Survey any codebase as a senior advisor and produce prioritized, self-contained implementation plans for OTHER models/agents to execute. Strictly read-only on source code — never implements, fixes, or refactors anything itself. Use when asked to audit a codebase, find improvement opportunities (bugs, security, performance, test coverage, tech debt, migrations, DX), suggest features or where to take the project next (roadmap, product direction), or generate handoff plans for another agent to implement.

Run Ginkgo suites in parallel — ginkgo -p / --procs, the separate-process (not goroutine) model, SynchronizedBeforeSuite/SynchronizedAfterSuite vs BeforeSuite, GinkgoParallelProcess() for sharding ports/tmpdirs/databases, building a binary once via gexec, piping child-process output to GinkgoWriter, and what N processes actually cost (compilation vs teardown, and the fixed ~1s --race adds per suite — GORACE=atexit_sleep_ms=0). Use when parallelizing a suite, speeding up integration tests, auditing why a parallel run is slow, fixing parallel-only flakes/races, sharding external resources, or choosing between BeforeSuite and SynchronizedBeforeSuite.
