/agent-broom kill <PORT|PID|RANGE>
bin/agent-broom kill --apply <PORT|PID|RANGE>
bin/agent-broom clean
bin/agent-broom clean --apply
bin/agent-broom stop --kill
bin/agent-broom artifacts --clean
bin/agent-broom devclean --apply

Never kill the editor, Codex, the user's shell, or shared MCP servers unless the script proves they are safe orphaned targets.

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.
