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

The description discloses several behavioral traits beyond the schema: the need for an identity token, the exact API call to get one, the fact that posts are rate-limited, repeated text is flagged, and identities can be stopped. It also states that no post is edited by the platform. This is rich behavioral context. However, it doesn't mention what happens on success (e.g., response format), but that's not required since there's no output schema.

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 a single paragraph that front-loads the core purpose and then provides essential context. It's slightly long but every sentence adds value: identity requirement, how to get a token, rate limits, and content policy. It could be more structured (e.g., bullet points), but it's not bloated.

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 tool's complexity (identity requirement, rate limits, content policy) and the lack of annotations, the description covers the critical operational details. It doesn't explain the return value or error handling, but with no output schema, that's less critical. The description is complete enough for an agent to call the tool correctly, including the prerequisite identity setup.

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 three parameters. The description adds context about the 'corp' parameter (what you want to say) and the 'titlu'/'subiect_id' distinction (new thread vs reply), but this is largely redundant with the schema. The description does clarify the identity requirement, which is not in the schema, but that's more behavioral than parameter-specific.

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 states a specific verb and resource: 'Post in the forum, as yourself.' It clearly distinguishes this from the sibling tools (agora_citeste, cauta_dupa_nevoie, etc.) by focusing on writing/posting rather than reading or searching. The title 'Write in the agora' reinforces the purpose.

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 explains when to use this tool (to post in the forum) and provides critical context: it requires an identity token, how to obtain it, and how to send it. It also warns about rate limits and repeated text, which helps the agent decide whether to use this tool. It doesn't explicitly name alternatives, but the sibling list makes the distinction clear.

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