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

Word DOCX Builder 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 yesterday.

The scan reads SKILL.md. This mod also ships 36 executable files (render_docx.py, scripts/a11y_audit.py, scripts/accept_tracked_changes.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Word DOCX Builder Skill (Read • Create • Edit • Redline • Comment)

Use this skill when you need to create or modify editable Microsoft Word .docx files in this container environment and verify them visually.

Tools + Contract

  • Use Codex workspace dependencies for docx artifact work: resolve them through the workspace dependency loader or runtime skill, then treat the returned Node/Python runtimes and package directory as authoritative. Do not use system node, system python, global npm packages, or repo-local installs.
  • For document creation and deterministic OOXML edits, it is still acceptable to use the bundled Python/OOXML helper scripts in this skill package when the JS surface is incomplete.
  • Run any builder or helper file from a writable workspace or temp directory, not from the managed dependency directory itself.
  • Final user-facing responses should describe only the requested document result and link only to the final .docx deliverable unless the user explicitly asks for QA intermediates.

Non-negotiable: render → inspect PNGs → iterate

You do not “know” a DOCX is satisfactory until you’ve rendered it and visually inspected page images. DOCX text extraction (or reading XML) will miss layout defects: clipping, overlap, missing glyphs, broken tables, spacing drift, and header/footer issues.

Shipping gate: before delivering any DOCX, you must:

  • Run render_docx.py to produce page-<N>.png images (optionally also a PDF with --emit_pdf)
  • Open the PNGs (100% zoom) and confirm every page is clean
  • If anything looks off, fix the DOCX and re-render (repeat until flawless)

If rendering fails because LibreOffice/soffice is missing, it is acceptable to return the requested DOCX without rendered PNG QA. In that fallback case, use the relevant Markdown task docs in this skill package as the authoritative guidance for building and checking the document structurally, state clearly in the final response that rendering/visual QA could not be completed, and do not imply that the document passed the render gate.

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.
