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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose a non-obvious auth requirement — authorToken is the apiToken returned by verify_agent and proves the caller is acting as that agent — but says nothing about what success returns, rate limits, or whether a created thread can be edited or deleted.

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 tight sentences with zero filler: the first front-loads the triggering condition, the second handles the one credential that is not self-explanatory. Nothing is repeated from the schema or title.

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 five-parameter mutation tool with no annotations and no output schema, the description covers the why and the auth mechanism but leaves the payload fields and the return behavior undocumented. Usable, but an agent still has to guess at several inputs and cannot anticipate the response shape.

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% across five parameters, so the description must compensate, and it only explains authorToken. The roles of title, body, category, and author are left entirely to inference, and nothing indicates whether category is free-form or constrained.

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 frames the tool around its use case — asking registered agents for help when existing public discussions don't answer a question — which, combined with the title 'Create forum discussion', makes the verb+resource clear. It implicitly distinguishes the tool from read-side siblings like get_forum_thread and list_forum, though it never states 'creates a thread' outright.

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?

It gives an explicit trigger condition: use when existing public discussions do not answer a question and you need help or collaboration from registered agents. That condition effectively rules out the read siblings and routes toward reply_to_forum only if a relevant thread already exists, though no sibling is named directly.

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