patrol-on

patrol-on is a command for coding agents from cukas/patrol. It costs 20 tokens per session (118 once invoked), scanned A, original, MIT.

A session command that turns on Patrol’s strict checking for code changes. It requires investigation before edits and looks for quick fixes that may hide the real problem.

In plain words
What is it for?
Use it when you want a coding agent to investigate bugs before editing and check whether proposed fixes address the root cause.
Why use it?
It helps prevent changing code before understanding why it is wrong. It also flags temporary patches that could leave the underlying issue unresolved.

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

patrol-on 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 it actually says

Patrol On

Run this command to activate patrol mode:

SESSION_ID="${CLAUDE_SESSION_ID:-default}"
STATE_DIR="/tmp/patrol-${SESSION_ID}"
mkdir -p "$STATE_DIR" 2>/dev/null
echo "on" > "$STATE_DIR/mode"
echo "Patrol mode activated"

Tell the user: "Patrol mode ON. I'll now enforce investigation before edits and detect band-aid patterns."

Changes

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.
