Create an agent

​

Agent-facing flow

1. Load the Veryfront skill: load_skill({ "skillId": "veryfront" }).
2. Treat this page as the source of truth for the create-agent task. Do not call load_skill({ "skillId": "create-agent" }).
3. The bare Studio starter is for a tool or integration agent by default. If the request is too broad to act on, ask one short form_input with one required brief field for the service/tool and job to automate, then continue from the submitted brief.
4. Inspect only what the brief needs: existing agents, relevant project files, and the integration and MCP tool catalogs.
5. Search integrations before choosing third-party tools. When the brief names or implies a service, call list_integrations with search: "<service>", then call get_integration for exact integration tool IDs and setup details.
6. Use tool_search only to progressively load executable tools for the current run. It is not the agent-authoring catalog. Call tool_search with query: "list_agent_tool_references", then call list_agent_tool_references with the selected project_reference and a capability query or exact names. Use the exact returned name values in tool_ids. The response omits schemas and does not provide provider_tool_ids.
7. Before creating a new Studio project agent, call create_agent_avatar with assign: false, then pass the returned avatar_url into create_agent.
8. Create or update the project agent, re-read or list the agent when a read/list tool is available, then summarize briefly and stop. Report the agent name, id, source path when available, selected integration, and chat action in the final response.

​

Guardrails

• Do not load a removed create-agent sub-skill. Always load veryfront, then this docs page.
• Do not call load_skill({ "skillId": "create-agent" }).
• Do not invent integration IDs, tool IDs, provider tool IDs, files, routes, agents, or capabilities.
• Do not create app, page, route, or chat UI files just to expose an agent. Studio exposes agents directly.

​

Tool selection

• Search integrations with list_integrations, then use exact integration tool IDs returned by get_integration.
• Use tool_search only to progressively load executable tools for the current run. It is not the agent-authoring catalog.
• Load list_agent_tool_references with tool_search, then call it for the selected project and source target. Use exact returned name values in tool_ids. Do not rename, prefix, or infer tool IDs.
• Use list_tools when you need to inspect project-local tool definitions. Use get_integration for integration setup and exact integration tool IDs.
• Use only tool IDs returned by the platform catalog, integration catalog, or current project. Do not invent IDs.
• Put project and integration tools in tool_ids.
• Put provider-native tools in provider_tool_ids.
• Set the prompt with system only. Do not also send system_prompt; it is a compatibility alias.
• For project Knowledge Q&A, include both search_knowledge and get_file in ordinary tool_ids.
• Tell project-knowledge Q&A agents to use search_knowledge for discovery, then use get_file to retrieve body content before answering. search_knowledge returns paths and frontmatter metadata, not file bodies. matched_fields describes metadata matches and can be [] for browse-style results. The agent must say when the project knowledge does not support an answer only after reading relevant candidates or retrying with a refined query.
• Add these rules to the Knowledge Q&A system prompt: “The platform attaches exact source citations automatically after successful get_file reads of knowledge files. Do not write a manual Sources section or retype source paths. Treat returned source paths as opaque identifiers. If you mention one inline, copy it character-for-character from the latest search_knowledge or get_file result; never shorten, normalize, or reconstruct it.”
• Do not use knowledge_lookup. It is a legacy internal helper, not a project-agent tool.
• Choose the smallest useful tool set for the brief.
• Do not create a role-only helper unless the user explicitly asks for a no-tool or no-integration agent.
• Do not create app, page, route, or chat UI files just to expose an agent; Studio exposes agents directly.

​

Agent shape

• a concise name and description
• a short system prompt with scope, capabilities, guardrails, and response style
• a model and step limit appropriate for the task
• a few practical suggestions
• only the tools required by the brief
• an avatar_url from create_agent_avatar for new Studio project agents
