Conciseness

Assumes competence — no explanation of what gRPC or CI is — but has trimmable redundancy: the flag table quotes ghz docs verbatim ("Number of requests to run. Default is 200") and overlaps the config JSON example, and prose restates commands ("Run for 60s, 50 concurrent workers, capped at 200 RPS"). Not 5 for those instances; not 3 since the bulk is efficient.

Actionability

Fully executable throughout: install commands, a complete config JSON, runnable ghz invocations, a full GitHub Actions workflow, and a copy-paste-ready compare-ghz.py covering the common CI gating case. Matches the anchor for complete, specific examples.

Workflow Clarity

Clear sequenced sections (install → verify → configure → run → parse → gate) with checkpoints such as `ghz --version`, warmup via `skipFirst`, and a compare gate that exits 1 on regression. Not 5: no error-recovery guidance when the gate fails (only exit), and the flow is section-based rather than an explicit validate→fix→retry loop.

Progressive Disclosure

Well-organized single file with clear sections; all references are external URLs or clearly labeled one-level sibling skills, with no nested reference chains. Not 5: the full CI workflow YAML and compare-ghz.py are exactly the content that would normally live in bundle scripts/ or references/ files, keeping SKILL.md leaner.

Specificity

Lists multiple concrete capabilities — "ghz runs with request count, concurrency, rate and duration", "JSON, CSV or HTML output", "p50, p95 and p99 latency, RPS and error rates checked in CI" — comprehensively covering load parameters, output formats, and metrics. Not 4: coverage has no notable gaps.

Completeness

Explicitly answers both: "Use when a gRPC service needs load testing or a latency regression gate" (when, with concrete trigger phrases) and a specific capability list (what). Not 4: the 'when' clause is explicit and concrete rather than merely present.

Trigger Term Quality

"gRPC service", "load testing", and "latency regression" are phrases users would naturally say, but common synonyms like "benchmark", "stress test", or "throughput" are missing. Not 5 for those gaps; not 3 because the core natural trigger phrases are present.

Distinctiveness Conflict Risk

Clearly scoped to gRPC via "a gRPC service" and the named tool ghz, with CI-gating context — a distinct niche with minimal overlap against generic or HTTP-focused load-testing skills. Not 4: no meaningful conflict risk remains.
