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

Annotations already declare readOnlyHint, openWorldHint and destructiveHint=false, covering the safety profile. The description adds only the resource definition and a redundant 'GET /schedules' endpoint note, disclosing no behavioral traits such as pagination, result ordering, or account-scoping behavior.

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 fragments with no filler, and the resource definition is front-loaded ahead of the endpoint reference. Appropriately sized for a simple list tool.

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?

Adequate for a one-param read-only list: annotations cover safety and the schema covers the parameter. However, with no output schema, the description could hint at what a returned schedule contains beyond the brief parenthetical, and it never addresses the account-targeting behavior.

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 single customer_id parameter is fully documented in the schema (100% coverage), including the MSP sub-account semantics. The description adds nothing beyond the schema, which is the expected baseline when coverage is complete.

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 resource (notification schedules) and defines the concept as per-weekday time windows a contact is alerted in, so an agent understands what is listed. The list vs. get_schedule (singular) distinction is implied by the name but never made explicit.

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 list schedules versus fetching one with nodeping_get_schedule, nor prerequisites for the customer_id sub-account path. The agent must infer usage entirely from the name.

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