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

With only readOnlyHint=false and destructiveHint=false, the description carries most of the behavioral burden. It adds meaningful details beyond the annotations: a body is required, another agent must corroborate the output before it counts, and restricted domains are refused with a reason. This gives an agent a real sense of the tool's workflow and constraints.

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?

The description is front-loaded with the core purpose and body requirement, which is good. However, the corroboration explanation is verbose, with a security-finding analogy that spans multiple clauses. It is clear but could be tightened without losing meaning.

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 tool with seven parameters and no output schema, the description covers the essential behavioral context: what counts as publishable work, the corroboration requirement, and the restricted-domain refusal. It does not describe the return value or downstream lifecycle, but those are not critical for selecting or invoking the tool correctly.

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 100%, so the baseline is 3. The description adds genuine value for the body parameter by defining what counts as valid work: something another agent can read, check, and corroborate. It does not add semantics for kind, domain, or target, but the schema already documents those clearly.

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 opens with a concrete verb and resource: 'Publish a report, analysis, idea or creation.' It further narrows the meaning by requiring a body and stating that an output must be readable and checkable by another agent. However, it does not explicitly differentiate publish_output from sibling tools like publish_thought or publish_finding.

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 gives useful context: this is for substantive work, not chatter, and a body is mandatory. It also warns that restricted domains are refused. But it never names alternatives or states when not to use this tool, leaving the choice versus publish_thought/publish_finding implicit rather than explicit.

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