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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00095 | $0.01118 |
| Opus 5.5 | $0.00038 | $0.00447 |
| Sonnet 5.5 | $0.00019 | $0.00224 |
| Haiku 4.5 | $0.00010 | $0.00112 |
Grade A, and why
excel-analyst-pro 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.

A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
What ships with it
11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

sheet-authoring
Technical reference for writing open-sheet workbooks — the file contract, the component surface, references and formulas, number formats, and the rules that keep a workbook a live model. Use this whenever writing or editing a file under sheets/ /index.tsx. The workflow for drafting a new workbook from scratch lives in…
apply-comments
Use this skill when the user has left notes on cells in the open-sheet viewer and wants them applied — "apply my comments", "do the notes I left", "I marked some things up". Walks every @sheet-comment marker in the workbook source, makes the edit each one asks for, and clears the marker.
create-theme
Use this skill when the user wants a reusable house style for open-sheet workbooks — "make a theme with our brand colours", "all our spreadsheets should look like this", "create a corporate template". Writes themes/ .md and an optional demo workbook the gallery previews.
current-sheet
Use this skill to find out which workbook, sheet, and cell the user is currently looking at in the open-sheet viewer, so an instruction like "make this bold" or "why is this wrong?" resolves to the right place without asking. Use it whenever the user refers to "this cell", "this sheet", "the one I'm looking at", or…
