getChatAdministrators

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

No annotations are present, so the description must carry behavioral context. It discloses that bot administrators are excluded and that the return value is an Array of ChatMember objects. It does not mention potential error cases, chat-type restrictions, or any authorization requirements, but for a simple read-only getter this is a reasonable minimal disclosure.

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 concise sentences with no filler. It front-loads the core action and resource, then gives the return type. Every word contributes useful information.

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?

This is a low-complexity tool with one required parameter, no nested objects, and no output schema. The description includes the return type and a key behavioral filter, which together cover the essential information needed to call it correctly. It could note permission or failure conditions, but those are not critical for this simple getter.

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?

The schema description for chat_id is already complete and explains the integer or string formats including the @channelusername form. The tool description adds no new parameter-level detail, but with 100% schema coverage the baseline 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 clearly states a specific verb and resource: 'Get a list of administrators in a chat'. It adds a useful distinguishing detail by excluding bots and names the return type, Array of ChatMember objects. This is enough to tell the tool apart from sibling chat-related tools like getChat or getChatMemberCount.

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 intended usage is implied by the description: use this when you need the chat administration list. However, it does not explicitly compare against alternatives such as getChatMember for a single member or getChatMemberCount for a count, so the agent must infer the choice from the name and description alone.

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