Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.00305 |
| Opus 5 | $0.00010 | $0.00152 |
| Sonnet 5 | $0.00004 | $0.00061 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
squirrel-phases scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Run this exact command with the Bash tool and show the user its output verbatim:
sh "${CLAUDE_PLUGIN_ROOT}/scripts/squirrel.sh" --phases "$ARGUMENTS"
With no arguments, this lists the current ladder. add <seconds> bg=<colour|off> [text=<colour|off>] [bold=on|off] adds a new phase; set <seconds> [bg=..] [text=..] [bold=..] overlays only the field(s) given onto the phase at that after value, leaving
everything else about it (and every other phase) untouched; remove <seconds> drops one
phase; reset discards all overrides and restores the shipped ladder. bold makes the
text colour bold (default false; both shipped phases ship true).
Never construct or write idlePhases JSON by hand — always go through this command (or
--show-phases/--add-phase/--set-phase/--remove-phase/--reset-phases), which edit one
phase at a time and never touch the others.
Do not do anything else.
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.

squirrel-phases is a command published in the GitHub repository kubalajiri/claude-squirrel (2 stars, last pushed 15d ago), licensed MIT. It adds 19 tokens to every session and 305 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
