What is MinerU-Document-Explorer CLAUDE.md?

Instructions for MinerU Document Explorer, a knowledge-base system that indexes documents, searches them, reads them closely, and adds new information for AI agents. It includes command-line commands for managing document collections.

Using Bun to install and run the project, creating or managing collections, listing and retrieving documents, adding context, checking index status, updating collections, and generating embeddings for semantic search.

They provide the correct workflow and commands for finding documents and keeping their search index current.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03838	$0.03838
Opus 5.5	$0.01535	$0.01535
Sonnet 5.5	$0.00768	$0.00768
Haiku 4.5	$0.00384	$0.00384

Security

Grade A, and why

MinerU-Document-Explorer 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.
