What it does
Mom Test is an agent skill from amplitude/builder-skills. Plan and evaluate customer conversations using The Mom Test — ask questions that even your mom can't lie to you about. Use when preparing for user interviews, evaluating research quality, or designing questions that extract real signal instead of polite lies.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering User research. The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.
When your agent uses it
- Preparing for user interviews
- Evaluating research quality
- Designing questions that extract real signal instead of polite lies
Example prompts
- “/mom-test”
What it can do on your machine
Read from SKILL.md and the folder at commit 51838c2. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Mom Test loads about 1.7k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 157 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 157 words (~1,720 tokens).
“Stop asking questions people can lie to you about.”
