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

With no annotations, the description carries the full burden and does disclose the key financial behavior: funds are escrowed immediately from the caller's balance and released only upon approval. It omits failure/reversal behavior (cancellation, dispute, refunds) and permission requirements, so it stops short of full disclosure.

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?

Three tight sentences, front-loaded with the core action and immediately followed by the consequential escrow/release mechanics. No filler.

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?

For a financially consequential mutation with no annotations and no output schema, the description covers the essential money flow (escrow now, release on approval) and the optional milestone split. It leaves edge cases such as cancellation or dispute outcomes unexplained.

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 all four parameters are already documented, including the milestone sum-to-bid constraint. The description restates the milestone rule but adds no format or syntax detail beyond the schema, so baseline 3 applies.

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?

States a specific actor (poster), verb (accepts), and resource (one bid), which cleanly separates it from jobs_bid (placing a bid) and jobs_approve (approving delivery). The reference to approving delivery further delineates it from the downstream approval step.

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 makes clear this is the poster's action on a received bid and frames approval as a separate later step, giving strong context. It does not, however, explicitly name alternatives or state when-not-to-use (e.g., before delivery, or in lieu of jobs_approve).

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