ONE TASK THROUGH BUILDER
Build a release agent in one project.
Start with instructions for drafting release notes. Add a GitHub connection, a Slack channel, and an approval rule for anything the agent posts.
Run a local test, inspect the tool calls, add an evaluation case, and deploy the same project. Builder keeps the project files, live events, and approval state together.
- 01Write the instructions
- 02Add tools and connections
- 03Test and evaluate
- 04Deploy the project
- 05Inspect the run
01
Keep a growing agent clear.
Builder keeps instructions, models, tools, skills, channels, account connections, automations, evaluations, deployment, and live runs visible in one project.
Build
02Keep the whole project visible.
Create an agent or open an Assembly Line project. Set its identity and instructions, choose a model, add skills and tools, set approval rules, connect channels, grant provider access, and choose its infrastructure.
- ↳Agent identity, instructions, model, and context
- ↳Typed tools and approval policies
- ↳Skills and allowed-tool boundaries
- ↳Channels and provider connections
- ↳Automations, sandboxes, and infrastructure adapters
Test
03Catch problems before deployment.
Chat with the local runtime, inspect run events, resolve approvals and questions, and turn useful conversations into repeatable evaluation cases.
- ↳Local streaming chat
- ↳File attachments
- ↳Approval and question handling
- ↳Evaluation cases and suites
- ↳Tool mocks, assertions, and baselines
Deploy
04Deploy the project you tested.
Builder reads deployment settings, checks infrastructure and credentials, and guides the deployment. Each revision points to an explicit project state.
- ↳Deployment preflight
- ↳Environment and secret configuration
- ↳Revision history
- ↳Local and hosted environment separation
Operate
05Know what the agent is doing.
Inspect runs, timelines, tool calls, approvals, errors, and runtime state. Start a hosted chat, cancel a run, answer a question, or resume an approved action.
- ↳Run history and detail
- ↳Live event streaming
- ↳Tool-call inspection
- ↳Approval, answer, cancel, and resend controls
- ↳Connection authorization against the active runtime
06
Pair a hosted agent with a Mac.
Builder can install and pair Assembly Line Computer Host for agents that control a Mac. End-to-end encrypted tool calls move through a device relay while the runtime remains hosted.
07
Files remain the contract.
Tools stay in TypeScript. Instructions and skills stay in Markdown. Evaluations and deployment settings stay in the project. Open it in Builder, a code editor, a coding agent, or Git.
QUESTIONS, ANSWERED
What to know before you start.
01Is Builder a no-code agent platform?＋
Builder provides a visual way to build and configure Assembly Line agents. The project files remain the source, so developers can move between Builder and code.
02Does it work with existing agents?＋
Builder opens an Assembly Line folder, builds its interface from the project files, and preserves files it does not model.
03Can it operate hosted agents?＋
Yes. Builder supports hosted chat, streamed run inspection, approvals, answers, cancellation, and connection authorization.
04Must a hosted agent run on my Mac to control it?＋
No. Computer Host pairs a hosted agent with a Mac through an encrypted device relay.
