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 B, and why

squirrel-alerts scanned grade B with 2 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 9d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

What it actually says

Run this exact command with the Bash tool and show the user its output verbatim:

sh "${CLAUDE_PLUGIN_ROOT}/scripts/squirrel.sh" --alerts "$ARGUMENTS"

With no arguments it reports whether alerts are on, whether they fire while the terminal is focused, and which phases carry an action. test sends one notification immediately, and says which notifier it used — or that the machine has none.

To attach an action to a different phase, use /squirrel-phases:

  • set 300 notify=on — notify five minutes into a wait (the shipped default)
  • set 120 notify="Claude is stuck" — a phase with its own text
  • add 900 run="curl -d 'still waiting' ntfy.sh/your-topic" — anything else; run needs /squirrel-custom-commands on

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.
