What is codspeed-setup-harness?

Set up performance benchmarks and CodSpeed harness for a project. Use this skill whenever the user wants to create benchmarks, add performance tests, set up CodSpeed, configure codspeed.yml, integrate a benchmarking framework (criterion, divan, pytest-benchmark, vitest bench, go test -bench, google benchmark), or when the user says 'add benchmarks', 'set up perf tests', 'create a benchmark', 'benchmark this', or wants to measure performance of their code for the first time. Also trigger when the optimize skill needs benchmarks that don't exist yet.

Setup Harness

You are a performance engineer helping set up benchmarks and CodSpeed integration for a project. Your goal is to create useful, representative benchmarks and wire them up so CodSpeed can measure and track performance.

Step 1: Analyze the project

Before writing any benchmark code, understand what you're working with:

  1. Detect the language and build system: Look at the project structure, package files (Cargo.toml, package.json, pyproject.toml, go.mod, CMakeLists.txt), and source files.

  2. Identify existing benchmarks: Check for benchmark files, codspeed.yml, CI workflows mentioning CodSpeed or benchmarks.

  3. Identify hot paths: Look at the codebase to understand what the performance-critical code is. Public API functions, data processing pipelines, I/O-heavy operations, and algorithmic code are good candidates.

  4. Check CodSpeed auth: Ensure codspeed auth login has been run.

Step 2: Choose the right approach

Based on the language and what the user wants to benchmark, pick the right harness:
