1	# Canvas Accessibility Auditor
2
3	Full accessibility audit cycle for Learning Designers: scan course content, generate prioritized report, guide remediation of fixable issues, re-scan to verify fixes, produce compliance summary.
4
5	## Prerequisites
6
7	- Canvas MCP server must be running and connected.
8	- Authenticated user must have instructor, TA, or designer role in the target course.
9	- For UFIXIT integration: the course must have a UFIXIT report page (generated by your institution's accessibility tool).
10
11	## Steps
12
13	### 1. Identify Target Course
14
15	Ask the user which course to audit. Accept a course code, Canvas ID, or course name.
16
17	If not specified, prompt:
18
19	> Which course would you like to audit for accessibility?
20
21	### 2. Scan Course Content
22
23	Run two scans in parallel if possible:
24
25	Scan A -- Direct content scan:
26	```
27	scan_course_content_accessibility(course_identifier, "pages,assignments")
28	```
29
30	This checks all page and assignment HTML for:
31	- Images missing alt text (WCAG 1.1.1, Level A)
32	- Empty headings (WCAG 2.4.6, Level AA)
33	- Tables missing headers (WCAG 1.3.1, Level A)
34	- Non-descriptive link text like "click here" (WCAG 2.4.4, Level A)
35
36	Scan B -- UFIXIT report (if available):
37	```
38	fetch_ufixit_report(course_identifier)
39	```
40
41	If the UFIXIT page exists, parse it:
42	```
43	parse_ufixit_violations(report_json)
44	```
45
46	### 3. Generate Prioritized Report
47
48	Combine results from both scans. Call `format_accessibility_summary` if using UFIXIT data.
49
50	Present issues sorted by priority:
51
52	```
53	## Accessibility Audit: [Course Name]
54
55	### Summary
56	- Content scanned: 20 pages, 15 assignments
57	- Total issues: 12

82	- PDF accessibility: Cannot be parsed via API (use Adobe Acrobat checker)
83	```
84
85	### 4. Guided Remediation
86
87	For each auto-fixable issue, walk the user through the fix:
88
89	For missing alt text:
90	1. Call `get_page_content(course_identifier, page_url)` to retrieve the HTML
91	2. Identify the `<img>` tags without alt attributes
92	3. Ask the user for alt text descriptions (or suggest based on surrounding context)
93	4. Call `edit_page_content(course_identifier, page_url, new_content)` with corrected HTML
94
95	For non-descriptive links:
96	1. Retrieve the page content
97	2. Show the current link: `<a href="...">click here</a>`
98	3. Suggest descriptive replacement: `<a href="...">Download the syllabus (PDF)</a>`
99	4. Apply fix after user approval
100
101	For empty headings:
102	1. Retrieve the page content
103	2. Show the empty heading
104	3. Ask: "Remove this heading, or add text to it?"
105	4. Apply the chosen fix
106
107	For tables missing headers:
108	1. Retrieve the page content
109	2. Show the table structure
110	3. Ask: "Which row/column should be headers?"
111	4. Convert `<td>` to `<th>` elements and apply
112
113	Always ask for user confirmation before modifying any page.
114
115	### 5. Re-scan Modified Pages
116
117	After remediation, re-run the scan on modified pages only:
118
119	```
120	scan_course_content_accessibility(course_identifier, "pages")
121	```
122
123	Report: "Fixed 8/12 issues. 4 remaining require manual review."
124
125	### 6. Generate Compliance Summary
126
127	Produce a final summary suitable for stakeholder reporting:
128
129	```
130	## Accessibility Compliance Summary
131
132	Course: [Course Name]
133	Audit Date: [date]
134	Auditor: AI-assisted audit via Canvas MCP
