Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The SKILL.md body is concise, specific, and well-sequenced, with good examples and a useful error-recovery table. The bundle is the weak point: two of the three referenced files hold off-topic content from what appears to be an API-development skill rather than the load-testing guide and error patterns the body promises.

Suggestions

Rewrite references/implementation.md as an actual load-testing implementation guide (script authoring conventions, monitoring correlation, report generation) — the current file covers API architecture design and endpoint implementation, which is unrelated to this skill.

Rewrite references/errors.md to extend the body's load-test error table with comprehensive load-testing error patterns — the current file covers API runtime errors (schema validation, token lifecycle, consumer rate limiting) rather than test-execution failures.

Add a minimal inline runnable snippet or command (e.g., a one-line k6 run invocation) to the body so the core loop can start without opening references/examples.md first.

DimensionReasoningScore

Conciseness

The body is lean and dense with specifics (stage durations, threshold values, traffic percentages) and explains nothing Claude already knows; every section earns its place.

5 / 5

Actionability

Concrete parameterized guidance ("ramp-up (2 min), sustained load (10 min), spike (2 min at 3x)", "p95 response time < 500ms, error rate < 1%") is mostly executable, but the body contains no inline code or commands — all runnable scripts live in references/examples.md.

4 / 5

Workflow Clarity

A clear 9-step sequence with threshold assertions as pass/fail checkpoints and an error-cause-solution recovery table. Not 5 because there is no explicit validate-before-scaling loop (e.g., re-verify thresholds before the 2x/5x/10x stages) or re-run-on-failure step.

4 / 5

Progressive Disclosure

The body defers to three well-signaled, one-level-deep references that all exist, but two deferrals are broken promises: references/implementation.md ("full implementation guide") covers designing and building an API, and references/errors.md covers API runtime errors like schema validation and auth tokens — neither contains the load-testing material the body points to, so content is not appropriately split across the bundle.

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is well-structured with an explicit what, an explicit use-when clause, and concrete trigger phrases. Its main weakness is a thin action list that undersells the skill's actual capabilities.

DimensionReasoningScore

Specificity

"Execute comprehensive load and stress testing to validate API performance and scalability" names the domain with 1-2 concrete actions (load testing, stress testing), but omits script generation, tooling (k6/Artillery), and reporting, so it is not comprehensive.

3 / 5

Completeness

Explicitly answers both what ("Execute comprehensive load and stress testing to validate API performance and scalability") and when ("Use when validating API performance under load") with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Natural trigger phrases "load test the API", "stress test API", and "benchmark API performance" are exactly what users would say, though common variations like "soak test", "throughput", "spike test", and "scalability test" are missing.

4 / 5

Distinctiveness Conflict Risk

Load/stress testing APIs is a distinct niche with targeted triggers, but "benchmark API performance" and "validate API performance" create minor overlap risk with general benchmarking or API monitoring skills.
