Ensure every success metric is paired with guardrail metrics and check for trade-offs before presenting improvements as wins. Guardrails protect against winning the metric game while losing the business game. Apply this skill whenever you define a metric, create a metric spec, document a KPI, report positive findings, present an improvement, analyze metric changes, investigate metric lifts, share good news about metrics, celebrate wins, or present results showing any metric increased.

The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Skill: Guardrails Awareness
## Purpose
Ensure that every success metric is paired with at least one guardrail metric, and that positive findings are checked for trade-offs before being presented as wins.
## When to Use
Apply this skill in two situations:
1. **When defining metrics** — after using the Metric Spec skill, check whether the metric has a guardrail pair
2. **When reporting positive findings** — before presenting any improvement, check whether a related guardrail metric degraded
## Instructions
### What Are Guardrails?
A **guardrail metric** is a metric you don't want to degrade while optimizing a success metric. Guardrails protect against winning the metric game while losing the business game.
```
SUCCESS METRIC: The metric you're trying to improve
GUARDRAIL: The metric that must not get worse
```
**The rule:** Never celebrate an improvement on a success metric without checking its guardrail(s). An improvement with a degraded guardrail is a trade-off, not a win.
### Common Guardrail Pairs
| Success Metric | Guardrail(s) | Why |
|---------------|-------------|-----|

The line at the top of this page pins the label git:20260827.7ff2e25, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
