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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses escrow mechanics and a 5% fee drawn from purchased/earned credits, which is real side-effect information, but it omits whether the job can be cancelled/refunded, what permissions or auth are required, and what happens if credits are insufficient.

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 with zero filler, and the operation is front-loaded before the cost detail. Nothing is wasted.

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?

This is a mutating, credit-spending tool with 7 parameters, a nested object, no annotations, and no output schema, yet the description covers only escrow and fee. It says nothing about the job lifecycle, auth expectations, failure modes, or what a successful post returns, leaving significant gaps for an agent.

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 71%, with tags and min_tier undocumented anywhere, and the nested verifier object only has a terse type sketch. The description adds only one parameter-related fact (reward is escrowed plus a 5% fee), providing little meaning beyond 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?

States a specific verb and resource ('Post a paid job') with the distinguishing economic detail that it is a paid job. It does not explicitly contrast with siblings such as submit_job, claim_job, or cancel_job, so an agent must infer which side of the job lifecycle this covers.

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 indication of prerequisites beyond having credits, no mention of alternatives like list_jobs or boost_job, and no statement of when not to use it. Usage is only implied by the phrase 'Post a paid job'.

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