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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower, and the description goes beyond them by detailing the returned payload and the tent-only fields that may or may not appear. It stops short of stating anything about failure modes (e.g., invalid or stale id) or that results are a single item, not a list.

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 verb and scope, and both sentences carry real information. The first sentence is long and clause-heavy, but each clause identifies a distinct returned field rather than padding, so it stays justified.

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?

There is no output schema, so the description must carry the return-value burden, and it does — naming the review summary, specs, pros/cons, stockists, and the conditional tent fields. Combined with complete parameter docs and annotations, an agent has everything needed to call it and set user expectations.

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 100% and both parameters are documented in the schema, including the enum and the advice to pass kind. The description only reinforces the provenance of id ('one item from find_gear') without adding format or edge-case detail, 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?

States a specific verb (get) and resource (gear details) and enumerates exactly what is returned: review summary, specs, pros/cons, retailers, plus tent-specific extras. It explicitly frames itself relative to find_gear, so an agent can separate it from that sibling without reading either schema.

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?

Gives explicit when-to-use conditions: after find_gear when the user narrows to one item, wants a detailed two-item comparison, or wants alternatives to a tent. It names the prerequisite tool (find_gear) and even prescribes how to present alternatives (one sentence on the key tradeoff).

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