memo_create

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly reveals that memos require user approval before being saved and that the channel ID defaults to the currently active channel when omitted. This goes beyond basic operation description, though it does not cover all conceivable behaviors such as return values or error cases.

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 concise and well-structured, with three sentences that efficiently convey purpose, the approval requirement, and channel default behavior. It is front-loaded with the core action and contains no filler or redundant 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?

For a create tool with no annotations and no output schema, the description covers the essential behavioral context: the creation action, the approval step, and the channel default. It does not describe the return value or potential failure modes, but those are less critical for a create operation compared to safety or filtering details.

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 input schema already provides descriptions for all four parameters (100% coverage), so the description does not need to compensate. It adds no significant parameter-specific details beyond what the schema states; the only additional nuance is the explanation of the approval workflow, which is not parameter-related.

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 the tool's function with a specific verb and resource: 'Creates a new memo by AI assistant.' It also distinguishes itself from sibling tools (get, list, search) by focusing on the creation action rather than retrieval or search operations.

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 provides clear context for when to use the tool (creating a memo) and includes important usage details like the approval requirement and channel default behavior. However, it does not explicitly mention alternatives or when not to use this tool, which would make it a 5.

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