Change how a Harness FME feature flag serves traffic in environments. Covers percentage rollout, individual targets, targeting rules (attribute/segment/flag-dependency), defaultTreatment, trafficAllocation, treatments, kill/restore, and copying or initializing a definition in an environment. Use when asked to ramp a flag, add rules/users, change allocation, kill/restore, or promote config. Not for creating flags (create-feature-flag), metadata like tags/owners/archive (manage-flag-lifecycle)…
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
# Update Flag Targeting
Change how an existing Harness FME feature flag serves traffic in one or more environments. **Always read the current definition first**, then merge-patch only what changes. Show a diff of just what changed and use plain-language before/after to describe who gets what.
Related: Segment membership changes are `/manage-segments`; deep flag analysis (impact, dependencies, single-flag state) is `/explain-flag`. Reverse-lookup scans (dependents, segment usage) are in [tool-map.md](../../../references/fme/tool-map.md#reverse-lookup-scans).
## 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 environments | `harness_list` · `fme_environment` · `compact: false` | `harness list fme_environment --json` |
| List flag definitions | `harness_list` · `fme_feature_flag_definition` · `params: { feature_flag_name }` · `filters: { offset: 0, limit: 100 }` · `compact: false` | `harness list feature_flag:definition <flag> --json` |

How to install
mdr add harness/harness-skills/update-flag-targeting@sha256:6811f5d79e09acb0The line at the top of this page pins the label v1.2.2, 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.
