What it does

Usability Testing is an agent skill from Owl-Listener/designpowers. Use when planning or conducting usability tests — writing test scripts, defining tasks, selecting participants, analysing findings, and turning observations into design actions

Its SKILL.md is about 710 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 and UX design. The repository describes itself as: An agent design team you control: 10 agents that run an inclusive design process while you direct. The licence is MIT.

When your agent uses it

  • Conducting usability tests — writing test scripts
  • Selecting participants
  • Analysing findings
  • Turning observations into design actions

Example prompts

  • “/usability-testing”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Define What You're Testing
  2. Select Participants
  3. Choose Method
  4. Write the Test Script
  5. Analyse Findings
  6. Turn Findings Into Actions

What it can do on your machine

Read from SKILL.md and the folder at commit cb00757. 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 Testing loads about 710 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 357 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~710

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.

Usability Testing

Testing with real people is how you find out if the design works — not by looking at it, but by watching someone use it.

When to Use

  • After design-builder produces a working prototype
  • Before declaring a design complete
  • When the design-critic flags persona coverage gaps
  • When assumptions about user behaviour need evidence

Process

Step 1: Define What You're Testing

Write 3-5 task scenarios that map to the core jobs in the brief. Each task:

  • Starts with a realistic trigger — "You just bought a new plant and want to add it to the app"
  • Has a clear success condition — "The plant appears in your list with a watering schedule"
  • Does not tell the user how — never say "tap the + button"
Step 2: Select Participants

Recruit 5-8 participants. At minimum include:

  • 1 person who uses a screen reader
  • 1 person over 60
  • 1 person who is not a native speaker of the interface language
  • 1 person with low tech confidence

Reference inclusive-personas for the ability spectrum.

Step 3: Choose Method
MethodWhen to useMinimum participants
Moderated think-aloudNew flows, complex interactions5
Unmoderated remoteSimple tasks, large sample8-12
Guerrilla (hallway)POC validation, time-constrained3-5
Accessibility audit with AT usersAfter build, before ship2-3
Show full SKILL.md (151 more words)Show less
Step 4: Write the Test Script
  1. Welcome — explain what you're testing (the design, not them)
  2. Background — 2-3 questions about their relationship to the problem
  3. Tasks — present each scenario one at a time, observe silently
  4. Debrief — "What was hardest?" "What would you change?"

Never help during a task. Silence is data.

Step 5: Analyse Findings

Classify outcomes per task:

  • Completed easily — no hesitation, no errors
  • Completed with difficulty — hesitation or errors but recovered
  • Failed — could not complete
  • Completed wrong — thought they succeeded but didn't

Severity: Critical (blocks 2+ participants), Major (significant difficulty), Minor (noticed but not impeding).

Step 6: Turn Findings Into Actions

Every finding becomes a design action: "[Severity] [What happened] → [Design action] → [Which agent handles it]"

What You Deliver

  • Task success rates table
  • Ranked findings by severity
  • Design actions with agent assignments
  • Recommendation: iterate / ship / rethink

Integration

  • Informed by: inclusive-personas, design-discovery
  • Feeds into: design-lead, design-builder, design-strategist

When should I use Usability Testing?

Usability Testing fits situations like: conducting usability tests — writing test scripts; selecting participants; analysing findings; turning observations into design actions.

How do I install Usability Testing in Claude Code?

Run `npx skills add Owl-Listener/designpowers --skill usability-testing -a claude-code`. Or copy the skill folder (skills/usability-testing in Owl-Listener/designpowers) into .claude/skills/usability-testing in your project. Claude Code loads it when a task matches its description.

Can I use Usability Testing in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Owl-Listener/designpowers --skill usability-testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/usability-testing, .gemini/skills/usability-testing, .github/skills/usability-testing and .opencode/skills/usability-testing in your project.

What does Usability Testing need to run?

SKILL.md names no scripts, command-line tools or credentials: Usability Testing is instructions for the agent only.

Does Usability Testing access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Usability Testing safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Usability Testing use?

Usability Testing is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Usability Testing use?

About 710 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
