Prefer defaulting and naked switches over if/else chains for shallow branching logic in Go. Use when writing or refactoring conditional logic with 1-3 branches.

Use when adding a cross-cutting concern (OTEL tracing, logging, metrics, caching, auth) to a business domain, creating files under business/domain/*/extensions/*, or adding the extension seam (ExtBusiness/Extension) to a *bus package.

Enforce primitive-at-edges / strong-types-in-Business layering and the toBus/fromBusResponse/toDB converter pattern. Use when writing, editing, or auditing Go files under app/*, business/domain/*, or .../stores/*db.

Service Diffguard: read-only PR review lenses for correctness, error visibility, comment truthfulness, test coverage, type/contract boundaries, and simplification across every language in this repo (Go, Vue/JS/SCSS, Rego, protobuf, SQL, Helm/YAML, shell). Use…

Apply modern Go syntax guidelines based on the project's Go version. Use whenever writing, editing, or reviewing Go (.go) code — not only when explicitly asked for guidelines.

Using the Kronk MCP service in the default agent configuration, where Kronk is wired directly into the host (OpenCode, Kilo, Pi) as an MCP server. Exposes `fuzzy_edit` (fallback for the host's exact-match edit when whitespace / line-endings cause it to miss)…
