Agents Endpoint Object Structure

This page applies to the agents endpoint.

Example

Agents Endpoint
endpoints:
  agents:
    recursionLimit: 50
    maxRecursionLimit: 100
    disableBuilder: false
    # (optional) Agent Capabilities available to all users. Omit the ones you wish to exclude. Defaults to list below.
    # capabilities: ["execute_code", "file_search", "actions", "tools", "artifacts", "ocr", "chain", "web_search"]
    # (optional) File citation configuration for file_search capability
    maxCitations: 30          # Maximum total citations in responses (1-50)
    maxCitationsPerFile: 7    # Maximum citations from each file (1-10)
    minRelevanceScore: 0.45   # Minimum relevance score threshold (0.0-1.0)

This configuration enables the builder interface for agents.

recursionLimit

KeyTypeDescriptionExample
recursionLimitNumberSets the default number of steps an agent can take in a run.Controls recursion depth to prevent infinite loops. When limit is reached, raises GraphRecursionError. This value can be configured from the UI up to the maxRecursionLimit.

Default: 25

Example:

endpoints / agents / recursionLimit
recursionLimit: 50

For more information about agent steps, see Max Agent Steps.

maxRecursionLimit

KeyTypeDescriptionExample
maxRecursionLimitNumberSets the absolute maximum number of steps an agent can take in a run.Defines the upper limit for the recursionLimit that can be set from the UI. This prevents users from setting excessively high values.

Default: If omitted, defaults to the value of recursionLimit or 25 if recursionLimit is also omitted.

Example:

endpoints / agents / maxRecursionLimit
maxRecursionLimit: 100

For more information about agent steps, see Max Agent Steps.

disableBuilder

KeyTypeDescriptionExample
disableBuilderBooleanControls the visibility and use of the builder interface for agents.When set to `true`, disables the builder interface for the agent, limiting direct manual interaction.

Default: false

Example:

endpoints / agents / disableBuilder
disableBuilder: false

allowedProviders

KeyTypeDescriptionExample
allowedProvidersArray/List of StringsSpecifies a list of endpoint providers (e.g., "openAI", "anthropic", "google") that are permitted for use with the Agents feature.If defined, only agents configured with these providers can be initialized. If omitted or empty, all configured providers are allowed.

Default: [] (empty list, all providers allowed)

Note: Must be one of the following, or a custom endpoint name as defined in your configuration:

  • openAI, azureOpenAI, google, anthropic, assistants, azureAssistants, bedrock

Example:

endpoints / agents / allowedProviders
allowedProviders:
  - openAI
  - google

capabilities

KeyTypeDescriptionExample
capabilitiesArray/List of StringsSpecifies the agent capabilities available to all users for the agents endpoint.Defines the agent capabilities that are available to all users for the agents endpoint. You can omit the capabilities you wish to exclude from the list.

Default: ["execute_code", "file_search", "actions", "tools", "artifacts", "ocr", "chain", "web_search"]

Example:

endpoints / agents / capabilities
capabilities:
  - "execute_code"
  - "file_search"
  - "actions"
  - "tools"
  - "artifacts"
  - "ocr"
  - "chain"
  - "web_search"

Note: This field is optional. If omitted, the default behavior is to include all the capabilities listed in the default.

maxCitations

KeyTypeDescriptionExample
maxCitationsNumberControls the maximum total number of citations that can be included in a single agent response.When using file_search capability, limits the total number of source citations returned to prevent overwhelming responses while ensuring comprehensive coverage.

Default: 30

Range: 1-50

Example:

endpoints / agents / maxCitations
maxCitations: 30

maxCitationsPerFile

KeyTypeDescriptionExample
maxCitationsPerFileNumberLimits the maximum number of citations that can be extracted from any single file.Ensures citation diversity by preventing any single file from dominating the citations, encouraging representation from multiple sources.

Default: 7

Range: 1-10

Example:

endpoints / agents / maxCitationsPerFile
maxCitationsPerFile: 7

minRelevanceScore

KeyTypeDescriptionExample
minRelevanceScoreNumberSets the minimum relevance score threshold for sources to be included in responses.Filters out low-quality matches based on vector similarity scores. Higher values (e.g., 0.7) ensure only highly relevant sources are cited, while lower values (e.g., 0.0) include all sources regardless of quality.

Default: 0.45 (45% relevance threshold)

Range: 0.0-1.0

Example:

endpoints / agents / minRelevanceScore
minRelevanceScore: 0.45

File Citation Configuration Examples

Default Configuration (Balanced)

endpoints:
  agents:
    maxCitations: 30
    maxCitationsPerFile: 7
    minRelevanceScore: 0.45

Provides comprehensive citations while preventing overwhelming responses and filtering out low-quality matches.

Strict Configuration (High Quality)

endpoints:
  agents:
    maxCitations: 10
    maxCitationsPerFile: 3
    minRelevanceScore: 0.7

Only includes highly relevant citations with strict limits for focused responses.

Comprehensive Configuration (Research)

endpoints:
  agents:
    maxCitations: 50
    maxCitationsPerFile: 10
    minRelevanceScore: 0.0

Maximum information extraction for exhaustive research tasks, including all sources regardless of relevance.

Agent Capabilities

The capabilities field allows you to enable or disable specific functionalities for agents. The available capabilities are:

  • execute_code: Allows the agent to execute code.
  • file_search: Enables the agent to search and interact with files. When enabled, citation behavior is controlled by maxCitations, maxCitationsPerFile, and minRelevanceScore settings.
  • actions: Permits the agent to perform predefined actions.
  • tools: Grants the agent access to various tools.
  • ocr: Enables uploading files as additional context, leveraging Optical Character Recognition for extracting text from images and documents.
  • web_search: Enables web search functionality for agents, allowing them to search and retrieve information from the internet.

By specifying the capabilities, you can control the features available to users when interacting with agents.

Example Configuration

Here is an example of configuring the agents endpoint with custom capabilities and file citation settings:

Agents Endpoint
endpoints:
  agents:
    disableBuilder: false
    # File citation configuration
    maxCitations: 20
    maxCitationsPerFile: 5
    minRelevanceScore: 0.6
    # Custom capabilities
    capabilities:
      - "execute_code"
      - "file_search"
      - "actions"
      - "artifacts"
      - "ocr"
      - "web_search"

In this example:

  • The builder interface is enabled
  • File citations are limited to 20 total, with maximum 5 per file
  • Only sources with 60%+ relevance are included
  • The agent has access to code execution, file search (with citations), actions, artifacts, OCR, and web search capabilities

Notes

  • It’s not recommended to disable the builder interface unless you are using modelSpecs to define a list of agents to choose from.
  • File citation configuration (maxCitations, maxCitationsPerFile, minRelevanceScore) only applies when the file_search capability is enabled.
  • The relevance score is calculated using vector similarity, where 1.0 represents a perfect match and 0.0 represents no similarity.
  • Citation limits help balance comprehensive information retrieval with response quality and performance.
