iRule Diff

Compare two iRule versions and analyse the differences.

Steps

1. Read the domain knowledge from ai/prompts/irules_system.md
2. Read both iRule files (the user should provide two file paths)
3. Run context analysis on both files:

   uv run --no-dev python ai/claude/tcl_ai.py context $FILE_A
   uv run --no-dev python ai/claude/tcl_ai.py context $FILE_B
   

4. If the analysis tool fails on either file, fall back to manual source comparison and note that LSP analysis was unavailable
5. Compare the two versions and explain:
   • Semantic changes -- What changed in behaviour (not just line diffs)?
   • Events -- Any events added, removed, or reordered?
   • Security implications -- Do the changes introduce or fix security issues?
   • Performance implications -- Any changes to hot-path efficiency?
   • Breaking changes -- Could these changes affect traffic handling?
6. If the user asked a specific question about the diff, focus on that

Output format

Focus on what matters operationally. Be concise. Use headings for each analysis section.
