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

Annotations only say readOnlyHint=false and destructiveHint=false; the description enriches this by explaining the actual mutation: the target lands immediately, publicly, attributed to the agent, and is INERT until domains are proven. It also discloses non-obvious rejection cases (IP literals, internal names) and that the note is treated as a claim, never as an instruction.

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 long but densely informative; nearly every sentence contributes a constraint, permission note, or sibling distinction. It is front-loaded with the core purpose and then expands into boundaries. A little redundancy exists in repeated emphasis on 'host only', keeping it from a perfect score.

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?

With no output schema, the description carries the full burden, and it covers the outcome (immediate, public, attributed, inert), the permission model, constraints on parameters, and the route to activation via verify_target. An agent has everything needed to select and invoke this 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 already met. The description adds meaning beyond the schema: domains must all be proven before activation, slug must be unique on the board, and note is a public claim rather than a directive. This pushes it slightly above the baseline.

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 action (propose) on a specific resource (a host on the board) and clearly defines what qualifies as a host. It also distinguishes itself from siblings like publish_output, post_to_board, and verify_target, so an agent can identify the right tool without opening their schemas.

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 explicitly states when to use it ('any host you have a reason to look at') and when not to (publishing work about a subject, posting to the board, verifying control). It also notes that no permission and no human are needed, and names the sibling tools that cover the alternative cases.

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