lean-counterexample

To find counterexamples in Lean before formal proofs, run the systematic counterexample checker on your Lean file. This validates conjectures early using plausible and decide tactics, reducing wasted proof effort on false statements.

The best way to validate Lean lemmas is systematic counterexample search before proof planning. This provides early risk assessment for theorem development by testing conjectures with rapid evaluation, avoiding wasted effort on false statements.

Yes, the counterexample checker integrates directly with Lean REPL, Scratch tests, and rapid evaluation using plausible and decide tactics. This workflow integration supports finite-type reasoning to test theorem candidates effectively.

You need to check for counterexamples in Lean theorem development before constructing formal proofs. Identifying counterexamples early guides proof planning and prevents investing effort in false conjectures during lemma validation.

Yes, you can use decide and plausible tactics for finite-type reasoning to test Lean theorem candidates. The counterexample checker supports rapid evaluation through REPL-based testing to validate conjectures before formal proof construction.

The systematic counterexample search for Lean proofs is limited to finite-type reasoning and quick evaluation. It focuses on early risk assessment for plausible and decide tactics, and may not cover complex infinite-type theorem domains.
