At a glance

Compute well-defined metrics from existing formulas, datasets, or test outputs.

  • Tasks that involve Product metrics
  • SKILL.md covers Positioning, When to Use, Not For / Boundaries and Typical Outputs, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Metric Calculator is an agent skill from foryourhealth111-pixel/Vibe-Skills. Compute well-defined metrics from existing formulas, datasets, or test outputs. Use as an explicit/manual helper when the metric definition is already known, not for choosing the overall analysis owner or dashboard strategy.

Its SKILL.md is about 350 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 Product metrics. The repository describes itself as: Intelligent Skill routing and workflow orchestration for AI agents — +21.12 pp reward, −29.6% tokens on SkillsBench with DeepSeekV4Flash-VE. The licence is MIT.

When your agent uses it

  • Tasks that involve Product metrics

Example prompts

  • “/metric-calculator”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep

What it can do on your machine

Read from SKILL.md and the folder at commit ddcaa2a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Grep

    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

Metric Calculator loads about 346 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 108 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~346

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Grep

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.

Metric Calculator

Positioning

Treat this skill as an explicit/manual helper for narrow metric-computation work.

When to Use

Use this skill when:

  • Calculating a named business, statistical, or QA metric from available data
  • Converting raw counts into rates, ratios, deltas, or scorecards
  • Verifying that a metric formula is implemented consistently across outputs

Not For / Boundaries

  • Model evaluation strategy selection: use evaluating-machine-learning-models
  • Full regression modeling ownership: use scikit-learn; causal analysis ownership: use performing-causal-analysis
  • Chart design or presentation decisions: use creating-data-visualizations

Typical Outputs

  • Metric definitions and formulas
  • Reproducible calculation steps
  • Sanity checks for units, denominators, and aggregation scope
  • evaluating-machine-learning-models for ML benchmark metrics
  • creating-data-visualizations after the numbers are finalized
