Ai Dev Tools Pr Radar Add Rule

Determine the following from the user's request or by asking:

• What to check for — the pattern, practice, or violation to detect
• Which files it applies to — file glob patterns like ["*.h"], ["*.swift", "*.m"]
• Evaluation mode — how violations should be detected:
  • AI (default) — Claude evaluates the diff against the rule's markdown content
  • Script — a shell script runs against the file and outputs violations
  • Regex — a simple regex pattern flags matches on changed lines

If the user describes something that can be checked deterministically (like "flag uses of X macro" or "check for missing Y annotation"), suggest script or regex mode since they're faster and fully deterministic. If the check requires judgment or understanding context, suggest AI mode.

Step 3: Choose the Subdirectory

Rules are organized into subdirectories within the rule path (e.g., apis-apple/, safety/, clarity/). List the existing subdirectories and either:

• Place the rule in an existing subdirectory that fits
• Create a new subdirectory if none fits
• Ask the user if it's unclear

Step 4: Create the Rule File

Write a .md file with YAML frontmatter and a markdown body.
