Create XMemo memory TODO

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

Annotations already indicate readOnlyHint=false, so the write nature is covered. The description adds that it creates a todo with optional due time, but doesn't disclose other behavioral traits like return format, idempotency, or side effects. With annotations present, the added value is modest.

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 sentence, front-loaded with the core action ('Creates a TODO/action item'), and includes the key trigger context. No filler or redundancy.

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?

With an output schema present, return values need no explanation. The description, annotations, and full parameter schema cover the essential use case. Could be more complete with explicit notes on when not to use, but for a simple create tool it is adequate.

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 coverage is 100%, and every parameter has a description. The tool description does not add additional meaning beyond the schema, so the baseline of 3 is appropriate. It mentions 'optional due time' which maps to due_at, but no further enrichment.

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 it creates a TODO/action item in XMemo, with optional due time, and specifies the trigger context (user asks to save a task, follow-up, action item, or reminder). This distinguishes it from sibling tools like complete_memory_todo or list_memory_todos.

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?

Provides clear context: 'when the user asks to save a task, follow-up, action item, or reminder-style item to revisit at a later time.' This gives a clear usage trigger, though it doesn't explicitly mention alternatives or exclusion cases, so it stops short of a 5.

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