github_list_notifications

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

The Args section adds behavioral context (default is unread only, participating filter, max results), but without annotations the description lacks disclosure of side effects, whether notifications are marked as read, or auth requirements beyond the phrase 'authenticated user'.

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 front-loaded with a clear one-sentence purpose, followed by a structured Args block. The Args section repeats schema names but adds value with descriptions, so it earns its place without being verbose.

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?

For a simple list operation, the description covers the essential purpose, parameter meanings, and defaults. An output schema exists, so return value details are not required. It could mention pagination or result structure, but overall it is adequate.

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?

The description's Args section provides clear semantic meaning for each parameter (e.g., 'all_notifications: Show all notifications including read ones'), compensating for the 0% schema description coverage. It explains defaults and filtering behavior beyond the bare schema.

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 uses a specific verb 'List' and identifies the resource 'GitHub notifications for the authenticated user.' It clearly distinguishes from sibling tools like github_mark_notifications_read (which marks read) and other list tools.

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 explicit guidance on when to use this tool versus alternatives. While the sibling list includes github_mark_notifications_read, the description does not mention when to use this as opposed to marking notifications read or other notification-related operations.

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