create-verification-skill

create-verification-skill is a skill for Claude Code, Codex from milind-soni/OpenMausBot. It costs 40 tokens per session (646 once invoked), scanned A, original, Apache-2.0.

A guide for creating a reviewed skill that launches, controls, and checks one specific app or project.

In plain words
What is it for?
Use it to inspect an app, run one real workflow, capture proof that it worked, and define safe cleanup.
Why use it?
It helps avoid unreliable verification instructions, invented commands, and testing against live user data.

About the project

OpenMausBot is an open-source chat application where users interact with multiple AI bots, each backed by an agent, model, computer, and connected apps. It is for people who want to run Claude, Codex, or Grok-based agents locally through a messaging-style interface. Its catalogue add-ons provide skills and instructions for working with the application.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-verification-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create a verification skill

Create one compact, project-specific SKILL.md through OpenMausBot's normal skill review flow. Do not install files directly, enable a skill yourself, or silently add scripts to the user's project.

1. Inspect before drafting

Use the tools already mounted on this bot to establish:

  • the exact project or app being verified;
  • its existing launch command and reliable ready signal;
  • the safest available control surface: existing project CLI, browser, computer, phone, or shell;
  • one read-only health check;
  • up to three important user workflows and the observable result that proves each one worked;
  • how to stop only the process or resource started by the verification run.

Prefer an existing control surface. If the project has no dependable way to launch or drive the relevant workflow, report that prerequisite instead of inventing commands, selectors, APIs, or a new control program.

2. Prove one workflow

Run the real launch, health check, one representative workflow, evidence capture, and cleanup once. Use an isolated test profile or temporary data when available; never drive the user's live data merely to author the skill. If the workflow cannot be proved with the tools currently mounted, stop and explain which capability is missing.

3. Draft one self-contained skill

The proposed SKILL.md must contain YAML frontmatter and these sections:

  1. Launch — exact command, isolated data/profile, ready signal.
  2. Doctor — one read-only check with an actionable failure message.
  3. Drive — stable names, accessibility targets, routes, refs, or commands; never recorded screen coordinates.
  4. Evidence — action plus resulting state and any important side effect.
  5. Cleanup — stop only what this run started; preserve the evidence.
  6. Feature map — at most three proven workflows, each with the user path, control recipe, success proof, and known gotcha.
  7. Maintenance — re-run Doctor and the affected workflow when the app changes; update drifted instructions but never hide a product failure.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
