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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral detail beyond that: the result set is all notes for one application, ordered by date, with the exact fields returned. It does not discuss pagination or behavior when no notes exist, which keeps it just short of a 5.

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?

Front-loaded with the decision trigger, then output contents, then follow-up routing — a sensible order. The quoted example phrases are slightly repetitive but they serve the routing function, so waste is minimal.

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 single-parameter read with an output schema and full annotation coverage, the description supplies more than enough to call it correctly. The only unaddressed edge is empty-result behavior, but with an output schema present that is a minor omission.

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% and the single parameter is already documented as the application UUID. The description reinforces the scoping ("for a job application") but adds no syntax or format information beyond the schema, so the baseline 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?

The description states a specific verb and resource — list user-authored notes for a single job application — and enumerates the returned fields (UUID, body, category, timestamp). It is clearly distinguishable from add/update/delete_job_application_note, which are named as separate follow-up steps.

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?

It gives explicit trigger phrasing ("do I have any notes", "show me my notes") and routes the agent onward: use the returned UUIDs with update_job_application_note or delete_job_application_note. That is a concrete when-to-use plus named alternatives, leaving little to inference.

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