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 | $0.00144 | $0.05601 |
| Opus 5.5 | $0.00058 | $0.02240 |
| Sonnet 5.5 | $0.00029 | $0.01120 |
| Haiku 4.5 | $0.00014 | $0.00560 |
Grade A, and why
plan-assessment 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 — 413 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan Assessment
Plan a graded task (test, quiz, project, presentation, essay) and create the Canvas draft artifact describing it. Covers all 6 required slots of the school's assessment template. Generic across schools.
This skill never publishes anything. Assignments and pages land in Canvas as drafts (
published: false, enforced server-side). The teacher reviews in Canvas and clicks Publish themselves when ready. This is a hard policy — don't try to flip the published flag, don't ask the teacher whether to "create as a draft" (it's always a draft), and don't describe what the skill does as "publishing."
Assignment vs. page — which artifact?
Since canvas-mcp v0.4.1, create_assignment wraps its description in the school's page templates — so an assessment is normally created as one Canvas Assignment whose description carries the full assessment template (all 6 slots). That's the default: students see the assessment details on the assignment itself, where they submit.
Create a separate Page (create_page with template: "assessment") only when the teacher explicitly wants a standalone describing page (e.g., an in-class assessment with no Canvas submission, or their course convention keeps assessment pages separate from assignment objects).
When to use
A teacher describes a graded task that needs a Canvas artifact. Common phrasings:
- "Plan a 20-question quiz for DSGN 9 on the water cycle"
- "Create an assessment page for the prototyping project — 3 weeks, 25% of trimester"
- "I need an assessment for tomorrow's presentation day"
- "Draft a take-home essay assignment, 1500 words, due Friday"
The same template is used whether it's an in-class test or a long-term project — the slot content adapts.
When NOT to use
- Single lessons — that's
plan-lesson(UbD planning) orpost-lesson-page(posting an already-planned lesson). - The actual quiz object with questions inside — that's
post-quiz(it composes with this skill; see its "Linkage with plan-assessment" section). - Editing an existing assessment — see "Updating an existing assessment" below.
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-assessment is a skill published in the GitHub repository awesome-town/canvas-mcp-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 144 tokens to every session and 5,601 once invoked, about $0.0006 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.
