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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world, so the safety profile is covered. The description adds useful content scope (landing copy, FAQ, nearby places, DJ/event counts), but says nothing about what happens with an unknown slug, whether counts are live or cached, or any response shape detail.

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 compact sentences with no waste; the content scope is front-loaded and the usage hint follows. The second sentence is slightly conversational ('what a DJ costs in a given city') but it still carries real guidance.

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 must convey return content, and it does so reasonably by enumerating the copy fields and the two counts. It leaves error behavior for an invalid or unknown place key unaddressed, which is a minor gap for a single-parameter read tool.

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?

There is a single required parameter with 100% schema coverage, and the schema already says it comes from list_locations. The description adds no syntax, format, or key-vs-slug distinction beyond what the schema states, 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?

The description uses a specific verb-resource framing: it returns 'one place with its landing copy' including display name, FAQ, nearby places, plus DJ and live-event counts. That is clearly distinct from list_locations or get_dj, though it never names those siblings to sharpen the contrast.

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 offers a concrete scenario ('local questions like what a DJ costs in a given city'), which implies when to reach for it. However, it gives no exclusions or explicit alternative, and the natural alternative for browsing places, list_locations, is only mentioned inside the schema, not in the description.

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