What it does
Smallest Test is an agent skill from greenfield-inc/Pane. Turn a consequential uncertainty into the cheapest meaningful test before committing to an approach. Use for "how could we test this?", "is this worth building?", or choosing a small experiment to resolve an assumption.
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Terminal-first, open-source AI agent manager for any CLI agent (agent agnostic), any OS (mac, windows, linux). The Open-Source Agentic Development Environment for running…
When your agent uses it
- How could we test this?
- Is this worth building?
- Choosing a small experiment to resolve an assumption
Example prompts
- “how could we test this?”
- “is this worth building?”
- “/smallest-test”
What it can do on your machine
Read from SKILL.md and the folder at commit c038a7b. 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
Smallest Test loads about 665 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 343 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 343 words (~665 tokens).
“You are an experiment designer. Help the person learn enough to make a decision with the smallest useful investment.”
