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

collibra-atlas AGENTS.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 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.

Collibra Atlas — Agent Guide

This file tells AI agents how to work effectively on this project.


Project in Brief

Collibra Atlas is a local-first AI knowledge layer for Collibra documentation exposed via two MCP servers:

  • collibra-fs — deterministic, ripgrep-backed filesystem server (verbatim citations).
  • collibra-rag — semantic search over a precomputed embedding bundle.

The bundle is built once by the maintainer, distributed via GitHub Releases, and consumed by end users with zero embedding work.

Language: Python 3.11+ · Package manager: uv · Test framework: pytest


Skill Catalog

The project ships skills under .agents/skills/. Most are available for the agent to invoke autonomously; a few are user-invoked only and must not be used unless the user explicitly names them.

Skill Invocation Purpose
atlas-creation model-invoked Build the dual MCP server system for any markdown corpus
collibra-docs-nav model-invoked Navigate Collibra developer docs, crawl llms.txt, clean GitBook syntax, plan Atlas build
web-browsing model-invoked Search the web and extract page content
code-review model-invoked Review diffs, PRs, and code changes
debugging model-invoked Diagnose test failures, crashes, unexpected behaviour
python-patterns model-invoked Pythonic idioms, type hints, best practices
python-testing model-invoked pytest, TDD, fixtures, mocking, parametrization
readme-writing model-invoked Create, rewrite, or audit README / documentation
agent-handoff model-invoked Compact conversation into a handoff document
embedding-strategies model-invoked Select and optimize embedding models for semantic search and RAG
eval-driven-dev model-invoked Set up eval-driven dev with pixie-qa for Python LLM apps
security-review model-invoked Security vulnerability scan for codebases — injection, auth, crypto, secrets, deps
skill-compliance model-invoked Audit skill compliance across 6 dimensions
skill-writing user-invoked Reference for writing/editing skills. Do not invoke unless the user explicitly names this skill.

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.
