Fix Invalid llms.txt Format

llms.txt has a simple format: key-value pairs and sections. Invalid syntax prevents AI systems from parsing it.

Common causes

  • Invalid key-value format (missing colon, wrong encoding).
  • Broken UTF-8 or BOM issues.
  • Inconsistent line endings.

How to fix

  1. Use Key: value format, one per line.
  2. Ensure UTF-8 encoding, no BOM.
  3. Validate with llms.txt Validator.
