What it does
Mo QA is an agent skill from aiskillstore/marketplace. Use Momentic's mo CLI to run and control Mo, Momentic's cloud autonomous QA agent. Use when starting or continuing Mo sessions, reading their output or status, stopping active work, answering Mo, or moving files between the local machine and Mo's hosted sandbox.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/authentication.md`, `references/installation.md` and `references/tunneling.md`).
It sits in Testing & QA. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Continuing Mo sessions
- Reading their output
- Stopping active work
- Moving files between the local machine and Mos hosted sandbox
Example prompts
- “s mo CLI to run and control Mo, Momentic”
- “/mo-qa”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Target URL: Include the exact path and query the change affects.
- Expected behavior: Explain what changed and what it should now do in
- Sign-in instructions: Name the login method and test account to use.
- Test data rules: State what Mo may create and what it must not touch.
- Out-of-bounds actions: Call out deletions, payments, emails, production
- Acceptance criteria: List the checks that decide pass or fail.
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
jq
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mo QA loads about 2.3k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 953 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 953 words (~2,292 tokens).
“Mo is Momentic's autonomous QA engineer. It runs in a hosted sandbox, where it can test web applications with a browser, inspect network traffic, run code and shell commands, delegate exploration, and report test cases and product bugs. Treat its…”
