bounded-model-checking-c SKILL.md skillA

bounded-model-checking-c from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add outlinedriven/outline-driven-development/bounded-model-checking-c@git:20260912.5c5b759

Pins git:20260912.5c5b759 in mdr.lock. Pin the fingerprint instead.

Use when C or C++ code needs memory-safety or undefined-behavior guarantees proved with CBMC, or ACSL contracts checked with Frama-C Eva or WP. Not for choosing the proof policy: 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

# Bounded model checking C

## Contract

| Field | Bound contract |
|---|---|
| Trigger | A C or C++ function or module needs its memory safety, arithmetic, or user assertions checked exhaustively up to a bound (CBMC), its runtime errors bounded by abstract interpretation (Frama-C Eva), or its ACSL contracts proved deductively (Frama-C WP), or an existing run's trace or alarm must be read. |
| Authority | Reversible local: writes harness `.c` files, ACSL annotations in the source under analysis, and the tools' output directories; rollback is reverting those files. No remote mutation. |
| Side effect | Harness and annotated source on disk, CBMC GOTO binaries when `goto-cc` is used, WP proof-obligation files under `-wp-out`, and Frama-C session files when `-save` is used. |
| Done | Every property in scope is reported safe by CBMC under a recorded unwind bound, or has no Eva alarm, or is `Valid` under WP with a named prover, or has a trace or alarm mapped to a code defect and a fix. |

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/bounded-model-checking-c@sha256:b4e8e7287ae4c6ec

The line at the top of this page pins the label git:20260912.5c5b759, 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.
