How Go tests are written in these repos: assertions, tables, test doubles, helpers, async waits, golden files, fuzzing, benchmarks, and integration tests against a real Postgres via the bundled pgtest helper (one shared testcontainer, a fresh database per test). TRIGGER — load BEFORE writing, editing, or reviewing any *_test.go file, testdata/ golden file, fuzz target, or benchmark, or when the task mentions go test, test helper, fake, mock, stub, table test, testcontainers, TestMain, test database, flaky test, or coverage in a Go repo. Plain requests count: “write the tests,” “add a test for this,” “fix the failing test,” or a feature task whose last step is testing it. Load alongside go-idiomatic and tdd, not instead of them. SKIP when no Go test code is written or judged

SCOPE HARD RULE: requires two code versions (A and B). A single version for bug-finding uses logic-review; one version + a failing test uses logic-locate; explaining what one piece of code does uses logic-explain; codebase audit uses logic-health. Do NOT trigger for: single-version review, performance comparison, design-quality comparison, or "which is better-written" questions.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
