Diagnose and Improve Full-Stack Performance

Full-stack teams often lack a repeatable way to measure performance and locate bottlenecks. This skill provides testing workflows, diagnostic commands, optimization guidance, and report structures.

Testar

Usando "perf-fullstack-engineer". Define a baseline for a checkout API expecting 200 requests per second.

Resultado esperado:

Target 200 requests per second with P95 below 500 milliseconds and errors below 0.1 percent. Measure CPU, memory, database latency, and saturation.

Usando "perf-fullstack-engineer". Diagnose rising P99 latency while CPU remains below 50 percent.

Resultado esperado:

Primary hypotheses: database lock waits, connection pool saturation, external dependency latency, or garbage collection pauses.
Next checks: correlate traces, pool metrics, slow queries, lock activity, dependency timing, and runtime pause data.

Usando "perf-fullstack-engineer". Outline a performance report after an optimization.

Resultado esperado:

Compare the same workload before and after the change. Show latency percentiles, throughput, errors, resource use, remaining bottlenecks, and release recommendations.

The skill is readable Markdown guidance with no executable package, prompt injection, credential collection, obfuscation, or covert data transfer. Static alerts primarily misread Markdown backticks, Chinese text, placeholders, localhost URLs, and documented developer commands as dangerous behavior.

O que você pode criar

Establish a Performance Baseline

Define service targets, select test scenarios, and produce a repeatable baseline before a release.

Diagnose a Slow Application

Correlate latency, resource, runtime, database, and application signals to prioritize likely bottlenecks.

Plan Capacity for Growth

Model peak traffic, identify system limits, and organize scaling recommendations with measurable acceptance criteria.

Teste estes prompts

Define a Baseline

Create a performance baseline for [service]. Use [traffic profile], [latency target], [error target], and [environment]. List assumptions and required metrics.

Design a Load Test

Design a [tool] load test for [workflow]. Include stages, data preparation, checks, thresholds, monitoring, cleanup, and a safe execution sequence.

Analyze a Bottleneck

Analyze these performance results: [results]. Correlate application, host, database, runtime, and network evidence. Rank hypotheses and propose verification steps.

Build a Capacity Plan

Create a capacity plan for [system] at [forecast load]. Estimate limits, identify architecture risks, compare scaling options, and define regression gates.

Boas práticas

Confirm target ownership, isolate the test environment, and obtain approval before generating load.
Warm the system, monitor every layer, increase load gradually, and repeat comparable tests.
Base conclusions on correlated metrics and document assumptions, environment differences, and data limitations.

Evitar

Do not run stress tests against production or third-party systems without explicit authorization.
Do not optimize from averages alone; inspect percentiles, errors, saturation, and resource trends.
Do not change multiple variables between baseline and comparison runs.

Perguntas frequentes

Does this skill run performance tests automatically?

No. It provides workflows, examples, diagnostics, and report structures. Execution requires installed tools, adapted targets, and user authorization.

Which load-testing tools does it cover?

It covers k6, JMeter, Locust, wrk, Vegeta, and Apache Bench, with guidance for selecting tools by scenario.

Can it analyze database performance?

Yes. It covers query plans, slow queries, active sessions, locks, indexing, connection pools, and common MySQL and PostgreSQL diagnostics.

Does it support frontend performance work?

Yes. It covers Lighthouse, browser diagnostics, code splitting, lazy loading, virtual lists, image optimization, caching, and content delivery networks.

Can I use its thresholds without changes?

No. Example thresholds are starting points. Set targets from business requirements, service objectives, historical baselines, and environment constraints.

Is production load testing recommended?

No. Use an isolated representative environment unless your organization has an approved production testing process with safeguards and monitoring.
