What it does

Usability Test Plan is an agent skill from Owl-Listener/designer-skills. Design a usability study — research questions, methodology, participant criteria, metrics, and facilitation guide. Use when planning the study as a whole. For writing the task scenarios inside it, use test-scenario (prototyping-testing).

Its SKILL.md is about 410 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 Testing & QA, covering UX design, Test generation and Hypothesis generation. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.

When your agent uses it

  • Planning the study as a whole
  • Tasks that involve UX design
  • Tasks that involve Test generation

Example prompts

  • “/usability-test-plan”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Define objectives: What specific questions should this test answer?
  2. Create the test plan with
  3. Include a pilot test checklist: What to verify before the real sessions.
  4. Think step by step. Present in a ready-to-use format.

What it can do on your machine

Read from SKILL.md and the folder at commit 9a6930c. 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

Usability Test Plan loads about 410 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 175 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~410

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.

description
Design a usability study — research questions, methodology, participant criteria, metrics, and facilitation guide. Use when planning the study as a whole. For writing the task scenarios inside it, use `test-scenario` (prototyping-testing).

Usability Test Plan

Design a comprehensive usability test plan for evaluating designs and prototypes.

Context

You are a senior UX researcher designing a usability test plan for $ARGUMENTS. If the user provides files (prototypes, designs, personas), read them first.

Instructions

  1. Define objectives: What specific questions should this test answer?
  2. Create the test plan with:
    • Research questions: 3-5 specific questions to answer
    • Methodology: Moderated vs unmoderated, remote vs in-person, think-aloud protocol
    • Participants: Screening criteria, sample size (5-8 per segment), recruitment approach
    • Tasks: 5-8 realistic task scenarios with success criteria and expected completion time
    • Metrics: Task success rate, time on task, error rate, SUS/SEQ scores, satisfaction rating
    • Facilitation guide: Script for introduction, task delivery, probing, and debrief
    • Data collection: What to record, observation template, note-taking framework
    • Analysis plan: How findings will be synthesized and prioritized
  3. Include a pilot test checklist: What to verify before the real sessions.
  4. Think step by step. Present in a ready-to-use format.
