A universal standard for AI-readable context about any resource.
Documentation: https://aitxt.ing
Specification: https://aitxt.ing/ai.txt
- Prevent AI hallucination — Tell AI assistants what you actually offer (and don't offer) so they stop making things up
- Plain text simplicity — Write an ai.txt file in minutes using prose and optional markdown; no schemas to learn
- Cascading discovery — Place ai.txt at any path; AI agents walk up the directory tree to find context automatically
- Distributed context graph — Link ai.txt files together using markdown; tools follow links ending in
ai.txt - Works everywhere — Same format for websites, project folders, APIs, documentation, local filesystems
- You control the narrative — Authoritative context comes from you, not AI training data assumptions
.claude/skills/aitxt/ is a /aitxt skill with a bundled discovery script. It works
automatically inside this repo; copy the directory to ~/.claude/skills/ to use it
everywhere:
cp -r .claude/skills/aitxt ~/.claude/skills/CC0 Public Domain
