Do Check

Before you install that skill.

Found a skill in a post or a repository? Do Check reviews its instructions and code, explains potential concerns in plain language, and helps you decide what to do next.

01 / 03

Make it part of your toolkit.

Download the ZIP, extract it, and keep the whole do-check folder together. Choose your coding assistant below.

The bundled helper needs Python 3.10+ on macOS or Linux. Cisco has separate requirements and is optional. Its AI/cloud analyzers may need API access and incur charges; Do Check asks before enabling them.

01 / Download and extract

Download ZIP · v0.1.3

02 / Put the folder in place

Move the entire extracted do-check folder into your assistant’s skills folder. Create the skills folder if it does not exist. The SKILL.md file should then be here:

~/.agents/skills/do-check/SKILL.md
Official installation guide ↗

03 / Start a review

Open a new session in your coding assistant, then use this prompt with the link or folder you want reviewed.

$do-check Review this skill before I install it: [link or folder]

These instructions are for local Codex and Claude Code sessions. Cloud sessions and other AI apps may use a different installation flow.

What a review looks like

Illustrative example

Resolve these concerns first

This skill downloads and runs another script before it creates a chart. That script is not included, so its behavior could not be reviewed.

Evidence: SKILL.md, line 7

As a next step, ask for a fixed, reviewable version of the helper before running it.

A useful check. A clear scope.

Do Check reports what it examined and what it could not check. It cannot guarantee that a skill is safe or protect an unrestricted assistant from every prompt injection. Review findings before installing anything.

Package verification

Version 0.1.3 returned zero findings with Cisco Skill Scanner 2.3.2 core checks and the balanced policy on 10 November 2026. No custom suppressions were used. This result covers that configuration, not every possible attack.

Your current AI provider processes the material you submit. There is no Dueoptics telemetry or automatic report sharing. The ZIP includes the readable skill instructions, helper source, and MIT license.
