# Glossary

Short definitions of the terms you'll see across these docs, with links to the
full explanations.

| Term | Meaning |
| ---- | ------- |
| **Automation** | An autonomous loop bound to a repository and a schedule that spawns implementations without anyone present. See [Automations](/concepts/automations). |
| **Blueprint** | The workflow template a run follows. Task blueprints include *bug fix*, *feature*, and *quick change*. |
| **Brief** | A reviewed specification an agent works from (`draft → approved → archived`). See [Briefs](/concepts/briefs). |
| **Hook** | A command run at a sandbox lifecycle point. The `SandboxReady` hook runs setup after the sandbox is ready. See [Hooks](/configuration/hooks). |
| **Implementation** | One autonomous run that takes a task from plan to pull request. See [Tasks & implementations](/concepts/tasks). |
| **Insights** | Workspace analytics on pull-request activity, Trevize's contribution, and cost. See [Insights](/concepts/insights). |
| **Integration** | A connected external service (GitHub, Linear, Claude Code, MCP, Neon, Sentry, Supabase). See [Integrations](/integrations). |
| **Knowledge** | Durable observations agents capture as they work, searchable by later runs. See [Knowledge & memory](/concepts/knowledge). |
| **MCP** | Model Context Protocol — the Trevize MCP server connects Claude Code to your workspace. See [MCP](/integrations/mcp). |
| **Observation** | A single unit of captured [knowledge](/concepts/knowledge) (decision, bug fix, feature, refactor, discovery, or change). |
| **Preview** | A live, running view of your app served from the sandbox. Configured with [preview targets & processes](/configuration/preview). |
| **Preview process** | One command + port within a preview target (e.g. `web`, `api`). |
| **Preview target** | A named group of processes that together form a previewable app. |
| **Pull request** | The GitHub PR every run produces for you to review and merge. |
| **Resource** | A managed dependency (e.g. a database branch) provisioned per run and mapped into the sandbox. See [Resources](/configuration/resources). |
| **Run** | A single execution of agent work — either a collaborative session or an autonomous implementation. |
| **Sandbox** | The isolated cloud environment where an agent checks out your repo and works. |
| **Session** | A live, collaborative run where humans and an agent build together in real time. See [Sessions](/concepts/sessions). |
| **Task** | A single unit of work that runs autonomously to a pull request; realized as an [implementation](/concepts/tasks). |
| **Turn** | One unit of agent work within a session; the agent runs one turn at a time while further instructions queue. |
| **UI feedback** | Comments pinned to a live [preview](/configuration/preview) that the agent can act on. See [Reviewing implementations](/guides/reviewing-implementations). |
| **Workspace** | Your team's boundary — it owns repositories, members, and billing. See [Workspaces](/concepts/workspaces). |
