save-pdf-kb

save-pdf-kb is a skill for Codex from hraness/wrench. It costs 89 tokens per session (1,200 once invoked), scanned A, original, MIT.

A workflow for turning a PDF into a traceable Markdown knowledge-base bundle, including the original document, extracted text, page references, and available visual assets.

In plain words
What is it for?
Use it to import local or public PDFs, including scanned documents, into a knowledge base with capture details and OCR results.
Why use it?
It preserves where the imported information came from and makes the document easier to search and review.

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

save-pdf-kb 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Save a PDF to the knowledge base

Use the installed kb CLI. Resolve <vault> to the directory containing its authored or managed index.md front door, then set the shell-local KB_ROOT to that path (KB_ROOT=kb from a typical repository root).

Check the local conversion routes, then capture the PDF:

kb doctor
kb pdf "/absolute/path/to/document.pdf" --output "$KB_ROOT/articles"
kb pdf "https://example.com/document.pdf" --output "$KB_ROOT/articles"

Pass a stable slug or replace a prior tool-owned bundle only when needed:

kb pdf "/absolute/path/to/document.pdf" --slug ben-leaves-zo --output "$KB_ROOT/articles"
kb pdf "/absolute/path/to/document.pdf" --output "$KB_ROOT/articles" --force

The command installs one atomic bundle:

<slug>/
  <slug>.md
  capture.json
  source.pdf
  annotations.json  # present after a reviewed annotation pass
  assets/

source.pdf is the byte-identical input. The manifest records its original name, hash, byte count, page count, bounded document metadata, processed-page and block counts, image geometry, OCR status, and warnings without retaining the original absolute path. A reviewed second pass also retains the exact normalized annotation array as annotations.json; the manifest records its path, count, byte count, and SHA-256 so the image interpretation remains reproducible.

Preserve text and visual evidence

Treat native PDF text and image text as two independent extraction surfaces. Native text supplies layout, heading, link, and reading-order evidence. Local OCR supplies candidate text for scans and screenshots. Keep every extracted image as an asset even when its text is converted to Markdown.

For recognizable conversations, review the source image and turn OCR into readable message blocks with available platform, author, channel, and timestamp metadata. Preserve uncertain words explicitly instead of silently repairing them. Read references/review.md before refining screenshot-heavy or mixed-media PDFs.

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.
