Use when a query needs direct SMT solving, an unsat core needs debugging, or another tool reports a solver timeout or unknown. Not for deciding what to prove: use proof-driven.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SMT solving with Z3 and cvc5 ## Contract | Field | Bound contract | |---|---| | Trigger | A constraint problem needs an SMT-LIB query written and solved, an `unsat` result needs its core explained, or a verifier built on Z3 or cvc5 (Apalache, Kani, Verus, Frama-C WP, Dafny, Why3) reports `unknown` or a timeout that must be diagnosed. | | Authority | Reversible local: writes `.smt2` files and solver logs; rollback is deleting them. No remote mutation. | | Side effect | Query files and captured solver output on disk. Solver runs are bounded by an explicit timeout. | | Done | Every query has a recorded verdict of `sat` with a model, `unsat` with a core, or `unknown` with the solver's reason and the change that resolves it. | ## Inputs …

How to install
mdr add outlinedriven/odin-claude-plugin/smt-solving-with-z3-cvc5@sha256:333700e9d41dd382The line at the top of this page pins the label git:20260912.6e06ed3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
