office-excel

office-excel is a skill for Claude Code, Codex from Orkas-AI/Orkas. It costs 3 tokens per session (1,756 once invoked), scanned A, original, MIT.

A spreadsheet-workbook workflow that uses the built-in Office tools to read and create editable Excel files.

In plain words
What is it for?
Creating new .xlsx workbooks with multiple sheets, formulas, formatting, column widths, and editable charts, or reading existing workbook files.
Why use it?
It avoids adding separate Excel libraries when the bundled tools already cover the task, and keeps workbook creation in one supported path.

About the project

Orkas is a desktop application for commanding a team of AI agents through one chat, with a commander model assigning work to specialist agents in parallel or in sequence. People use it to coordinate research, writing, presentations, and software tasks while keeping files on their computer. The catalogue includes skills for extending the agents available to Orkas.

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

office-excel 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 11d 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.

Office Excel

Tool Route

Use the bundled Office tools as the default artifact path. Do not install OfficeCLI, pandas, or openpyxl when the built-in tools cover the task.

  • Use read_files with one paths item for a broad workbook read; use metadata_only:true when only prepared metadata is needed.
  • Use create_xlsx for a new .xlsx, including multiple sheets, live formulas, number formats, widths, common cell styling, and native editable charts in each sheet's charts array. Pass preview:false when the required office_review will provide the visual evidence.
  • Calling create_xlsx is mandatory for a supported new workbook. Bash or local code may prepare input rows or perform calculations that the tool cannot express, but must not construct, rewrite, or patch the final .xlsx package.
  • Call create_xlsx exactly once for one requested workbook. Include the complete initial workbook and chart plan in that call. If QA finds a correction, use office_read and edit_office on the exact returned path; a file created in this conversation is refined in place. Do not restart with a second create_xlsx, create a “可编辑” duplicate, or publish an intermediate workbook.
  • Use office_read mode:"get" with one targets array to batch-check representative formulas and computed/cached values; mode:"text" exposes displayed values, not formula definitions.
  • Use edit_office for .xlsx; it creates a separate working copy when the source was not already produced by this conversation.
  • After every create or edit, use office_review with action:"check_and_render" when visible layout matters, or action:"check" for structural-only validation. For a new workbook, reuse the sheet order supplied to create_xlsx; use office_read mode:"outline" when inspecting an existing workbook or after structural edits. Pass one-based worksheet positions in office_review.pages, never a worksheet name or cell range.

Artifact identity and convergence

  • Treat the artifact_path in the latest create/edit <office-artifact> receipt as the only current artifact identity. Pass that exact path verbatim to office_read, office_review, edit_office, and publish_outputs; do not reconstruct, shorten, or guess a path.
  • Batch all required worksheet pages into one review when possible. Do not repeat office_review for an unchanged artifact_revision and the same page set; a page that failed to render may be retried once by itself.
  • Continue editing only when the latest review identifies a concrete blocking defect and a targeted repair. Consolidate related repairs into one edit batch, then review the new revision. When structure is valid and only warnings or subjective polish remain, stop editing and publish.
  • If publish_outputs returns E_OUTPUT_NOT_PRODUCED, do not edit, review, or regenerate the workbook. Retry publication once with an exact eligible_current_turn_paths entry from the error. If no eligible path is returned or that retry fails, report the preserved artifact and the delivery blocker; never guess another path or claim publication succeeded.

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.
