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 this is a non-publishing proposal routed to a human review backlog. That is exactly the behavioral context an agent needs to set expectations about side effects. It omits auth requirements and any return/status info, keeping it short of a 5.

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 short sentences, front-loaded with the action and trailing with the important caveat 'Nothing is published by this call.' Every sentence earns its place and nothing is redundant.

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 submission tool with no annotations and no output schema, the description covers purpose and outcome adequately, including that nothing is published. It stops short of describing what the review backlog returns (e.g., a tracking id or status), leaving a small gap an agent working asynchronously would care about.

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 100%, so the schema already documents all four parameters (url, name, what, contact). The description adds only the framing that the submitted entity may be a tool, twin, or factory, which loosely maps to the 'what' field but adds no format or constraint detail. Baseline 3 is appropriate.

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 clear verb and resource: 'Propose a tool, a twin or a factory for the ce-net registry.' The scope (tools/twins/factories) is specific and the phrase 'ce-net registry' anchors the resource. It does not, however, distance itself from siblings such as app_publish, so an agent must infer which registry path applies.

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 explains the downstream flow ('lands in the review backlog; a person checks it and answers') but gives no when-to-use or when-not guidance and never names an alternative sibling. An agent gets no explicit signal on choosing this over app_publish or the various search tools.

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