api-load-tester SKILL.md skillA
api-load-tester from onewave-ai/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add onewave-ai/claude-skills/api-load-tester@git:20260608.d82d20fPins git:20260608.d82d20f in mdr.lock. Pin the fingerprint instead.

Load tests API endpoints with progressive concurrency. Measures response times, error rates, throughput, and identifies breaking points. Generates a detailed report with latency percentiles, throughput curves, bottleneck analysis, and optimization recommendations.
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
# API Load Tester Stress-test HTTP endpoints under increasing load, identify breaking points, and produce a report with actionable recommendations. ## Contents - `references/tool-commands.md` -- tool invocations (hey/wrk/ab/curl), default concurrency stages, per-stage data to capture. - `references/metrics-interpretation.md` -- latency, throughput, error, breaking-point, and bottleneck classification. - `references/output-template.md` -- exact structure for `api-load-report.md`, including ASCII charts and scaling table. - `references/rules-and-examples.md` -- safety rules, error handling, and example invocations. ## Inputs Collect from the user. Ask before proceeding if a required input is missing. **Required**: endpoint URL(s) (with method, headers, body as needed); expected latency thresholds. Default thresholds if unspecified: p50 < 100ms, p95 < 300ms, p99 < 1000ms. **Optional**: concurrent users or range (default ramp 1 to 100); authentication; request payloads; custom headers; test duration (default 10s per stage); ramp pattern (default step ramp, doubling each stage); success criteria (default 2xx); known rate limits; environment label (prod/staging/dev). ## Workflow …

How to install
mdr add onewave-ai/claude-skills/api-load-tester@sha256:58529056586bf8e6The line at the top of this page pins the label git:20260608.d82d20f, 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.
