http-load-profiler

Run stepped HTTP load tests with ab/wrk, ramping concurrency levels to collect p50/p90/p99 latency, detect performance inflection points, and recommend optimal concurrency. Triggered by requests like 'load test this URL', 'benchmark my API', 'find the max concurrency', or mentions of p99 latency, throughput saturation, or capacity planning.

Quality

Content

87%

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

A concise, highly actionable body with executable commands and a complete parameter/output specification, well-organized with a single verified bundle file. The one weakness is the absence of explicit validation/verification checkpoints for a batch operation that produces real load against a target.

Suggestions

Add a brief preflight/validation step before the run (e.g. check that wrk or ab is on PATH, and confirm the target URL returns 2xx with a single low-concurrency probe) so the workflow has an explicit checkpoint.

Include a short post-run sanity check (e.g. flag if any step recorded zero successful requests or if the first step's RPS is implausibly low) as a feedback loop before interpreting inflection points.

Reinforce the authorization warning as an explicit prerequisite checkpoint rather than a passive note, since stepped load testing generates real traffic against the target.

DimensionReasoningScore

Conciseness

Lean and efficient — a feature list, copy-paste Quick Start, a parameter table, output-format samples, and a terse algorithm spec — with no padding explaining what HTTP, latency, or load testing are. Not the level below because it avoids the unnecessary explanatory prose the 2-anchor warns about.

3 / 3

Actionability

Fully executable, copy-paste-ready commands verified against the real script (e.g. 'python3 scripts/http_benchmark.py https://example.com/api/health -s 5,20,50,100,300 -d 15'), a complete parameter table with defaults, and concrete human/JSON output examples — matching the top anchor.

3 / 3

Workflow Clarity

The stepped concurrency process and the four-rule inflection algorithm are clearly sequenced, but there are no validation/verification checkpoints (e.g. confirm wrk/ab present before running, verify target reachable, sanity-check step results) for a batch operation that generates real outbound traffic. The judging guidelines cap batch operations lacking feedback loops at 2, so this is not a 3; it is above 1 because the sequence itself is explicit.

2 / 3

Progressive Disclosure

Well-organized sections (Features, Quick Start, Parameters, Output Format, Prerequisites, Algorithm, Notes) with a single one-level-deep bundle reference (scripts/http_benchmark.py) confirmed to exist; content is appropriately inline rather than nested. Matches the clear-overview anchor for a single-task skill.

Description

100%

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

A precise, third-person description that states concrete capabilities and provides explicit natural-language triggers covering both what and when. It is concise without fluff and unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Names multiple concrete actions — 'run stepped HTTP load tests', 'ramping concurrency levels', 'collect p50/p90/p99 latency', 'detect performance inflection points', and 'recommend optimal concurrency' — matching the top anchor for listing several specific concrete actions.

3 / 3

Completeness

Explicitly answers 'what' (stepped load testing, percentile collection, inflection detection, concurrency recommendation) and 'when' via the 'Triggered by requests like...' clause with concrete triggers, satisfying both halves at the top anchor.

3 / 3

Trigger Term Quality

Natural trigger phrasings a user would actually say ('load test this URL', 'benchmark my API', 'find the max concurrency') plus domain terms (p99 latency, throughput saturation, capacity planning), giving good coverage of natural terms.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (HTTP load/latency profiling with inflection-point analysis) with distinct triggers that would not naturally fire for unrelated skills, matching the clear-niche anchor.
