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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description contributes the return shape (seven weekday entries) and the underlying GET path, which is modest but real added context. It says nothing about behavior when the named schedule does not exist.

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 short sentences, front-loaded with what is returned and then the endpoint path. No filler; every clause carries information. Slightly clipped rather than padded.

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 two-parameter read with full annotation coverage and no output schema, the description is largely sufficient: it states the input identity key and the return contents. It omits any note on failure modes (unknown schedule name) or the meaning of the optional customer_id, leaving minor gaps.

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 100%, so the baseline is 3. The description's 'for example Days or All' gives the agent concrete sample values for the name parameter, which is genuinely useful beyond the schema's bare 'Schedule name.', but it says nothing about the customer_id sub-account parameter.

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?

Names a specific verb+resource ('One notification schedule by name') and even describes the payload shape ('seven weekday entries'), which an agent can act on. It does not explicitly contrast with siblings like nodeping_list_schedules or nodeping_put_schedule, so it stops short of a 5.

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?

There is no when-to-use guidance, no mention of list_schedules as the alternative for browsing, and no stated prerequisite (e.g. that the name must already exist). The single-schedule-by-name framing only weakly implies usage, and nothing tells the agent how to choose between this and list_schedules.

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