Sumaiya Shrabony describes a 19-skill content systemAn AI agent skill is a reusable package of instructions, resources, and tool guidance for performing a bounded kind of work. whose seven handoffsAgent orchestration coordinates AI agents, tools, people, tasks, state, and control flow so a larger workflow reaches a verified outcome. revealed a recurring problem: agent output can look complete while carrying a hidden error into every downstream step. Prompt improvements alone do not create reliable boundaries.
She maps five software-delivery controls onto agent workflows: explicit contracts, automated testsDeterministic software verification checks an output with a repeatable procedure that produces the same result for the same inputs and state., blocking gatesA guardrail is a technical or procedural control that limits unsafe, disallowed, deceptive, or otherwise unwanted AI behavior., versioned artifacts and audit trailsAn agent audit trail is an ordered, durable record of an AI agent's instructions, decisions, tool calls, state changes, identities, and outcomes.. Each control makes a handoff observable and gives the pipeline a defensible way to reject malformed or unsupported work.
Shrabony recommends starting with the most expensive failure point, such as a public false claim or a schema error that cascades across several skills. A warning-only check is not a gate; the system must block the artifact from moving forward.
