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

convert-lakebook 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.

convert-lakebook

Convert Yuque .lakebook export files to clean Markdown documents.

What This Skill Does

  1. Extracts the .lakebook tar archive
  2. Parses $meta.json for document metadata (titles, ordering, dates)
  3. Converts each document's HTML body to clean Markdown using html2text
  4. Outputs individual .md files named by document title
  5. Generates an _index.md with a table of all documents

Prerequisites

pip install beautifulsoup4 html2text

Usage

When the user provides a .lakebook file path, run the conversion script:

python3 ~/Desktop/lakebook-converter/convert.py "<lakebook_file_path>" --output "<output_dir>"

Parameters

  • <lakebook_file_path>: Path to the .lakebook file (required)
  • <output_dir>: Output directory for Markdown files (optional, defaults to ~/Desktop/lakebook-converter/output/)

Default Behavior

If the user just says /convert-lakebook with no arguments:

  1. Ask the user for the .lakebook file path
  2. Ask where they want the output (suggest ~/Desktop/lakebook-converter/output/)
  3. Run the conversion
  4. Report results: how many docs converted, where they are, and show the index

Example Invocations

/convert-lakebook ~/Desktop/export.lakebook
/convert-lakebook ~/Downloads/my-notes.lakebook --output ~/Documents/notes/

Output Format

Each document becomes a Markdown file:

# Document Title

[converted content...]

An _index.md file is generated with:

# Document Index

Total: N documents

| # | Title | Words | Created |
|---|-------|-------|---------|
| 1 | [Title](filename.md) | 1234 | 2024-01-01 |

Error Handling

  • If dependencies are missing, prompt the user to install them
  • If the file doesn't exist, report the error clearly
  • If some documents fail to convert, report them but continue with the rest

Post-Conversion Tips

After conversion, suggest the user can:

  1. Use /extract-memory <output_dir> to analyze their writing style
  2. Read specific documents with the Read tool
  3. Search across documents with Grep
