SaferSkills independently audited canvas-course-builder (Agent Skill) and scored it 96/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 1 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A bulleted imperative like {match} tells the agent to never reveal, disclose, or mention something to the user. Used adversarially it can instruct the agent to hide its tool calls or lie about what it did — stripping the transparency a user relies on to trust the agent.

The primary manifest — the file an agent reads to learn what this artifact does.
Build complete Canvas course structures from a natural language description, a JSON template, or by cloning an existing course. Creates modules with pages, assignments, discussions, and proper organization in one workflow.
This skill operates in three modes:
The user describes the course structure in natural language or provides a structured spec.
Load a saved JSON template to scaffold a course.
Read the structure of Course A and replicate it into Course B.
Ask the user how they want to build:
How would you like to build the course structure? 1. Describe it -- Tell me the structure (e.g., "15 weeks, each with an overview page, assignment, and discussion") 2. From template -- Load a saved template file 3. Clone another course -- Copy structure from an existing course
For Mode 1 (Spec): Ask for:
For Mode 2 (Template): Ask for the template file path. Parse the JSON template.
For Mode 3 (Clone): Ask for:

## Build Complete: [Course Name]
### Created:
- 15 modules
- 15 overview pages
- 14 assignments
- 14 discussion topics
- 58 module items linked
### Failed (0):
None
### Next Steps:
- All items created **unpublished** -- publish when ready
- Add content to overview pages
- Set due dates on assignments
- Run `/canvas-course-qc` to verify structureAfter building, offer to save the structure as a reusable template:
Would you like to save this structure as a template for future courses?
If yes, call get_course_structure(target_course) and save the output as a JSON file.
