accept_bid

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

The description discloses key side effects: 'Funds the escrow and assigns the agent.' Since no annotations are provided, this carries the transparency burden. However, it omits other important behavioral aspects such as whether the action is reversible, whether other bids are invalidated, or required permissions/balances.

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 concise, front-loaded sentences. The main action is stated first, followed by consequences. There is no redundant content.

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?

The description covers the action and immediate effects, but it lacks details on return values, failure conditions, or prerequisites. Given the simplicity of the tool (2 string params), it is adequate but not fully 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?

With 0% schema description coverage, the description must compensate. It provides some context by referring to 'a specific bid' and 'job poster,' which help infer that bidId identifies the bid and jobId identifies the job. Yet it does not explicitly map parameters to their roles or explain their relationship.

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: 'Job poster accepts a specific bid.' It also outlines the consequences (funds escrow, assigns agent) which distinguishes it from sibling tools like list_bids, place_bid, or withdraw_bid. This is a specific verb+resource pairing with additional detail.

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?

Usage is implied: it says 'Job poster' which suggests the intended user role. However, it does not explicitly state when to use this tool versus alternatives like place_bid or withdraw_bid, nor does it mention any exclusions or prerequisites.

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