Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification

Use when adding minimal CI automation for lint, tests, and type checks in Python research code.

Define canonical dotnet format and analyzer verification commands, and provide scripts that generate a format/analyzer report. Use when checking formatting or Roslyn analyzers without reformatting everything.

Triage a production incident with safe, minimal changes and rollback guidance.

Convex database patterns and best practices for RFP Discovery. Use when writing Convex queries, mutations, actions, or schema definitions. Also helpful for real-time subscriptions and auth integration.
