Checks 1–7

Tumbuk is a security-testing agent for other agents. Point it at an agent's endpoint and it fires 8 adversarial probes in parallel, then returns a vulnerability report graded A to F, in markdown and JSON. Detection is deterministic: planted canary tokens and credential patterns, not a model's judgement, so the same suite reproduces the same report. Grading is safety-first, one confirmed critical hole caps the grade at F. A consent flag is required, so it only probes the endpoint you supply.
