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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.04763 |
| Opus 5 | $0.00028 | $0.02381 |
| Sonnet 5 | $0.00011 | $0.00953 |
| Haiku 4.5 | $0.00006 | $0.00476 |
Grade A, and why
excel-live-control 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 today.
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 — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excel Live Control
Inspect, edit, analyze, format, and verify the workbook in the selected live Microsoft Excel session. Use connected-document tools for workbook reads and writes; use Computer Use only for application setup, target confirmation, and focus management.
On initial entry, complete the setup gates in order before session discovery. On follow-ups, reuse only the verified target and rediscover after workbook or add-in lifecycle changes.
Resolve every referenced file relative to this skill folder. Do not load the sibling artifact skill or its artifact-tool instructions while this live route is active.
Hard Routing Rules
Use this skill only when explicitly tagged or when the request clearly targets the Microsoft Excel desktop application, an open, active, or connected workbook in Excel Desktop, a selected range in Excel Desktop, the ChatGPT add-in for Excel, or a follow-up edit on the live-control path. For generic requests such as "create a spreadsheet," "create a workbook," or "create an Excel file" without explicit targeting of the Microsoft Excel desktop application or ChatGPT add-in, use the local workbook-authoring Spreadsheets skill instead. Stay on the live-control path unless the user explicitly switches targets; keep follow-up edits on the same path.
Routing selects the execution and delivery surface only; it does not override requested workbook content or a supplied reference/template.
Setup is part of the task. Use Computer Use only for setup checks and focus management, then use connected-document tools for workbook reads and writes. If a setup gate or required live capability is unavailable, stop and use the applicable exact guidance below. Do not silently switch to artifact authoring, open an unrelated workbook, or edit workbook cells through Computer Use.
Keep user-facing language to "Microsoft Excel", "ChatGPT add-in for Excel", "open workbook", "connected Excel session", or "live Excel control"; avoid internal connector/backend names.

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-live-control is a skill published in the GitHub repository rojim666/SztuCode (54 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 4,763 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.
Other skills, from other repositories
Gmail, Google Calendar, Drive, Docs, Sheets and Contacts for a connected Google account: read and search mail, send and reply, book and move meetings, find files, read and write Docs and Sheets, look people up. Use whenever the user mentions their email, inbox, calendar, meetings, Drive, a Google Doc or Sheet.
xlsx-official
Use this skill to build, edit, clean, or inspect a spreadsheet file (.xlsx, .xlsm, .xltx, .csv, or .tsv) when that file is the deliverable or the record being changed: financial and operating models, formula-driven summaries, template fills, cell and row patches, messy-data repair, sheet-to-CSV export, and workbook…
business-data-structuring
Inspect messy CSV/XLSX tables and create a reviewed clean business dataset with normalized headers, types, dates and amounts. Use for preparing a table; do not operate CRM entities or turn the preparation step into business analysis.
spreadsheet-analyst
Use when the user asks to inspect, clean, analyze, transform, calculate, or produce CSV or spreadsheet workbooks. Inspect sheets, schemas, formulas, and available spreadsheet tools first, preserve source data, and validate results with independent totals and rendered or structural checks.
feishu
Work with Feishu or Lark bots, docs, sheets, bitables, approval flows, and OpenAPI/MCP setup without hardcoding credentials.
xlsx
Create/edit/analyze/verify spreadsheet workbooks including XLSX/CSV/TSV.
