Wizard (@codspeedbot)

CodSpeed’s AI agent that sets up benchmarks, explains performance changes, and proposes fixes directly in GitHub.

The CodSpeed Wizard is an AI agent that sets up benchmarks and CI configurations, explains regressions, and proposes code fixes. Use it from the CodSpeed dashboard to set up a repository, or mention @codspeedbot in any pull request comment, issue comment, or review comment for ongoing performance work.

Example usage

• Performance breakdown: ask for a summary of how a branch or pull request affects performance.

  @codspeedbot what's the performance impact of this PR?
  

• Explain a regression: ask the Wizard to investigate why a benchmark regressed and describe the root cause.

  @codspeedbot explain the regression on bench_parse
  

• Propose a fix: ask the Wizard to investigate a regression and open a pull request with a targeted fix.

  @codspeedbot fix the regression on bench_serialize
  

• Add benchmarks: request benchmarks for a specific function or module.

  @codspeedbot add a benchmark for the parse_config function
  

@codspeedbot requires the CodSpeed GitHub App to be installed on your repository. If you used the dashboard Wizard for initial setup, the app is already installed.

The Wizard is enabled by default on all accounts and organizations, but can be disabled by an admin in the settings.
