goldseam

Launch an adversarial mutation-testing agent (Opus) that injects targeted regressions into goldseam's production code, runs the suites, and reports which mutations SURVIVED — surviving mutations are direct evidence of test-coverage gaps. Use when the user says "trickster", "mutation test", "break the code", "grade the tests", or after adding production code whose coverage is unproven.

Launch an adversarial bug-hunting code reviewer (Opus) to find real bugs, correctness issues, and trust hazards in the goldseam plugin/engine — not style nits. Use when the user asks for a "red team", "bug hunt", "adversarial review", or at checkpoints after a milestone lands.

Launch an adversarial reviewer (Opus) to find bugs IN THE TEST SUITE — tautological assertions, stub lies, jsdom-shim divergence, vacuous system checks, coverage gaps. Use when the user says "red team the tests", "audit the tests", "are our tests any good", or after adding a large batch of tests.
