Get a freelancer profile

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

Annotations already provide readOnlyHint and openWorldHint, so the safety profile is covered. The description adds that the profile is public and that exactly one freelancer is returned, but it does not discuss not-found behavior or any additional fetch semantics. This is adequate but not rich.

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 a single short sentence with no filler. It front-loads the key information: public profile, one freelancer, and lookup by ID.

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-only lookup with annotations covering safety and open-world behavior, the description is nearly complete. It could mention how to obtain the freelancer_id or what happens if the profile does not exist, but those are not essential for correct invocation.

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 0%, so the description carries the burden for parameter meaning. It does say 'by id,' which maps to freelancer_id, but it adds little beyond what the property name and integer schema already communicate. The parameter is simple, but the description does not meaningfully enrich it.

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 uses a specific verb and resource: 'Public profile of one freelancer by id.' It clearly states the cardinality and lookup key, making it easy to distinguish from sibling tools like get_employer or get_workspace.

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 clearly implies this is for fetching a single public freelancer profile by ID. It does not explicitly name alternatives or exclusions, but the context is clear enough for an agent to know when to select this tool.

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