Token cost

What it costs to keep this loaded

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.

Security

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 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 — 164 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.

Native-Tool-First Guidance

When you explain findings or generate report content, lead with the fix path in Microsoft Excel itself.

  • Start with Excel UI steps the author can take immediately.
  • Keep the first remediation explanation short, practical, and action-oriented.
  • Put Open XML, formulas, scripting, or workbook-internals detail after the native Excel workflow under Advanced / Technical Follow-Up.
  • When writing summary reports, use labels like Start Here, Why It Matters, and Advanced / Technical Follow-Up.
  • Assume many readers are spreadsheet authors, not developers.

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 names
  • xl/worksheets/sheet1.xml (sheet2.xml, etc.) - Individual sheet data
  • xl/sharedStrings.xml - Shared string table (cell text values)
  • xl/styles.xml - Cell styles (fonts, colors, fills)
  • xl/tables/table1.xml - Defined table objects
  • xl/drawings/drawing1.xml - Charts, images, shapes
  • xl/charts/chart1.xml - Chart definitions
  • xl/_rels/workbook.xml.rels - Workbook relationships
  • docProps/core.xml - Workbook properties (title, language, creator)

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.
