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

Annotations already declare this as a non-readonly, non-idempotent, non-destructive operation, so the safety profile is covered structurally. The description adds one genuinely useful behavioral fact the annotations do not: it requires an Authorization: Bearer bot API key. It does not disclose whether a bid is binding, whether it replaces a prior bid, or how bids are retracted.

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?

Two short sentences, front-loaded with the action and inputs, with the auth constraint placed last. Every clause carries information; 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 mutation tool with no output schema and three required parameters at 0% schema coverage, the description omits too much: it never says what a bid is against (jobId), what the response or side effects are, or how this fits the surrounding job/order workflow exposed by siblings. Adequate only as a one-line summary.

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 0%, so the description carries real weight, and the phrase 'milli-JEY string' adds unit semantics the schema's bare digit pattern does not convey; 'description of the deliverable' clarifies deliverables. However, jobId is never explained (the agent has to guess whether it references an existing job), and the numeric length cap and 5-4000 character deliverables range go unmentioned.

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 states a specific action ('Offer a price... and a description of the deliverable') that maps cleanly to the tool's resource, a job bid, and the title reinforces it. It does not distinguish this from sibling mutation tools such as jey_order_action or jey_post_job, so an agent gets the verb+resource but no sibling contrast.

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?

There is no when-to-use guidance, no statement of prerequisites beyond auth, and no mention of alternatives like jey_post_job or jey_order_action. The agent must infer from the name alone that this is the bidding step of a job workflow.

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