Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an exemplar of a simple, single-purpose skill: concise, fully actionable with copy-paste commands and exact output formats, a clear setup-to-troubleshoot workflow with a validation checkpoint, and a clean one-level-deep split with the bundled script. No changes needed.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence — no padding explaining what Canvas or API tokens are — and every section (setup, usage, output format, troubleshooting) earns its place, matching the level-3 anchor.	3 / 3
Actionability	Provides fully executable, copy-paste-ready commands ('$CANVAS list_courses --enrollment-state active'), concrete curl examples with real headers, and exact JSON output schemas, satisfying the level-3 anchor.	3 / 3
Workflow Clarity	Setup is a clear numbered sequence with an explicit validation checkpoint ('verify auth by running $CANVAS list_courses — if it fails with 401...') and a troubleshooting table giving error-to-fix feedback loops, matching the level-3 anchor.	3 / 3
Progressive Disclosure	SKILL.md is a well-organized overview referencing a single real bundle file (scripts/canvas_api.py) that holds implementation detail — a clean one-level-deep split appropriate for a simple skill, matching the level-3 anchor.	3 / 3

Description

57%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific and clearly niched to Canvas LMS, but it omits any explicit 'when to use' trigger guidance and only lists two capabilities, leaving it at the middle tier for specificity and completeness. Adding a 'Use when...' clause and a few more natural trigger terms would lift the weaker dimensions.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when the user needs to see their Canvas courses, assignments, or due dates.'

Broaden trigger-term coverage with natural phrasings like 'homework', 'due dates', 'syllabus', or 'Canvas assignments'.

Mention one or two more concrete capabilities (e.g. filtering by enrollment state, ordering assignments by due date) to strengthen specificity.

Dimension	Reasoning	Score
Specificity	Names the Canvas LMS domain and two concrete actions ('fetch enrolled courses and assignments') plus auth method, but only two actions falls short of the 'multiple specific concrete actions' expected at level 3.	2 / 3
Completeness	It clearly states what the skill does, but there is no 'Use when...' or equivalent explicit trigger guidance for when Claude should invoke it, which per the guidelines caps completeness at 2.	2 / 3
Trigger Term Quality	'Canvas LMS', 'courses', and 'assignments' are natural user terms, but coverage stops there — common variations like 'homework', 'due dates', or 'syllabus' are missing, so it does not reach full level-3 coverage.	2 / 3
Distinctiveness Conflict Risk	'Canvas LMS integration' carves out a clear niche with distinct triggers (Canvas, courses, assignments) that are unlikely to overlap with other skills.	3 / 3
