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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00074 | $0.00359 |
| Opus 5 | $0.00037 | $0.00179 |
| Sonnet 5 | $0.00015 | $0.00072 |
| Haiku 4.5 | $0.00007 | $0.00036 |
Grade A, and why
canvas-discussion-catchup 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 11d 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
Discussion catch-up
Summarize a course's discussions so the student can post without reading every reply.
Steps
- Ask which course (or use the one in context); call
canvas_list_coursesif you need the id. - Call
canvas_list_discussionsfor that course to see the topics and which are active. - For the relevant topic(s), call
canvas_get_discussion_viewto get the full threaded replies. - Summarize the main points, points of agreement/disagreement, and whether a reply from the student is required (and by when — check the topic's due date via
canvas_get_assignmentif it's a graded discussion).
Output template
## <Discussion topic>
**The gist:** <2-3 sentence summary of where the conversation is>
**Main threads**
- <Person/theme>: <one line>
**Do you need to post?** <yes/no> — <requirement, e.g. "1 initial post + 2 replies by <date>">
**If you want to reply**, here are a few angles that haven't been covered yet:
- <angle 1>
Summarize faithfully — don't invent positions people didn't take. Never draft a post as if it's the student's own words unless they ask you to.
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.
