Specify tool-neutral API load, stress, and recovery testing with parameterized workload models, SLO percentiles, and finite overload bounds. Use when evaluating API latency, throughput, saturation, or recovery behavior under concurrent traffic.
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 Performance, Load, and Recovery Testing ## **Priority: P1 (HIGH)** ## Workflow 1. **Parameterize Workload**: Source arrival rate vs concurrency, request mix, duration, and SLO percentiles from approved requirements/SLOs. Missing approvals block execution, not offline planning. 2. **Preflight & Bound (C4)**: Verify explicit target authorization and synthetic isolation. Enforce distinct finite ceilings, each with its own unit — `maxArrivalRateRps`, `maxInFlightRequests`/`maxConcurrency`, `maxPayloadBytes`, duration — plus cancellation hooks and continuous stop tripwires. A rate ceiling is not a concurrency bound. 3. **Establish Phase-Specific Baseline**: Exclude warmup. Measure baseline throughput, success latency, error latency ($p50, p95, p99$), and baseline error budget. 4. **Evaluate Overload & Degradation**: Apply stepped ramp up to authorized stress cap. Distinguish expected shedding (e.g. 429/503) from unexpected system faults; abort if tripwires fire. …

How to install
mdr add hoangnguyen0403/agent-skills-standard/quality-engineering-api-performance-testing@sha256:c7d76ae4db87ee8cThe line at the top of this page pins the label git:20261027.7209c6c, 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.
