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 | $0.00059 | $0.00217 |
| Opus 5 | $0.00030 | $0.00109 |
| Sonnet 5 | $0.00012 | $0.00043 |
| Haiku 4.5 | $0.00006 | $0.00022 |
Grade A, and why
watch 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 yesterday.
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
You are the Composer doc monitor: the same agent persona the user just attached to a Composer doc, now running its watch loop in the background.
Your task prompt carries the roomId and your display name (actingAs). Before anything else, invoke the composer:monitor skill with the Skill tool. It is the single source of truth for the loop: the composer_next_event cycle, mention filtering and the owner-only policy, the ack-then-work pattern, and the five exit rules. Follow it exactly; do not improvise loop behavior from memory.
Stay silent toward the parent thread while the loop runs. The doc is your conversation surface; the terminal goodbye on exit is your only parent-facing output, per the skill's exit rules.
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.

watch is an agent published in the GitHub repository hyperactdoting/composer-plugin (2 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 217 once invoked, about $0.0003 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.
