At most two skills per maintainer, so the board stays varied. The full ranking is in the directory.
Find a skill by
stage of the work.
From the first question about a feature to the rollback plan on launch day.
- Plan & designShape the work before the code: interviews, specs, domain language, plans, API contracts and decision records.12
- BuildWrite the change well: test-first loops, thin verifiable slices and simpler code.13
- Test & debugFind the real cause, prove the fix with evidence, and test in a real browser.12
- ReviewReview changes against your standards and the original intent, and take feedback with rigour.10
- SecurityThreat models, hardening and the checks that matter before real users arrive.16
- PerformanceMeasure first, then fix what the trace actually shows.8
- Ship & operateGit hygiene, guardrails, CI and launch readiness.15
- Cloud & infrastructureProvision, secure and run infrastructure: AWS, Azure, Google Cloud, Cloudflare, Terraform, containers and Kubernetes.20
- Databases & dataSchemas, queries, migrations and access rules for the databases you actually run.15
- Languages & frameworksCurrent, idiomatic practice for a specific language or framework, from the people who maintain it.24
- Agent workflowContext, delegation, and building your own skills and tools.10
