WHAT IT DOES

What axle_have2lemma does on Axle

AI agents invoke axle_have2lemma to trigger actions in Axle. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why axle_have2lemma needs a policy

Based on the sibling tools (axle_have2sorry, axle_normalize, axle_repair_proofs, etc.), this server executes transformations on Lean code via a remote API. The name 'have2lemma' suggests it transforms 'have' expressions into lemmas in Lean proofs — an Execute/Write-level transformation. Empty description lowers confidence.

From the tool's definition Tool name 'axle_have2lemma' on a server that runs Lean 4 proof engineering operations via a remote API. Description is empty.
