Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00063 | $0.00605 |
| Opus 5 | $0.00032 | $0.00302 |
| Sonnet 5 | $0.00013 | $0.00121 |
| Haiku 4.5 | $0.00006 | $0.00060 |
Grade A, and why
nyann:fleet 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 2d 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.

Plugin root: This is a Claude Code plugin, NOT a CLI tool. Do NOT
search via which, npm list, pip list, or brew list. This file

/nyann:fleet
Wraps bin/fleet.sh (registry CRUD: --add/--remove/--list/--scan/
--prune/--suggest-org) and bin/fleet-doctor.sh (bulk audit +
dashboard). The registry lives at ~/.claude/nyann/fleet.json — LOCAL
working-copy paths, distinct from the sentinel watch-list (GitHub slugs);
an entry's optional repo slug joins the two (--watch mirrors it).
Dashboard default is a live per-repo doctor pass (worst-of exit codes
0/4/5); --cached reads persisted memory/health.json scores instantly
with staleness flags; --drift/--explain roll repo-tagged findings up
into one view. Registry scans and prunes preview first and only write with
--apply.

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.
