Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.00608 |
| Opus 5 | $0.00025 | $0.00304 |
| Sonnet 5 | $0.00010 | $0.00122 |
| Haiku 4.5 | $0.00005 | $0.00061 |
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 11d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
convert-lakebook
Convert Yuque .lakebook export files to clean Markdown documents.
What This Skill Does
- Extracts the
.lakebooktar archive - Parses
$meta.jsonfor document metadata (titles, ordering, dates) - Converts each document's HTML body to clean Markdown using
html2text - Outputs individual
.mdfiles named by document title - Generates an
_index.mdwith 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.lakebookfile (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:
- Ask the user for the
.lakebookfile path - Ask where they want the output (suggest
~/Desktop/lakebook-converter/output/) - Run the conversion
- 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:
- Use
/extract-memory <output_dir>to analyze their writing style - Read specific documents with the Read tool
- Search across documents with Grep
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.

convert-lakebook is a skill published in the GitHub repository anneheartrecord/charles-skill (3 stars, last pushed 1mo ago), licensed MIT.
