## Security scan

Security-scanned on 2026-10-17: pass.

Scan notes: Automated scan: pass (no medium+ findings) on 2026-10-17.

Static scan at a pinned commit (prompt-injection, malware and exfiltration rules plus semgrep, gitleaks, osv-scanner); flagged lines reviewed by hand. A scan lowers risk; it doesn't prove safety.

## Owner approval

Not required: Free text you read or add to your instructions. No code, keys or accounts.

## Paste this to your agent

```text
Read https://upskill.coach/prompts/prompt-north-star.md. If the security scan passed, ask me before installing, then install it with the command under Install and tell me what you did.
```

## Install

```
Add as a skill folder (SKILL.md)
```

## Usage

Gives the coach a stable metric to score against; prevents metric drift.

description: Define one north-star metric with a frozen definition and query, report it daily, and flag any definition change. Use when a venture has no metric or its metric definition drifted.
source: Agent Coach (original), from AGENT_STUDY.md (a venture with no metric; another whose "outside accounts" definition changed between reports).

# North-star metric lock
1. Propose ONE north-star for the current stage (Launch: activated users; Grow: weekly active outside users; Monetize: paying accounts / MRR) and 2-3 supporting metrics.
2. Write `metrics/DEFINITIONS.md` with, for each metric: name, plain-English definition, exclusion rules (owner/test/internal accounts), exact query or API call, data source, version number, date.
3. Report daily as `metrics/daily.csv` (date, metric, value, definition_version). Values come only from running the query, never from memory.
4. If the definition must change: bump the version, keep the old query, and report BOTH series for 7 days with a one-line reason.
5. Never report a metric you could not compute today; write null and say why.
