alltrails_get_trail_reviews

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

The description adds behavioral context beyond the readOnlyHint annotation by explaining the compact parameter's effect on the output structure. It does not mention other behaviors like pagination or rate limits, but the annotation already covers safety.

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?

The description is two sentences: first states the purpose, second gives a specific usage tip. No unnecessary words, and the key information is front-loaded.

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?

Given the absence of an output schema, the description explains the compact output but does not detail the full response when compact=false. It covers the essential parameters and purpose, but could be more complete with default response fields.

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?

With 100% schema description coverage, the baseline is 3. The description adds some meaning for the compact parameter by repeating its structure, but it does not provide additional semantic value beyond what the schema already states for the other parameters.

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 clearly states the verb 'Get' and the resource 'user reviews for an AllTrails trail', and identifies the key parameter 'numeric trail id'. This distinguishes the tool from siblings like alltrails_get_trail_photos or alltrails_get_trail_gpx.

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?

The description provides a usage tip about setting compact=true, indicating when to use that option. However, it does not explicitly state when not to use this tool or compare it to alternatives beyond the implied distinction from sibling tools.

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