The person's notes

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description does add useful behavioral context about the returned payload — per-note status, a plain status line, and the reply thread with Kadal — which matters because no output schema exists. It still omits scoping (own notes only?), pagination, and result volume, so it stops short of full disclosure.

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?

A single front-loaded sentence with no filler. Slight ambiguity comes from internal jargon ('plain status line', 'Kadal's replies') that may not be self-explanatory, but nothing is redundant or bloated.

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 and no parameter descriptions, the description does well to sketch the returned fields. However, for a listing tool with filtering it should clarify filtering semantics and result scope/limits; the unexplained reference to 'Kadal' and the missing notion of whose notes these are leave real 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 coverage is 0% for the single optional 'status' parameter, so the description must carry it. It merely re-lists the enum values in a phrase that reads as an output field ('with each one's status...') rather than explaining that status is an input filter, that it is optional, and what happens when it is omitted. This ambiguity risks the agent treating it as a return value instead of a filter.

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 identifies the resource as 'the person's notes (reports) on products' and enumerates part of its shape, so an agent can grasp what it deals with. But it never states the operation (list/retrieve) explicitly and does not distinguish it from the sibling report_problem, which also concerns problem reports. Purpose is inferable but not crisply differentiated.

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 at all: nothing says to call this to review your own submitted reports rather than to search_products or report_problem. No exclusions, prerequisites, or alternative routing are given, leaving the agent to guess 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.
