pdf is agent-read markdown (skill) from usetemi/skills: Fill, redline, and generate PDFs with the right tool for the source. Detects AcroForm vs flat PDFs, handles AES-encrypted government forms, navigates appearance-stream gotchas, and verifies every output by rendering. Use when the user asks to fill a PDF form, redline a PDF, generate a PDF from markdown, or reproduce a packet of forms. PDF-only — DOCX, XLSX, and other formats are out of scope..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# PDF Mechanics
## Role
The mechanical layer for PDF work. Domain skills (legal, finance, regulatory packets) decide *what* the document should say. This skill decides *how* to produce it correctly. Domain skills delegate here rather than re-derive PDF mechanics each session.
**Scope:** PDF only. DOCX track-changes, XLSX, image manipulation belong in their own skills.
## First step: inspect, then choose path
```
SOURCE GOAL PATH
────── ──── ────
PDF (encrypted) anything decrypt first → re-inspect
PDF (AcroForm fields > 0) fill scripts/fill_acroform.py
PDF (AcroForm fields > 0) redline overlay onto AcroForm; fill is for values, not markup
PDF (flat, 0 fields) fill scripts/fill_overlay.py
PDF (flat, 0 fields) redline scripts/render_redlines.py
Markdown generate PDF scripts/markdown_to_pdf.py
```
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
