mark_notification_read

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

Annotations are empty, so the description must disclose all behavioral traits. It states the mutation (mark as read) but does not mention side effects, idempotency, reversibility, or potential errors. The auth requirement is noted, but for a mutation tool, more context is expected.

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 extremely concise with two short sentences. The action is front-loaded in the first sentence, and the auth requirement is appended efficiently. No unnecessary words.

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 simple tool (one parameter, no output schema, no annotations), the description is minimalist. It does not explain return value or error conditions. While the action is clear, the lack of completeness for a mutation tool reduces its effectiveness.

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 description coverage is 0%, meaning the schema provides no descriptions for the single parameter 'id'. The tool description also adds no semantic meaning about what 'id' refers to (e.g., 'ID of the notification'). The parameter's purpose is only implied by the tool name and the integer type.

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 clearly states the action ('Mark') and the resource ('a single notification') with the state change ('as read'). This distinguishes it from sibling tools like 'mark_all_notifications_read' which marks multiple, and 'get_unread_notification_count' which is read-only.

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?

The only usage guidance is the auth requirement ('Requires IWMM_API_KEY'). There is no indication of when this tool should be used versus alternatives (e.g., marking all read), nor any exclusions or prerequisites beyond the API key.

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