get_public_profile

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

No annotations are provided, so the description must carry the behavioral burden. It does disclose that this is a read operation on public data, implying no side effects and likely no authentication. However, it does not mention potential errors, rate limits, or whether the alias is a username or ID. Minimal but not misleading.

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 sentence that is efficient and front-loads the action. No wasted words.

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 with an output schema, the description covers the core action, but it lacks usage guidance and parameter semantics. It does not tell the agent when to choose this over siblings like get_public_list or how to format the alias. The presence of an output schema mitigates some return-format concerns, but the gaps in usage and parameter clarity keep it from being complete.

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%, so the description must explain the alias parameter. It only says 'by alias', which simply echoes the parameter name. It does not define what constitutes an alias (e.g., username, email, numeric ID) or provide format hints. This is insufficient given zero schema documentation.

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 'Read' with a clear resource 'a person's public profile and public lists' and the key parameter 'alias'. This distinguishes it from get_public_list which likely returns a single list, while this covers profile and lists together.

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 guidance on when to use this vs alternatives like get_public_list or get_my_profile. The description only states what it does, leaving the agent to infer usage. Lacks any exclusions or alternative routing.

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