create-metric from harness/harness-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add harness/harness-skills/create-metric@v1.4.2Pins v1.4.2 in mdr.lock. Pin the fingerprint instead.

Create a Harness FME metric: helps decide what to measure, suggests candidate metrics from application code, resolves traffic type and event type IDs, drafts the payload, then creates. Use when asked to create or define a new metric, decide what to measure, or get metric suggestions from application code. Doesn't attach metrics to experiments (manage-experiments) or add the tracking call (instrument-metric). Trigger phrases: create/define a metric, new metric, what metrics should we create…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. 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.
What the file says
# Create Metric
Create an FME metric definition, with guidance on what makes a good metric and what to measure. Resolves traffic types and events against real data and asks the user to select an owner instead of guessing IDs. Owner existence is validated by the API on creation/readback; the declared tools do not provide an owner-directory lookup. Design guidance lives in [metric-design.md](../../../references/fme/metric-design.md). Related: `/manage-experiments` attaches metrics; `/instrument-metric` adds tracking calls.
For every phase marked **Stop condition**, see [stop-conditions.md](references/stop-conditions.md) before improvising.
## Tools
Works through the Harness MCP server or the Harness CLI; names are from [tool-map.md](../../../references/fme/tool-map.md).
| Operation | MCP | CLI |
|-----------|-----|-----|
| List metrics | `harness_list` · `fme_metric` · `filters: { name?, traffic_type_id?, limit }` · `compact: false` | `harness list metric --name <substring> --traffic-type-id <id> --json` |
| List traffic types | `harness_list` · `fme_traffic_type` · `compact: false` | `harness list traffic_type --json` |

How to install
mdr add harness/harness-skills/create-metric@sha256:d8aa79f139e6a59cThe line at the top of this page pins the label v1.4.2, 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.
