notion_query_view

Read-onlyIdempotent

Retrieve data from a Notion database view using the project's governed connector, ensuring reads are authorized and tied to the correct account and project context.

Instructions

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

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.

C2.7/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the bar is lower. The description adds useful context about governed-connector routing and that Spring verifies the effect. However, the approval_ref note 'when resuming a write' introduces a write concept that sits awkwardly with the read-only effect and could confuse agents.

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 uses a clear bullet list for parameters. The first two lines are slightly label-like, but the overall structure is scannable and has no wasted prose.

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

Completeness2/5

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

For a connector wrapper with an opaque arguments string and no sibling differentiation, the description is incomplete. An agent cannot tell what a view query needs (e.g., a view ID or filter payload) or when this tool is the correct choice. The output schema and annotations help, but the core operational semantics are absent.

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

Parameters4/5

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

With 0% schema description coverage, the description compensates by giving each parameter a meaningful role: effect must be read, arguments is a JSON string, project_id is a UUID, connector_account_ref is a project-bound alias. The main weakness is that 'arguments' remains opaque—the required keys for the underlying query_view operation are not specified.

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 opens by restating the tool name ('Notion connector operation `query_view`') without explaining what querying a view does or returns. It never states that this queries a Notion view or how it differs from sibling tools like notion_query_data or notion_query_database. The only added line is about routing authority, which is a constraint, not a purpose.

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 when-to-use guidance or alternatives are given. The sentence 'Routes only through the exact project/account governed connector authority' describes a constraint, not the situations where an agent should select this tool over siblings. There is no mention of when query_view is preferable to notion_query_data or notion_search_intelligent.

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