document-SKILLs: Instructions file for Codex

AGENTS.md

document-SKILLs AGENTS.md is an instructions file for Codex, OpenCode from appautomaton/document-SKILLs. It costs 1,249 tokens per session, scanned A, original, MIT.

A project instruction file for tools that create and edit PDF, PowerPoint, spreadsheet, and Word files. It explains how to run the included Python scripts and manage their packages.

In plain words
What is it for?
Use it when working on document-generation skills, including reading PDFs, extracting tables, processing images, creating PDFs, or editing office files.
Why use it?
It prevents agents from using the wrong Python installation or installing packages unsafely, and ensures scripts receive the dependencies they need.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is appautomaton/document-SKILLs's own configuration. It tells Codex and OpenCode how to work on document-SKILLs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything document-SKILLs configures →

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

document-SKILLs AGENTS.md 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 8d 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.

Document Skills

Skills for creating, reading, and manipulating PDF, PPTX, XLSX, and DOCX files.

CLAUDE.md in this directory is a symlink to this file (AGENTS.md).

Python

  • Always use uv run to execute Python scripts in these skills.
  • All directly-run scripts declare their dependencies via PEP 723 inline metadata — uv run resolves them automatically. (Library modules imported by those scripts inherit the runner's environment and need no header of their own.) No manual pip install needed.
  • When writing a new script, add a PEP 723 header:
    # /// script
    # requires-python = ">=3.12"
    # dependencies = ["pypdf", "Pillow"]
    # ///
    
  • Never run bare pip install. Never use the system Python (/usr/bin/python3).

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.
