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 | $0.00017 | $0.00287 |
| Opus 5 | $0.00009 | $0.00143 |
| Sonnet 5 | $0.00003 | $0.00057 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
squirrel-sessions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Run this exact command with the Bash tool and show the user its output verbatim (as a code block, so the columns line up):
sh "${CLAUDE_PLUGIN_ROOT}/scripts/squirrel.sh" --show-sessions "${CLAUDE_SESSION_ID} $ARGUMENTS"
The table sheds columns to fit the terminal rather than wrapping — ten columns need about 130
of them. session and 5h pts are never dropped, since they are the question the table
answers: which session, and how much of the shared 5-hour window it has taken. When anything
is hidden the table says so and names the missing columns.
If the user wants everything regardless of width, pass wide (they may say "show me
everything" or "the full table") — the output will wrap, which is their choice to make.
Read the 5h pts marks out when explaining the table: no mark means exact, ~ means
estimated (the window was shared, or part of it is a gap), ? means nothing could be
attributed yet. Those marks stay on the figure at every width, so a number never reads as
more certain than it is.
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-sessions is a command published in the GitHub repository kubalajiri/claude-squirrel (2 stars, last pushed 14d ago), licensed MIT. It adds 17 tokens to every session and 287 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.
