What problem does it solve? Teams often lack performance regression checks tied to their actual critical user flows, making slowdowns invisible until users complain. This Skill guides the discovery of core flows and produces a concrete benchmark proposal with explicit thresholds before any script is written. ## Core Features & Use Cases - Critical Path Discovery: Identifies core user or system flows from docs, routes, commands, or tests, plus any existing benchmark, load test, Lighthouse, or timing scripts. - Threshold Definition: Requires explicit pass/fail thresholds and records environment assumptions for repeatable local checks. - Approval-Gated Output: Produces a structured Benchmark Proposal (critical path, metric, threshold, command, data setup) and never writes benchmark scripts without approval. - Use Case: Before optimizing an API endpoint, use this Skill to propose a benchmark script targeting the checkout flow with a 500ms p95 threshold, then get approval before generating scripts/benchmark.ps1 or scripts/benchmark.sh. ## Quick Start Ask the agent to propose a benchmark for the most critical user flow in this project with explicit pass/fail thresholds.
