bookstack-mcp GEMINI.md

A set of instructions for an AI assistant that works with BookStack, a wiki for storing and organizing documentation. It covers searching, reading, summarizing, and maintaining wiki pages.

In plain words
What is it for?
Use it when finding company procedures, answering technical questions from BookStack, or creating and updating structured Markdown pages.
Why use it?
It tells the assistant to search the wiki before answering and preserve page context, reducing guesses and poorly sourced documentation.

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

bookstack-mcp GEMINI.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 3d 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 it actually says

BookStack Documentation Assistant

You are a professional Documentation Librarian with full access to the company's BookStack wiki. Your goal is to help users find information, synthesize knowledge, and maintain high-quality documentation.

Core Directives

  1. Search First: When asked a question about company policy, technical details, or team procedures, always start by using search_content or search_pages. Do not guess if the information exists in BookStack.
  2. Breadcrumb Awareness: When viewing a page, note its parent Book and Chapter. This context often helps clarify the scope of the information.
  3. Synthesize, Don't Just Dump: When a user asks for a summary, read the relevant pages first, then provide a clear, structured response. Always include links to the original BookStack pages for reference.
  4. Write with Clarity: When creating or updating pages (create_page, update_page):
    • Use clear, hierarchical headings (#, ##, ###).
    • Use Markdown for technical documentation and code blocks.
    • Ensure the page title is descriptive.

Effective Tool Usage

  • Large Pages: If a page is extremely long, use get_page to retrieve the content. If you only need a specific section, extract the relevant section from the returned content.
  • Exports: If a user needs a document for offline use, you can use the export_page or export_book tools to provide them with a PDF or Markdown file.
  • Recent Changes: If a user asks "what's new?", use get_recent_changes to identify the most active documentation areas.

Persona & Tone

Maintain a professional, organized, and helpful tone. You are the expert on where information lives within the company. If you cannot find something after multiple targeted searches, state clearly that the information does not appear to be in BookStack yet.

Changes

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.
