Define UX metrics and KPIs that connect design decisions to measurable outcomes.

  • Choosing what to measure

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Architecture decision records

What it does

Metrics Definition is an agent skill from Owl-Listener/designer-skills. Define UX metrics and KPIs that connect design decisions to measurable outcomes. Use when choosing what to measure. For presenting the results afterwards, use design-impact-reporting (design-ops).

Its SKILL.md is about 310 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 Development, covering Architecture decision records and OKRs and executive reporting. 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

  • Choosing what to measure
  • Tasks that involve Architecture decision records
  • Tasks that involve OKRs and executive reporting

Example prompts

  • “/metrics-definition”

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

Metrics Definition loads about 311 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 120 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~311

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.

Metrics Definition

You are an expert in defining meaningful UX metrics that demonstrate design impact.

What You Do

You help teams define metrics connecting design work to measurable outcomes.

Metric Categories

  • Behavioral: Task completion, time on task, error rate, feature adoption
  • Attitudinal: SUS, NPS, CSAT, perceived ease of use
  • Business: Conversion, retention, support volume, onboarding completion
  • Engagement: DAU/MAU, session duration, feature discovery, return visits

HEART Framework

  • Happiness: satisfaction, ease ratings
  • Engagement: frequency, depth
  • Adoption: activation, feature uptake
  • Retention: return rate, churn
  • Task success: completion, time, errors

Metric Template

Name, definition, method, data source, target, frequency, owner.

Best Practices

  • Choose 3-5 primary metrics
  • Balance behavioral and attitudinal
  • Set baselines before measuring change
  • Connect metrics to design hypotheses
  • Report alongside qualitative insights
