verify-cli-run SKILL.md skillA

verify-cli-run from reticlehq/reticle is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add reticlehq/reticle/verify-cli-run@v3.9.0

Pins v3.9.0 in mdr.lock. Pin the fingerprint instead.

Prove that a command-line tool actually did what it said, instead of trusting its exit code and its output. Snapshots the filesystem before and after, names the expected consequence in advance, and returns one of four verdicts with what could not be seen. Use after running a build, a migration, a scaffolder, a formatter, a codegen step, or an AI coding CLI; when a command printed success and you are about to report "done"; when you are about to write "exit code 0, so it worked"; or when a tool…

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 the command did what it said

A command exited 0 and printed `✓ done`. You have learned that the tool reached its own success branch. You have not learned that anything happened.

This is the whole problem with verifying a CLI: **the two things everybody checks are both the tool describing itself.** The exit code is chosen by the same code that did the work. The output is written by it. When a tool is wrong about what it did, it is wrong on both, in agreement. That is exactly why their agreement proves nothing.

This skill needs no tools installed. It is four rules and some `git`.

## The rule that decides everything

> **Evidence for a consequence must not come from the thing that performed the action.**

Grade every fact before you use it:

| What you have | Grade | Can it prove the command worked? |
| --- | --- | --- |
| Files on disk, before vs after | **consequence** | **Yes.** The filesystem decided whether the write landed, not the tool |
| An API answering when you ask it afterwards | **consequence** | **Yes.** Another party, answering you rather than the tool |
| Exit code | presence | No. The tool chose it |
| stdout / stderr | context | No. The tool wrote it |

How to install

The exact contents, by fingerprint
mdr add reticlehq/reticle/verify-cli-run@sha256:5255953535864553

The line at the top of this page pins the label v3.9.0, 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.
