AI Glossary

Testable conditions that define when a feature or model output is “done” and correct.

Acceptance criteria translate requirements into observable checks—e.g., schema validity, golden answers, safety gates. For AI systems they underpin eval harnesses, regression suites, and human-in-the-loop review, linking specs to measurable quality.

The agent’s live plan: ordered steps, open subtasks, and checkpoints toward a goal.

An agenda is the working memory of execution—a list of next actions, blocked items, and completed steps derived from task decomposition and tool results. Surfacing the agenda in UI and logs makes agent runs inspectable and aligns runtime behavior with PRD and acceptance criteria.

Component or prompt pattern that proposes multi-step plans before tools run.

The planner produces candidate sequences of actions—often conditioned on policies, specs, and retrieved context. Separating planning from execution eases testing: you can evaluate plans against acceptance criteria and budgets before side effects occur.

Packaged capability for an agent: instructions, allowed tools, and I/O schemas for one coherent task.

An agent skill bundles system guidance, tool contracts, examples, and eval hooks so a model can repeatedly perform a defined capability—e.g., ‘file an expense’ or ‘run a compliance check’. Skills are the unit of reuse between specs, runbooks, and orchestration layers like Synapse.
