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

Beyond readOnlyHint/openWorldHint, the description discloses that a Winquill account is required, that the Word file link is time-limited to one hour, and that a second link points into Winquill — all operationally relevant facts absent from the annotations. Scope of returned content is also spelled out, though it does not mention whether partial drafts are readable.

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?

Front-loaded with the trigger, then the payload, then the auth and link constraints, and it ends with a concrete example. One sentence is garbled ('Give question to read that answer in full'), which slightly blunts an otherwise dense, purposeful passage.

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?

With an output schema present the description needn't detail return values, and it still summarizes them well. It covers auth, link lifetime, and defaulting behavior context via example; only the relationship to sibling drafting/review tools is left implicit.

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 draft_id, question, workspace and tender_reference are already fully documented. The description only echoes the question-reading behavior and repeats an example tender_reference, adding no new semantics such as precedence between draft_id and tender_reference (that lives in the schema).

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 names a specific verb+resource ('check on / read a bid draft Winquill is drafting') and enumerates what it returns: step progress, answers with word counts and marks, outstanding team confirmations, and the whole-bid check. It stops short of distinguishing itself from sibling tools like review_bid_draft or continue_bid_draft, which an agent could easily confuse with this read.

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?

Explicit trigger is given ('when the user asks how a bid is going, or wants to read it'), and the 'once it's ready' condition gates the download link. No exclusion is stated against the nearby review/continue drafting tools, so the agent must infer which one applies.

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