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 | $0.00017 | $0.01654 |
| Opus 5 | $0.00009 | $0.00827 |
| Sonnet 5 | $0.00003 | $0.00331 |
| Haiku 4.5 | $0.00002 | $0.00165 |
Grade A, and why
peekaboo 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.
This is a copy
97% identical to peekaboo — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Peekaboo
Peekaboo is a full macOS UI automation CLI: capture/inspect screens, target UI
elements, drive input, and manage apps/windows/menus. Commands share a snapshot
cache and support --json/-j for scripting. Run peekaboo or
peekaboo <cmd> --help for flags; peekaboo --version prints build metadata.
Tip: run via polter peekaboo to ensure fresh builds.

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.

peekaboo is a skill published in the GitHub repository z80dev/lemon (129 stars, last pushed 3d ago), licensed MIT. It adds 17 tokens to every session and 1,654 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to peekaboo, differing in 4 lines, and is treated as a copy.
