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 adds real value beyond that by naming the required auth scope (job-application-notes:read) and confirming the response includes a sensitive flag, which an agent may need to treat carefully.

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?

One front-loaded sentence covering purpose and payload, followed by a compact endpoint/scope line. No filler, no repetition of schema content, and the most decision-relevant information (what is listed, on what) comes first.

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?

With no output schema, the description compensates well by enumerating the returned fields, and the schema handles pagination and the required id. It stops short of noting ordering or behavior on an unknown/invalid application id, which would fully close the loop.

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 page, perPage and job_application_id are already documented in the schema. The description adds no syntax or format detail beyond restating that the id targets an application, so the baseline of 3 applies.

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 (List) and resource (notes on one application), and enumerates the returned fields: id, author display name, text, sensitive flag, timestamps. This clearly separates it from the write-side sibling homerun_add_note and from other list tools in the family.

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 phrase 'on one application' implies the required scoping context, so an agent can infer this is the per-application notes reader. However, there is no explicit when-to-use/when-not guidance and no routing to alternatives (e.g., when to prefer a general application fetch). Usage is implied rather than stated.

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