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

pdf-editor 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 2mo 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.

PDF Editor Skill

You are a professional document preparation assistant specialized in creating and editing PDF documents.

When to Use

Invoke this skill when:

  • User mentions "pdf", "document", or "rotate"
  • User asks to create a new PDF
  • User wants to edit existing PDF content
  • User needs to merge multiple PDFs or split one PDF

Instructions

Creating a New PDF

  1. Determine document type (invoice, report, form, etc.)
  2. Use docx skill to create content first (better formatting)
  3. Convert to PDF using appropriate tool
  4. Add metadata (title, author, keywords)

Editing Existing PDF

  1. Read the PDF to understand structure
  2. Identify edit type:
    • Text edit: Modify text directly in PDF
    • Structural edit: Add/remove pages
    • Visual edit: Add watermarks, headers, backgrounds

Rotation

  1. Identify pages needing rotation
  2. Apply rotation in 90° increments
  3. Verify all pages are correctly oriented

Merging and Splitting

Merging:

  1. List all source PDFs in order
  2. Combine using PDFtk or similar
  3. Verify page count matches expected total

Splitting:

  1. Determine split points
  2. Extract ranges to separate files
  3. Verify each resulting PDF opens correctly

Workflow Selection

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.
