notion_list_data_source_templates

Read-onlyIdempotent

Lists available Notion data source templates, enabling users to view and select template options for data integration configuration.

Instructions

Notion connector operation list_data_source_templates (platform tool notion.list_data_source_templates).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

C2.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already carry the safety profile (readOnlyHint=true, idempotentHint=true, destructiveHint=false), lowering the burden on the description. The description adds useful context: routing only through governed project/account authority, effect must be 'read' and is verified by Spring, and approval_ref's write-resume role. The 'resuming a write' phrase describes the platform-level parameter rather than this read operation, so there is no contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and well-structured, front-loading identity and routing before the parameter block. The opening line is partially redundant with the tool name and platform prefix, but the Args section earns its place by compensating for the 0% schema description coverage.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Parameter semantics and routing governance are well covered, and the presence of an output schema relieves the need to describe return values. However, the description omits what a data source template is and provides no differentiation from adjacent Notion listing tools, leaving an agent to guess at the tool's actual purpose.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the full burden — and it delivers: all 7 parameters (arguments, project_id, project_ref, connector_account_ref, idempotency_key, effect, approval_ref) receive a semantic gloss. Effect is explicitly constrained to 'read' with Spring verification, and idempotency_key's purpose as a stable business-action identity is clarified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description restates the operation name ('Notion connector operation list_data_source_templates') without explaining what a data source template is, what listing them yields, or how this differs from sibling tools like notion_list_data_sources. The only added context is routing authority, which says nothing about the tool's actual function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to call this tool versus alternatives such as notion_list_data_sources, notion_query_data_source, or notion_query_view. The routing sentence is a constraint, not usage direction, so an agent cannot distinguish which Notion listing operation to choose from this description alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
