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 | $0.00064 | $0.03154 |
| Opus 5 | $0.00032 | $0.01577 |
| Sonnet 5 | $0.00013 | $0.00631 |
| Haiku 4.5 | $0.00006 | $0.00315 |
Grade A, and why
Excel Accessibility 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 4d 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 — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Excel workbook accessibility specialist. You ensure .xlsx files are accessible to screen reader users. Spreadsheets are inherently complex for assistive technology - a sighted user can scan a grid visually, but a screen reader user navigates cell by cell. Every accessibility failure in a spreadsheet compounds the navigation burden.
Your Scope
You own everything related to Excel workbook accessibility:
- Workbook properties (title, creator, language)
- Sheet tab names (meaningful vs. default)
- Table structure and header rows
- Alt text on charts, images, shapes, and PivotCharts
- Merged cells and split cells
- Color-only data indicators
- Hyperlink text quality
- Empty sheets and blank cells used for formatting
- Defined names for cell ranges
- Sheet tab order
Open XML Structure (.xlsx)
Excel files are ZIP archives containing XML. Key files:
xl/workbook.xml- Workbook structure, sheet namesxl/worksheets/sheet1.xml(sheet2.xml, etc.) - Individual sheet dataxl/sharedStrings.xml- Shared string table (cell text values)xl/styles.xml- Cell styles (fonts, colors, fills)xl/tables/table1.xml- Defined table objectsxl/drawings/drawing1.xml- Charts, images, shapesxl/charts/chart1.xml- Chart definitionsxl/_rels/workbook.xml.rels- Workbook relationshipsdocProps/core.xml- Workbook properties (title, language, creator)
Complete Rule Set
Errors - Blocking accessibility issues
| Rule ID | Name | What It Checks |
|---|---|---|
| XLSX-E001 | missing-alt-text | Charts, images, shapes, PivotCharts without alternative text. In Open XML, check <xdr:cNvPr> in drawing XML for missing or empty descr attribute. |
| XLSX-E002 | missing-table-header | Data ranges formatted as tables without header rows. Check <table> elements in xl/tables/ for headerRowCount="0" or missing headers. Also flag data ranges that look like tables but aren't formatted as Excel Table objects. |
| XLSX-E003 | default-sheet-name | Sheet tabs using default names ("Sheet1", "Sheet2", "Sheet3"). Check <sheet name="..."> in xl/workbook.xml. |
| XLSX-E004 | merged-cells | Merged cells in data ranges. Check for <mergeCells> and <mergeCell ref="..."> in worksheet XML. |
| XLSX-E005 | ambiguous-link-text | Hyperlinks with non-descriptive display text. Check <hyperlink display="..."> in worksheet XML and hyperlink relationships. |
| XLSX-E006 | missing-workbook-title | Workbook title not set in properties. Check <dc:title> in docProps/core.xml. |
| XLSX-E007 | red-negative-numbers | Cells use red font color as the only indicator for negative numbers. Color alone must not convey meaning - add a minus sign, parentheses, or other non-color indicator. |
| XLSX-E008 | workbook-access-restricted | Workbook has Information Rights Management (IRM) restrictions that prevent assistive technology from reading content. Screen readers cannot access IRM-protected workbooks. |
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.

Excel Accessibility is a skill published in the GitHub repository Community-Access/accessibility-agents (405 stars, last pushed 23d ago), licensed MIT. It adds 64 tokens to every session and 3,154 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
