Per-surface verification loops for wenlan — daemon, cli, mcp, plugin, suite strength (mutation), behavior trace, weekly sweep. Routes to scripts; every check records evidence via attest. Deeper than the built-in verify skill — use prove for mutation audits, behavior tracing, and the weekly sweep; built-in /verify handles generic runtime observation.
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
# /prove [surface] — wenlan verification loops Run every check through the evidence wrapper (records to `.claude/attest.jsonl`, which the weekly sweep audits): `bash scripts/attest.sh <command>`. That wrapper ships in the repo and runs on macOS, Linux and Windows (Git Bash); the older `~/.claude/bin/attest.sh` is a personal copy that does not exist on every machine, and a missing wrapper means the run is unrecorded, which the sweep reads as "the smoke never ran". Sandboxed local runs need `TMPDIR=/tmp/claude` prefixed (macOS mktemp gotcha). | Surface | Command | Proves | |---|---|---| | `daemon` | read `references/daemon.md` | HTTP behavior on an isolated daemon | | `cli` | `attest.sh bash scripts/smoke-cli.sh` | shipped CLI black-box round-trip | | `mcp` | `attest.sh bash scripts/smoke-mcp.sh` | stdio JSON-RPC round-trip | | `plugin` | `/wenlan` setup verify path | plugin → MCP → daemon wiring | | `suite` | breadth: `cargo mutants -f <file>` (auto-generated mutants, lib-test oracle); depth: read `references/mutprove.md` | tests can actually go red (mutation audit) | …

How to install
mdr add 7xuanlu/wenlan/prove@sha256:0adda710d7d94417The line at the top of this page pins the label git:20261019.1b4e3ca, 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.
