createForumTopic

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

With no annotations provided, the description carries the behavioral disclosure burden. It discloses the required administrator permission and the return type (ForumTopic object), adding meaningful context beyond the schema. It doesn't describe failure modes, but the permission requirement is the key behavioral constraint for this creation operation.

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 two sentences with no filler. It front-loads the action and target, then follows with the permission requirement and return type. Every clause earns its place.

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?

The description covers the essential operational context: target resource, required permission, and return value. The schema covers all parameter details, so nothing critical is missing. A slightly richer note about the returned ForumTopic object's relevance or failure behavior would push it to fully complete, but it is sufficient for correct invocation.

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 input schema already documents all four parameters including icon color values and emoji identifier usage. The description adds no additional parameter-level semantics, so the 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 states a specific action ('Create'), a specific resource ('a topic in a forum supergroup chat'), and is distinct from sibling tools like editForumTopic or deleteForumTopic. The verb+resource combination makes the tool's purpose unambiguous.

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 clearly identifies when the tool applies (creating a topic in a forum supergroup chat) and gives a concrete prerequisite (bot must be an administrator with can_manage_topics rights). It doesn't explicitly contrast with alternatives, but the creation context is clear enough that an agent can select it over edit/close/delete siblings.

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