What it does

North Star Metric is an agent skill from phuryn/pm-skills. Define a North Star Metric and 3-5 supporting input metrics that form a metrics constellation. Classify the business game (Attention, Transaction, Productivity) and validate against 7 criteria for an effective North Star. Use when choosing a North Star Metric, setting up a metrics framework, learning about the North Star Framework, or deciding what to measure.

Its SKILL.md is about 1k 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: PM Skills Marketplace: 100+ agentic skills, commands, and plugins — from discovery to strategy, execution, launch, and growth. The licence is MIT.

When your agent uses it

  • Choosing a North Star Metric
  • Setting up a metrics framework
  • Learning about the North Star Framework
  • Deciding what to measure

Example prompts

  • “/north-star-metric”

Workflow steps

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

  1. Easy to Understand: Clear definition that everyone in the organization comprehends
  2. Customer-Centric: Reflects value delivered to customers, not just revenue or activity
  3. Sustainable Value: Indicates habits and long-term customer engagement
  4. Vision Alignment: Represents meaningful progress toward the company's vision and mission
  5. Quantitative: Measurable with clear, numeric tracking
  6. Actionable: Teams can directly influence it through product, marketing, and operational changes
  7. Leading Indicator: Predicts future business success and revenue growth

What it can do on your machine

Read from SKILL.md and the folder at commit 6058e29. 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

    Links to these hosts (documentation or services it may open):

    • productcompass.pm
    • learn.productcompass.pm

    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

North Star Metric loads about 1k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 486 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

North Star Metric

Identify a North Star Metric and 3-5 Input Metrics that form a metrics constellation. Classifies the business game being played and validates against criteria for an effective North Star. Use when defining key metrics, setting up a metrics framework, or choosing what to measure.

Domain Context

NSM is NOT: multiple metrics, a revenue/LTV metric (must be customer-centric), an OKR (that's a goal-setting technique), or a strategy (but choosing the right NSM is a strategic choice).

NSM IS: a single, customer-centric KPI that reflects the value customers get from the product and serves as a leading indicator of long-term business success. You can use Key Results (OKRs) to express expected change in NSM.

When to Use

  • Defining your company's key metric framework
  • Setting up a metrics tracking system
  • Choosing what to measure and optimize for
  • Evaluating potential North Star candidates
  • Triggers: North Star metric, north star, key metric, what to measure, metrics framework, OMTM

The Three Business Games

Before identifying your North Star, classify your business into one of these three games:

  • Attention Game: How much time do customers spend using your product? (Examples: Facebook, Spotify, YouTube, TikTok)
  • Transaction Game: How many transactions occur between customers and your platform? (Examples: Amazon, Uber, Airbnb, PayPal)
  • Productivity Game: How efficiently can someone complete their work or achieve their goals? (Examples: Canva, Dropbox, Loom, Notion)

Prompt

You are a metrics strategist specializing in North Star metrics and growth measurement frameworks.

Given the following business context: $ARGUMENTS

Step 1: Classify the Business Game Determine which game this company plays: Attention, Transaction, or Productivity.

Step 2: Identify the North Star Metric Suggest a single metric that meets all seven criteria for an effective North Star:

  1. Easy to Understand: Clear definition that everyone in the organization comprehends
  2. Customer-Centric: Reflects value delivered to customers, not just revenue or activity
  3. Sustainable Value: Indicates habits and long-term customer engagement
  4. Vision Alignment: Represents meaningful progress toward the company's vision and mission
  5. Quantitative: Measurable with clear, numeric tracking
  6. Actionable: Teams can directly influence it through product, marketing, and operational changes
  7. Leading Indicator: Predicts future business success and revenue growth

Step 3: Identify Input Metrics Define 3-5 Input Metrics (also called leading indicators) that most directly influence and drive the North Star Metric. Each input metric should:

  • Be easier to move in the short term
  • Directly contribute to the North Star outcome
  • Help identify where optimization efforts should focus

Tips for Best Results

  • Provide details about your business model and revenue model
  • Share your company's vision, mission, or long-term goals
  • Include current metrics you're tracking
  • Mention key customer segments and use cases
  • Describe the primary value you deliver to customers
