Performance Test Gatling

performance-test-gatling (EN)

中文版： See the corresponding Chinese skill.

When to Use

• Need performance outputs that should land in Gatling structure.
• The project already uses Gatling or wants Gatling-ready scenarios.

Workflow

• Read and follow the main prompt listed under Progressive disclosure (coverage, structure, quality bar).
• Add only project context that changes the result: scope, environment, constraints, risks, dependencies, expected deliverable.
• If input is incomplete, return a usable first draft and explicitly mark assumptions and gaps.
• Default to Markdown; switch formats only when the user asks.

Core Constraints

• Prioritize by risk / business impact — do not treat everything equally.
• Separate confirmed facts from current assumptions; with no SLA/traffic, label every number as Assumption and list Open Questions.
• Do not invent endpoints, fields, environments, or root causes the user did not provide; secrets are placeholders / env vars only — never real tokens.
• Keep output executable: concrete scenarios, clear priority, clear next steps.
• Default to only the most critical 1–2 scenario types — do not run baseline/load/stress/spike/soak all by default.

Progressive Disclosure

• Before producing output, read and follow prompts/performance-test-gatling.md (minimum coverage, output structure, quality bar).
• When a ready-made template fits: use matching files under output-templates/.
• When the user wants examples or alignment with existing assets: read relevant examples/.
• For deep framework/troubleshoot/schema notes: read only the relevant file(s) under references/, do not load the whole directory.
• For format conversion or helper checks: prefer existing scripts/ over reinventing.
• For evaluating/regressing this skill: use evals/ with skill-up.

Pre-delivery Checklist

• [ ] Followed the main prompt's output structure
• [ ] Minimum coverage focus: target scenarios, load model, test data or feeder needs, ramp profile, thresholds, environment and monitoring, priority bottlenecks, reporting needs, ... (details in main prompt)
• [ ] Covered the minimum checklist, or explained omissions
• [ ] High-risk items have explicit priority
• [ ] Did not invent details the user did not provide
• [ ] Assumptions and gaps are marked

Common Pitfalls

• Do not pretend completeness when scope/context is missing.
• Do not treat every item as equally important.
• Do not skip assumptions and information gaps.
• Do not dump generic theory unrelated to the current toolchain.
