What it does

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.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add phuryn/pm-skills --skill north-star-metric

cp -r pm-skills/pm-marketing-growth/skills/north-star-metric ~/.claude/skills/north-star-metric

Safety box score

Grade A, minimal risk: 4 of 100 risk points, rated 2026-10-20. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This is a markdown-only prompt skill for defining a North Star Metric and related input metrics. It does not ship executable code or touch local files, but it does include optional links to external Product Compass resources that an agent may browse if asked.

Category levels, from 0 (none) to 3 (high)
Category	Level	Why
Code & shell execution	0 (none)	`SKILL.md` contains only prose and prompts; there are no shell commands, scripts, or code blocks to run.
Network access	1 (low)	The file includes outbound links to external resources (`https://learn.productcompass.pm/nsm101`, `https://www.productcompass.pm/...`), but nothing auto-fetches them or sends local data.
Filesystem reach	0 (none)	No paths, read/write instructions, or references to modifying files outside the skill text itself.
Secrets & credentials	0 (none)	The skill does not ask for tokens, passwords, `.env` files, browser sessions, or other credentials.
Privilege & persistence	0 (none)	There is no request for sudo, global installs, services, scheduled tasks, or OS/shell configuration changes.
Instruction hijack surface	0 (none)	The prompt text sets a role for the assistant, but it does not instruct it to ignore higher-priority rules, hide behavior, or follow remote instructions.
Irreversible actions	0 (none)	It is advisory only; it suggests metrics and classifications but does not send messages, deploy, publish, pay, or delete anything.
Transparency	0 (none)	All content is plain, human-readable markdown; there are no binaries, minified blobs, or decoded-at-runtime payloads.

Before installing

Confirm the repo only ships `SKILL.md` and no scripts or installers.
Decide whether you want the agent to browse the linked Product Compass pages.
