Conciseness

The body is dense and assumes competence — exact MCP operations with parameters, regex constraints, naming traps, pagination quirks — with no filler explaining what feature flags or pipelines are. However, the killed-flag readback/approval procedure is restated nearly verbatim in Phases 4, 5, 6, and Troubleshooting, and the L2 'stops short of archiving' caveat repeats four times, which goes slightly beyond 'minor instances' of over-explanation.

Actionability

Guidance is fully executable: the Tools table gives exact MCP operation/argument triples and literal CLI commands ('harness list feature_flag:definition <name> --json'), Phase 7 gives concrete YAML rules (stage/step identifier regexes, 'pipeline: root', quoted boolean-like treatment names, exact step-name traps like 'FmeFlagSetIndividualTargets not FmeFlagSetTargets'), and Troubleshooting entries end in specific fixes. YAML details are delegated to real catalog/blueprint files rather than pseudocode.

Workflow Clarity

Nine explicitly sequenced phases with validation checkpoints throughout: 'Confirm before write', Phase 6 'Do not proceed until user confirms', Phase 8's feedback loop ('On validation errors, read message, fix, retry'), and 'Get pipeline before merging; show diff' for updates. The destructive-write cap is satisfied and exceeded — approval checkpoints, diff review, and error-recovery loops are all explicit.

Progressive Disclosure

The body is a genuine overview that clearly signals one-level-deep local references — scenarios.md, blueprints.md, building-blocks.md, step-catalog.md — all of which exist in the bundle, with blueprints.md linking onward to eight real per-scenario YAML files. Minor gaps keep it below 5: several references point outside the bundle via deep relative paths (../../../references/fme/tool-map.md, write-safety.md, scope-establishment.md, templates/operation-summary.md), and some detailed procedural material (the full killed-flag readback procedure, HarnessApproval schema fields) is inlined in SKILL.md rather than split into a reference.

Specificity

The description enumerates concrete capabilities — 'Generate Harness pipelines with FeatureFlag or Custom stages', 'Composes FmeFlag* steps with optional HarnessApproval/Wait/Jira/ServiceNow/metric gates' — and lists eight specific rollout scenarios (progressive ramp, multi-env promotion, beta cohorts, config promotion, bootstrap, retirement, segment sync, test targeting). Coverage is comprehensive with named step types and gate mechanisms, matching the top anchor rather than the 'several specific actions; minor gaps' anchor at 4.

Completeness

Both questions are answered explicitly: what ('Generate Harness pipelines... for flag rollout scenarios' with the full scenario list) and when ('Use when asked to build a flag rollout pipeline, promote flags across environments, or automate flag lifecycle', plus a literal 'Trigger phrases:' list). It also adds explicit exclusions ('Do not use for direct flag operations... or general CI/CD'), which exceeds the score-4 anchor where 'when' is only adequately explicit.

Trigger Term Quality

Explicit trigger phrases — 'FME pipeline, feature flag pipeline, flag rollout pipeline, progressive rollout, multi-environment promotion, flag bootstrap' — plus 'Use when asked to build a flag rollout pipeline, promote flags across environments' give good natural-keyword coverage with synonyms. A few plausible user phrasings (e.g., 'gradual rollout', 'ramp up a flag', 'kill a flag') are absent, so it sits between the 'good coverage' (4) and 'comprehensive coverage' (5) anchors, closer to 4.

Distinctiveness Conflict Risk

The niche is clear (FME flag rollout pipeline generation) and conflict risk is actively reduced by explicit boundaries: 'Do not use for direct flag operations (update-flag-targeting) or general CI/CD (create-pipeline)' and 'Related: create-trigger (automate), run-pipeline (execute)'. This matches the 'clear niche with distinct triggers; minimal conflict risk' anchor.
