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 5.1 | $0.00116 | $0.01728 |
| Opus 5.5 | $0.00046 | $0.00691 |
| Sonnet 5.5 | $0.00023 | $0.00346 |
| Haiku 4.5 | $0.00012 | $0.00173 |
Grade A, and why
create-announcement scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Weekly Canvas Announcement (GLOBAL, config-driven)
Generate the weekly Canvas announcement for a module — a friendly, beginner-facing "here's your week"
note. The email sibling of the agenda-wrapup skill: all three (Agenda, Wrap-up, Announcement) are
derived from the same module read, but this one sends email to every student, so it lives in its
own skill and is invoked deliberately — never automatically bundled with the pages.
Course coordinates are NEVER hardcoded. Read them from
course_config.load(<course_slug>):course_id,school,canvas_base_url,canvas_token_env. e.g.csci19a→ schoollpc, course58774, tokenLPC_CANVAS_TOKEN;cs110→ schoolavc, course69095. The user names thecourse_slug(or you infer it from the working directory); everything else comes from the config.
Step 1 — read the module ONCE (via canvas_rest)
Let base = cfg["canvas_base_url"], cid = cfg["course_id"], tok = canvas_token_auth.get_token(cfg["canvas_token_env"], base).
- Find the module:
cr.list_modules(base, tok, cid)→ match the week ([Week N],Week N), or the user gives the module id. A week can span multiple modules → collect all. - Items:
cr.get(base, tok, f"/courses/{cid}/modules/{mid}/items"). - Categorize by item
type+ SubHeader labels: Readings/Slides, Videos, Pages/guides, Assignments, Quizzes, Exams. - Due dates: Assignment →
cr.fetch_assignment(base, tok, cid, content_id).due_at; Quiz →cr.fetch_quiz(...).due_at. ALWAYScr.to_localtime(due)→ PDT/PST, never raw UTC. Null → "No due date set".
Step 2 — write the announcement (these parts, in order)
1. Friendly overview — "your week at a glance"
A kind, plain-English guide. Cover:
- a) Everything this week, summarized — what to read, what to watch, what to do, what to submit — all in one short scannable list.
- b) What you'll learn / the goal — what you learn this week, and what you'll be able to do by the end of the week (concrete outcome, motivating).
- c) Skill check — a short "can you do this now?" check at the end: if you can, that's the skill you gained this week. (Frame success as a checkpoint they can self-verify.)
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.

create-announcement is a skill published in the GitHub repository Canvas-LMS-MCP/canvas-teacher-mcp (1 stars, last pushed 2mo ago), licensed MIT. It adds 116 tokens to every session and 1,728 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.
