todoist_notification_mark_read

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

With no annotations, the description alone should disclose behavioral traits. It only states the action without details on side effects, permissions, or idempotency, leaving the agent with insufficient information.

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

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

The description is a single sentence without unnecessary words. It is concise, though it could briefly mention that the notification_id must come from a prior list operation to improve clarity without much added length.

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

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

Given the tool's simplicity (one required parameter, no output schema), the description is sufficient to convey the core functionality. The lack of output schema means return values are not needed for basic use.

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

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

Schema coverage is 100% and already describes the 'notification_id' parameter. The description adds no additional meaning beyond the schema, meriting a baseline score of 3.

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

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

The description 'Mark a specific notification as read' clearly states the action and scope, distinguishing it from siblings like 'todoist_notifications_mark_all_read' (marks all) and 'todoist_notifications_get' (retrieves notifications).

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

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

No guidance on when to use this tool versus alternatives (e.g., bulk mark all read) or prerequisites like obtaining a notification_id from 'todoist_notifications_get'.

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