Get profile

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered externally. The description adds nothing beyond that: no note on auth requirements, what a profile contains, or behavior when the ID does not exist.

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, which is appropriate structurally. It reads as under-specification rather than genuine conciseness given how little it conveys.

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 simple read tool this is close to the minimum, but with no output schema and no description of the returned profile shape, or which entity a 'profile' is, the agent cannot confidently call it against the right sibling.

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% and the single required parameter carries only minLength. 'By ID' echoes the schema field rather than explaining the identifier's format, source, or valid values, so the parameter remains semantically thin.

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 verb ('Get'), resource ('Reddit profile'), and shards out the key ('by ID'), so the basic action is legible. However, 'profile' is ambiguous in this API family, which also exposes get_me, list_account_profiles and list_business_profiles, and the description offers no differentiation from those.

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?

No when-to-use context, no alternative named, no prerequisites. With several sibling tools returning profile-like data, the agent is left to guess which one applies.

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