CLAUDE.md

blockdoc-python CLAUDE.md is an instructions file for Claude Code from berrydev-ai/blockdoc-python. It costs 207 tokens per session, scanned A, original, MIT.

A project guide for BlockDoc, a Python package for working with block-based documents and rendering them as HTML or Markdown.

In plain words
What is it for?
Use it when developing BlockDoc: install its development dependencies, run Ruff checks and formatting, run pytest tests, and navigate the package and test directories.
Why use it?
It puts the project’s setup, formatting, linting, testing, and code-style rules in one place, reducing guesswork when changing the code.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is berrydev-ai/blockdoc-python's own configuration. It tells Claude Code how to work on blockdoc-python itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything blockdoc-python configures →

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

blockdoc-python CLAUDE.md 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.

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.
