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 5.1 | $0.00017 | $0.00347 |
| Opus 5.5 | $0.00007 | $0.00139 |
| Sonnet 5.5 | $0.00003 | $0.00069 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
office-recalculate 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 2d 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.
This is a copy
100% identical to office-recalculate — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Recalculate spreadsheet formulas
Use the installed LibreOffice Kit CLI through the shell with the absolute Node and CLI paths supplied below. In Bash, invoke "<node>" "<cli>"; in PowerShell, invoke & "<node>" "<cli>". Prefer bundled LibreOffice unless the user requests another installation. If the Office sidecar is missing, follow sidecar setup: ask whether the user wants to download it and install only after they agree. Do not invoke system soffice, use npx, or install a replacement to work around a failed recalculation with an installed sidecar.
Keep the original workbook and write a new file in the task workspace. Quote each input and output path.
"<node>" "<cli>" recalculate --input <workbook.xlsx> --output <recalculated.xlsx>
Verify the saved result with openpyxl, using load_workspace_dependencies for the Python path unless a project environment is required. Open it with both data_only=False and data_only=True. Check that formulas survive and cached results match the requested logic, expected totals, and cell types. Check required unchanged sheets, styles, and data. Recalculation does not validate business logic or guarantee Excel-specific feature compatibility.
If no supported recalculation engine is available or the command fails, preserve the workbook and explain that calculated values could not be refreshed. Do not replace requested formulas with constants or present stale/absent caches as fresh results. Deliver the verified output through present when available, keeping the file in place.
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.
