Glossary
| Term | Meaning |
|---|---|
| Item | Any first-class object in the catalog (operator, connection, payload, config, action, task, folder, report, asset, skill, agent, chat, usecase, table). |
| Catalog | The folder hierarchy that holds all items — the shared context the AI and the team work from. |
| laui | LeastAction Unique Identifier — the id of any catalog item. |
| Operator | Python code defining how a task runs (4 methods: initialize, run, check_completion, finish). |
| Connection | Credentials + resource config + concurrency controls for an external system. |
| Payload | The task-specific input (SQL, JSON, Python, string). |
| Config | Defaults, schedule, retries, SLA, parameters — shared via an N-level hierarchy with locked/overridable values. |
| Action | Reusable Python that runs at a lifecycle hook (pre / running / post / UI). |
| Task | An instance: connection + operator + payload (+ config + actions), run on a schedule or on demand. |
| Workflow | A folder of related tasks. |
| Partition | A dimension of a task's primary key — same name + project + different partition = an independent instance. |
| logical_date | The data period a run computes, injected as {{ds}} / {{logical_date}}. |
| next_run_date | The scheduler trigger time; the cron fires when next_run_date ≤ now. |
| Backfill | Running a task for historical dates by assigning past logical_dates. |
| Catch-up | Automatic replay of missed cron slots after an outage/backfill, one logical date at a time. |
| Skill | A markdown knowledge item the AI reads during generation or in the Report Explorer. |
| Usecase | A bundled pipeline blueprint (payloads + skills) an AI agent can read and implement; the runnable examples live in ai/usecases. |
| Agent | A conversational AI item that backs the chat widget (optional MCP tool-calling). |
| Chat | The AI item that powers the generation wizard (AI > Operator/Action/Payload). |
| MCP | Model Context Protocol — connect Claude Code / any MCP client to the catalog with your own AI subscription. |
| Report Explorer | The business-user UI: ask in plain English, read live reports; skill-driven and permission-scoped. |
| Marketplace | Where you discover, import, and publish operators, actions, payloads, skills, and usecases. |
