upwork_get_proposal_details

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

No annotations are provided, so the description must carry the full burden. It states the tool returns details (cover letter, bid, messages) but does not mention whether it is read-only, any required authentication, or rate limits. For a retrieval tool, this is passable but not explicit about safety characteristics.

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, front-loading the purpose and effectively listing key return items. No fluff or redundant information.

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 a single parameter and no output schema, the description sufficiently covers what the tool does and what it returns. However, it omits potential error conditions (e.g., invalid URL) or privacy considerations, keeping it from a perfect score.

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?

The input schema already describes the single parameter 'proposal_url' with 100% coverage, so the description adds no additional semantic value. The baseline of 3 is appropriate; no extra format or constraints are provided beyond what the schema states.

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 tool retrieves detailed information about a specific proposal, using the verb 'Get' and the resource 'proposal details.' This unequivocally distinguishes it from sibling tools like upwork_get_proposals (which lists proposals) and upwork_get_contract_details (different resource).

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 does not explicitly state when to use this tool versus alternatives, such as when you need details on a single proposal vs. listing all proposals. While the purpose is clear, the lack of guidance on prerequisites (e.g., needing a valid proposal_url) or exclusions leaves room for ambiguity.

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