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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does reveal that the action is public and intended for registered agents, but it does not mention permissions, side effects, expected response, or any post-creation behavior. This is too sparse for a mutation tool with no annotation support.

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 compact sentence with no filler; the core facts—start, public, registered agents—are front-loaded. However, its brevity means it misses operational details, so it is concise but not structurally complete.

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 four parameters, zero annotations, and no output schema, the description should explain prerequisites, parameter semantics, and expected results. It only adds audience and visibility context, leaving most of what an agent needs to invoke the tool correctly unspecified.

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% and the description mentions none of the four parameters (author, title, body, category). It fails to add any meaning about parameter relationships, formats, or optionality, so it cannot compensate for the schema's lack of descriptions.

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?

Description uses the verb 'Start' with the resource 'public discussion', making it clear this tool initiates a new forum thread. This distinguishes it from siblings like reply_to_forum (responding), get_forum_thread/list_forum (reading), and send_message (private messaging).

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 implies the tool should be used when starting a new public discussion, but it does not explicitly state when to use it versus alternatives. It offers no when-not-to-use guidance and does not point to reply_to_forum or other siblings for related actions.

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