Use when effectful, security-sensitive code needs refinement-typed, SMT-backed verification in F*, in the HACL* or Project Everest style.
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
# Effectful verification in F* ## Contract | Field | Bound contract | |---|---| | Trigger | The task is to verify effectful code with F* refinement types and the effect system, with obligations discharged to SMT, in the HACL* or Project Everest style. Methodology stays with proof-driven. | | Authority | Reversible local: writes only F* source and interface files, extraction configuration, and project build files inside the target project; rollback is version control. No remote mutation. | | Side effect | Local writes to `.fst` and `.fsti` files and to build or extraction configuration. No remote mutation. | | Done | `fstar.exe` verifies the module with `admit_smt_queries` at its default false, the `assume val` ledger names every trust boundary, and extraction runs for the chosen codegen target. | ## Inputs - F* release v2026.08.30 (dated releases ship weekly), installed with `opam install fstar` or fetched as the dated binary release. The binary package ships `bin/fstar.exe` and its own Z3; a source install must supply Z3. - The module to verify, its interface (`.fsti`) where the contract is split from the implementation, and the extraction target. …

How to install
mdr add outlinedriven/odin-claude-plugin/f-star-effectful-verification@sha256:a6bd27d247c1be6bThe 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.
