# Standard zero .05 now reserved for 'AI'

> I am claiming the reserved standard zero .05 for use by your AI agent.

[Standard zero](https://johnnydecimal.com/documentation/the-standard-zeros) `.05` has until now been reserved for expansion. I am claiming it for use by your AI agent. I'll duplicate the section from that page below.

## .05 AI

A place for your AI agent.

Agents work best when you write things down. Your JDex is an amazing communication tool: both you and your agent can read and write anything in it. Best memory ever.

Sometimes it's useful to have a _dedicated_ space that the agent controls. This is a place that it can store persistent information for recall across sessions.

You can also use it to provide per-system instructions to your agent. For example at `00.05` I have a 'style guide' that tells it how I like my frontmatter properties to be organised (alphabetically).

The [skills](https://johnnydecimal.com/jdhq/agent-skills) and [MCP server](https://johnnydecimal.com/jdhq/mcp-server) both assume they have control over `AC.05`.
