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

With no annotations, the description carries the full burden and does well: it discloses that validation is automatic and immediate, states the two validation conditions (own-domain page, word-for-word quote), and describes the reward on success (credit passes for four sibling tools). What happens on failure (error shape, retry, rejection handling) is left unstated.

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 with the action and audience front-loaded, followed by validation criteria and the reward. No filler and no repetition of the name or title.

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 four-required-parameter mutation with no annotations and no output schema, the description covers purpose, validation, and the success outcome. The main gap is the failure path and any response detail, but what an agent needs to submit correctly is largely present.

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 75% and the description reinforces two of the documented parameters meaningfully: 'url' must be on the builder's own site and 'quote' must match the page word for word, which adds constraint detail beyond the schema text. The 'claim' parameter remains undocumented in both the schema and the description.

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 ('submit a claimed job') and names the audience ('Contractors'), so it is distinguishable from the reference and listing siblings. It never names a sibling like claim_job or check_credit to clarify the boundary, so it stops short of full differentiation.

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?

Gives clear context and prerequisites for use (you must have a claimed job whose page sits on the builder's own site and quotes the price verbatim). It does not state when NOT to use it or point to an alternative such as claim_job, so no exclusions are offered.

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