Go to **Forge > Agents** and click **Create Agent**. ### Basic Setup * **Name & Description**: Clearly identify the agent's purpose. The description does double duty, it helps you organize, and it's used as a routing signal whenever this agent is invoked as a [sub-agent](/build/agents/capabilities/subagent). * **Execution Mode**: How the agent processes each request, **Reasoning** (full planning loop, the default) or **Route** (single-step capability selection). This is part of the agent's identity, set here at build time; you can change it later from the agent's **Configuration** tab, but not per-request. See [Execution Mode](/build/agents/execution_mode). * **Application**: Associate the agent with an Application. This determines which context documents are available and where the agent's LLM traffic (including its [flow steps](/build/agents/agent_flow)) is monitored. * **Base URL (Optional)**: A default host applied to all of this agent's [API Actions](/build/agents/capabilities/api_action), so individual actions only need relative paths. Actions can override it when needed. ### Drafts, versions, and releases Agents are versioned. Edits in the Portal land on the agent's **draft**; when you're happy with it, **Publish** creates an immutable version (major / minor / patch, with release notes). You can label versions with named releases like `prod` and pin requests to a version or release from the SDK, unpinned requests run the current draft. Manage versions from the agent's **Versions** tab; see [Agent Call](/sdk/agent_call) for pinning from code. ## Next * Configure how it executes: [Execution Mode](/build/agents/execution_mode) * Add tools/capabilities: [LLM Action](/build/agents/capabilities/llm_action) · [API Action](/build/agents/capabilities/api_action) · [Subagent](/build/agents/capabilities/subagent) * Full walkthrough: [Build an Agent](/examples/build_agent) * Call your agent from code: [Agent Call](/sdk/agent_call)
