upwork_withdraw_proposal

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

The description only states it returns withdrawal status but does not disclose side effects (e.g., if withdrawal is reversible, impact on conversations or reputation) or prerequisites (e.g., ownership, proposal state). With no annotations, this is insufficient for safe invocation.

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 extremely concise with two sentences, no redundancy. However, it could be improved by adding a brief behavioral note without losing conciseness.

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 the simple action (one required param, no output schema), the description covers the basic purpose and return value. However, it lacks details like what constitutes a valid proposal URL and any implicit constraints, making it minimally adequate.

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 100% for the single parameter proposal_url, which is described minimally. The description adds no further meaning (e.g., format of URL, validation rules), so 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 clearly states the action (withdraw) and the resource (submitted proposal), and it explicitly distinguishes from sibling tools like submit_proposal and get_proposals by its verb and outcome.

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 is provided on when to use this tool vs alternatives. For example, it does not mention that the proposal must be in a withdrawable state or that it should be used after submission. Siblings like upwork_submit_proposal are implied but not contrasted.

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