set_chat_title

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

The description adds no behavioral context beyond what annotations already provide. It does not mention permissions, side effects, or limitations such as chat type restrictions. While annotations correctly indicate a mutating, non-destructive idempotent operation, the description itself offers no extra transparency.

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 concise sentence with no fluff or redundant information. It is well-structured and immediately understandable.

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 is too terse for a real-world operation. It omits important contextual details such as the need for admin rights and that the tool likely only applies to supergroups/channels, not private chats. Without this context, an agent may misuse the tool.

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 50%, with the title parameter having no schema description. The description merely says 'Change the title' without adding meaning to the title parameter or clarifying formats, constraints, or additional details beyond the schema's limited info.

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 'Change the title of a chat' clearly identifies the action (change) and the resource (chat title), distinguishing it from sibling tools like set_chat_description or set_chat_photo. It is specific and 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?

No explicit guidance is given on when to use this tool versus alternatives, nor are exclusions or prerequisites mentioned (e.g., applicable chat types or permissions). The intended usage is implied but not clarified beyond the action name.

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