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

No annotations are provided, so the description must fully convey behavioral traits. It discloses Ed25519 signing by the server, subscriber verification, token-based authentication, and the critical side-effect of broadcasting to every subscriber. This goes well beyond a simple 'publish' statement and gives the agent a strong understanding of consequences.

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 concise, with three sentences covering purpose, mechanism, and a warning. It is front-loaded with the main action and contains no filler or redundant information.

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?

Given the lack of an output schema and the complexity of the operation (7 parameters, nested objects, side effects), the description covers essential context: signing, authentication, broadcast, and owner confirmation. It does not detail response formats or error handling, but the core usage is sufficiently specified.

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 high (86%), and the input schema already provides meaningful descriptions for each parameter. The tool description does not add additional parameter-level semantics, so a baseline score of 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?

The description clearly states the tool's function: 'Publish a signed update to a feed.' This is specific with a verb and resource, and it distinguishes itself from sibling tools like create_feed and list_feeds. No ambiguity about what this tool does.

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 provides clear context for use, including that publishing broadcasts to all subscribers and requires a publisher or admin token. It also includes an important caution to confirm content with the feed owner before calling. However, it does not explicitly mention alternatives or when not to use this tool compared to siblings.

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