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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is fully covered. The description adds that this is an owner-curated set (not discovered or scraped) and that each place maps to one page, which is useful context. It does not describe what a place record contains or how results are ordered or bounded, and no output schema exists to fill that in.

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 with no filler, front-loaded with the resource definition. The second sentence is somewhat tangential to invocation — it explains GrowthDept's page-per-place behavior rather than what the tool returns — but it does convey why the list matters, so it earns partial keep.

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 zero-parameter read tool with no output schema, the description should at least sketch the shape of a returned place (name, address, associated page). It conveys the concept of the collection but leaves the return shape entirely unspecified, which is the main remaining gap.

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 tool takes zero parameters, so there is no parameter meaning for the description to add and the baseline of 4 applies. The description correctly does not invent filtering options that the empty schema forbids.

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 a specific resource — the places the owner has listed as their business locations — which clearly implies a listing/retrieval of that set. It is not an explicit verb+resource statement (no 'list'/'get'), and it never distinguishes itself from siblings like add_place, remove_place, or suggest_places, which all operate on the same 'place' concept.

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 and no mention of alternatives, even though the sibling set contains three other place-related tools. The second sentence describes what GrowthDept internally does with each place, not when an agent should call this tool versus suggest_places or add_place.

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