edit_message_checklist

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

Annotations indicate a mutating, idempotent, and non-destructive operation, but the description adds no behavioral context beyond that. It fails to disclose what editing a checklist entails, side effects, or whether the checklist parameter replaces the entire message.

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, but it is under-specified. The version suffix '(v9.1)' adds no value and could be considered noise, while the core sentence is too terse to be genuinely helpful.

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?

Given four parameters, no output schema, and the concept of a 'checklist' that is likely specific to this API, the description omits critical details such as how the checklist is updated, whether partial edits are supported, and what the response contains.

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 only 25% (only chat_id is described). The description does not explain the 'checklist' or 'reply_markup' parameters, nor does it clarify which parameters are needed for editing. It adds no meaning beyond the tool name.

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?

Purpose is clear: 'Edit a checklist message' uses a specific verb and resource type, distinguishing it from generic edit_message_text or edit_message_caption. However, the version suffix '(v9.1)' is unnecessary and slightly undermines clarity.

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 guidance on when to use this tool versus alternatives like edit_message_text or send_checklist. No prerequisites, exclusions, or context provided.

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