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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered externally. The description adds the meaningful caveat that publishing must be explicitly requested, reinforcing the destructive nature, but does not say what exactly is destroyed, what happens on repeat calls, or what authorization the 'authenticated solver' requires.

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 tight sentences with no filler, and the core operation is front-loaded ahead of the publishing caveat. Efficient, though the terse phrasing leans on unexplained jargon.

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 five-parameter, fully-required mutation with no output schema, zero schema coverage, and an open-world destructive profile, the description is too thin. It omits parameter meaning and workflow placement, leaving an agent under-informed about the inputs it must supply.

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% across five required parameters (id, round, network, bounty_contract, publish_files). The description only alludes to publish_files ('Publish files only when explicitly requested') and never explains id, round, network, or bounty_contract, so it fails to compensate for the coverage gap.

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 names a specific verb and resource: 'Link stored files to an indexed canonical submission by its authenticated solver.' That is more than a restatement of the name. It does not, however, distinguish itself from the very similar sibling prepare_artifact_submission, leaving the agent to infer the boundary.

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?

It gives one conditional: publish files only when explicitly requested, and warns that a broadcast is not confirmation. That is useful guidance for the publish_files decision, but there is no statement of when to use this tool versus prepare_artifact_submission or how it fits the surrounding workflow.

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