channel_deleteChannel

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action and owner requirement, but does not explain that deletion is permanent, whether it affects subscribers, requires special permissions, or if it can be undone. This is a significant gap for a destructive 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 a single short sentence, which is concise and front-loaded. However, it under-specifies essential behavioral details, making it not appropriately sized for a tool with no annotations; the brevity comes at the cost of completeness.

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 tool is simple with 2 parameters and full schema coverage, so the description is mostly adequate for understanding what the tool does. Yet it omits important context such as the outcome for subscribers, irreversibility, and any ownership/permission requirements beyond the phrase 'you created'. This makes it incomplete for a deletion 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?

The schema descriptions cover both parameters (chatId and sessionId) completely with 100% coverage, so the description does not need to repeat them. However, the description adds no additional meaning beyond the schema, such as which parameter identifies the channel to delete, so it meets the baseline but no more.

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 uses a specific verb 'Delete' with a clear resource 'a channel you created'. It distinguishes itself from sibling tools by adding the ownership constraint 'you created', which clarifies its scope compared to other channel operations and chat_delete.

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 phrase 'you created' implies that this tool should only be used on channels owned by the caller, giving some usage context. However, it does not explicitly mention alternatives (e.g., chat_delete for regular chats) or exclusions, leaving usage guidance mostly implied.

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