Create, update (metrics, dates, description, hypothesis, baseline/comparison treatments, status), or delete Harness FME feature-flag experiments. Delegates metric selection to choose-metric, metric creation to create-metric, event wiring to instrument-metric, results to review-experiment-results, flag/definition prep to create-feature-flag and update-flag-targeting. Use when asked to create, modify, pause, resume, complete, or delete an experiment. Do not use for explaining results…
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
# Manage Experiments
Create, update, or delete FEATURE_FLAG experiments. AI_CONFIG mutation workflows are not implemented here; use read-only results inspection or a separately supported workflow. Orchestrates decisions and delegates
metric selection, flag setup, and results interpretation to specialist skills.

## 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 experiments** | `harness_list` · `fme_experiment` · `filters: { parent_type, parent_name?, environment_id?, status?: ["ACTIVE", "PAUSED"], … }` · `compact: false` | `harness list experiment --parent-type FEATURE_FLAG [--search <name>] [--status ACTIVE]`, then again with `--status PAUSED` |

How to install
mdr add harness/harness-skills/manage-experiments@sha256:a2df2e3d52c544fbThe line at the top of this page pins the label v2.1.0, 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.
