upwork_submit_proposal

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

No annotations are provided, so the description carries the full burden. It discloses that the action is sensitive, spends Connects, and returns submission status and connects used. This is good behavioral context beyond the basic action.

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 very concise: one sentence for purpose, a warning, and expected output. No unnecessary words, front-loaded with the key action.

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 no output schema, the description mentions return values (status and connects used). It covers the essential aspects for a submission tool, though more detail on error handling could be beneficial. Still, it is reasonably 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?

The input schema has 100% description coverage, so the description adds little beyond naming 'cover letter and rate/bid'. It does not elaborate on the parameters further, meeting the baseline but not adding extra value.

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 action 'Submit a proposal to an Upwork job' with a specific verb and resource. It distinguishes from sibling tools like upwork_get_proposals and upwork_withdraw_proposal by focusing on the submission action.

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 includes an important warning about spending Connects and ensuring correctness, which provides cautionary context but does not explicitly compare to alternatives or state when not to use this tool. It implies usage when submitting a proposal but lacks direct guidance on selecting among siblings.

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