get_public_portfolio

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

No annotations are provided, so the description carries the full burden. 'View' and 'public' imply a read-only operation on publicly accessible data, which is useful behavioral context, but the description does not confirm authentication requirements, error behavior, or rate limits.

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. Every word earns its place, and the key action and input are immediately clear.

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 one-parameter read tool, the description covers the essential purpose and input. However, with no annotations and no output schema, it could be more complete by clarifying that no authentication is needed for public portfolios or by hinting at what portfolio data is returned.

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 description coverage is 100%, so the single identifier parameter is already well documented. The description mirrors the schema's 'username or slug' detail but adds no further meaning or syntax guidance beyond what the schema provides; baseline 3 is appropriate.

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 states a specific verb ('View'), resource ('someone's public portfolio'), and input mechanism ('by their identifier'). The 'someone's public' phrasing implicitly distinguishes this from tools like get_profile that likely return the caller's own profile, but it does not explicitly name any sibling alternative.

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?

There is no explicit when-to-use or when-not-to-use guidance, nor any mention of alternative tools such as get_profile or get_portfolio_analytics. The context is implied only by the word 'someone's', which is insufficient to route the agent confidently.

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