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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral value beyond that: it explains the return semantics around secrets — only the secret NAME is exposed, never a credential value. That is a meaningful disclosure for an agent reasoning about data exposure, though return shape and pagination remain unspecified.

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?

Two tight sentences, front-loaded with the action and resource, and the second sentence earns its place by clarifying the secret-exposure behavior. No filler.

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 read-only list tool with annotations covering safety and no output schema, the description covers purpose and the key secret-handling nuance. However, with 0% schema coverage it leaves both parameters and any return/pagination detail unexplained, making it minimally adequate rather than complete.

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% and both parameters (limit, project_id) are undocumented in the schema. The description implies project scoping via 'a project's' but says nothing about the limit parameter or any defaults/pagination behavior, so it only partially compensates for the coverage gap.

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?

States a specific verb and resource scoped to a project ('List a project's notification channels'), which clearly separates it from create/set/delete siblings sharing the notification-channel resource. It does not explicitly distinguish itself from list_notification_templates, but the resource noun is precise.

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 call this versus alternatives such as list_notification_templates or list_secrets, and no mention of prerequisites or required permissions. The agent must infer usage from the name alone.

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