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 | $0.00121 | $0.03132 |
| Opus 5.5 | $0.00048 | $0.01253 |
| Sonnet 5.5 | $0.00024 | $0.00626 |
| Haiku 4.5 | $0.00012 | $0.00313 |
Grade A, and why
plan-lesson 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan Lesson
Think a single class session through using Understanding by Design (UbD) — start with what students should understand, design how you'll know they got there, then build the activities that get them there. Lesson-scaled: 1–2 learning targets, one formative check, one class arc. Produces a UbD brief in chat; offers handoff to post-lesson-page when the teacher's ready to materialize it on Canvas.
This skill writes nothing to Canvas. It's a pedagogical thinking partner. Posting is a separate skill (
post-lesson-page) the teacher can run once the brief is locked.
When to use
A teacher is figuring out what to teach for a single class session and wants a framework. Common phrasings:
-
"Plan a lesson on the water cycle for DSGN 9 — help me think through it"
-
"I'm teaching prototyping tomorrow, not sure how to structure it"
-
"Design a lesson on parallel circuits using UbD"
-
"What's a good way to frame this watershed lesson?"
-
"Help me think backwards from what I want students to understand"
When NOT to use
-
The teacher already knows what they're teaching and just wants it on Canvas. That's
post-lesson-page. Don't make them think backwards if they don't want to. -
Multi-class units or modules. That's
plan-module(which has its own UbD path scaled to multi-lesson arcs). -
Assessments / tests / projects. That's
plan-assessmentfor the page,post-quizfor the actual Canvas Quiz object. -
Whole-course scaffolding. That's
plan-course.
Prerequisites
-
canvas-mcp v0.3.16 or later installed if you want school defaults (class period length, current academic week) pulled via
get_school_info. The skill works without canvas-mcp for pure ideation, but will have to ask the teacher for period length and module context every time. -
No Canvas writes happen in this skill. No
published: falseworry, no draft creation — this is a chat-only working document.
Workflow
1. Establish context
Confirm with the teacher (asking only for what's missing):
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.

plan-lesson is a skill published in the GitHub repository awesome-town/canvas-mcp-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 121 tokens to every session and 3,132 once invoked, about $0.0005 per session on Opus 5.5. 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.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
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. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
