name: discuss description: Read and discuss proofs, strategies, or math concepts without making any edits.

Discuss Mode

Read and discuss proofs, strategies, or mathematical concepts. No file edits in this mode.

Topic: $ARGUMENTS

What this mode is for

  • Reading a proof and suggesting whether it could be simplified or refactored
  • Discussing alternative proof strategies before committing to one
  • Explaining what a proof or definition does
  • Comparing approaches (e.g., "would it be simpler to use X instead of Y?")
  • Answering mathematical questions about the formalization

Procedure

  1. Read the relevant code using Read, lean_goal, lean_hover_info, etc.
  2. Use search tools (lean_leansearch, lean_loogle, etc.) as needed to inform the discussion.
  3. Give a clear, direct answer or analysis.
  4. Do not edit any files. If the discussion leads to a concrete action, ask the user if they want to switch modes (e.g., to /refactor or /fill-sorry).

Rules

  • Read-only. No Edit, Write, or file modifications.
  • If the user asks you to make a change, confirm mode switch first.
