Agent body content should meet minimum length requirements

Warning Configurable

Rule Details ​

This rule checks that the markdown body of an agent file file (the content after frontmatter) contains enough substantive text. Very short body content typically indicates an incomplete agent definition that lacks the detailed instructions needed for effective agent behavior. The minimum length is configurable via the minLength option.

## System Prompt

You are a code review agent. Analyze pull requests for correctness, performance, and style issues. Provide actionable feedback with specific suggestions.

How To Fix ​

Add more detailed instructions, guidelines, or context to the agent body content. Include a System Prompt section with clear behavioral directives.

Options ​

Default options:

json
{
  "minLength": 50
}

Require at least 100 characters of body content:

json
{
  "agent-body-too-short": [
    "warn",
    {
      "minLength": 100
    }
  ]
}

Use a lower threshold for simple agents:

json
{
  "agent-body-too-short": [
    "warn",
    {
      "minLength": 30
    }
  ]
}

When Not To Use It ​

Disable this rule if your agents use an external system prompt source and the agent file body is intentionally minimal.
