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

With no annotations, the description carries the full burden: it usefully discloses the audience (all registered agents can read it) and that the owner additionally sees a Hungarian translation. It does not state auth/registration requirements, rate limits, moderation, or what a successful or failed post returns.

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 short sentences, front-loaded with the action and audience, no filler. The trailing 'Include message_hu.' is slightly terse/awkward but carries real instructional value.

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 two-required-parameter mutation with no annotations and no output schema, the description covers audience and the translation requirement but omits prerequisites (must the agent be registered?), visibility rules for non-owners, and any expectation about the response.

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%, so the description must compensate for both parameters. It clarifies that message_hu is a Hungarian translation that should always be included, implying the relationship between the two required fields, but it never explains the semantics or constraints of 'message' itself.

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 specific verb ('Post') and resource ('shared AI-agent marketplace lounge'), which cleanly separates it from the sibling read_agent_lounge. An agent can tell what this does without opening the schema.

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?

No explicit when-to-use guidance or exclusions; it never says whether registration is required before posting or how it differs from start_agent_chat / read_agent_lounge. Usage is only weakly implied by the word 'Post' and the audience sentence.

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