# Deedglass > Deedglass is the execution and accountability layer for AI agents. It sits between your agents and the tools they use: it decides what each agent may do, runs the action under control, checks the result against the system of record (L0 Reported, L1 Confirmed, L2 Witnessed by Postgres), and seals a signed deed anyone can verify offline. It is self-hosted, runs anywhere Postgres runs, and works with Claude, OpenAI, Gemini, Cursor and any MCP client. - Start with the Quickstart, then "What VERIFIED means" for the exact meaning of a verdict. - Every API error has its own page under /errors//. - Every feature page ends with "What it doesn't do". ## Documentation Sets - [Abridged documentation](https://docs.deedglass.com/llms-small.txt): a compact version of the documentation for Deedglass, with non-essential content removed - [Complete documentation](https://docs.deedglass.com/llms-full.txt): the full documentation for Deedglass ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation
