Create todo

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

Annotations already indicate the tool is not read-only (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds no behavioral context beyond 'Create', leaving the agent unaware of side effects, required authentication, or what happens to existing data. Since annotations are present, the bar is lower, but the description fails to add value.

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?

Two sentences, no wasted words. However, the second sentence is a technical note that may confuse rather than clarify. It is concise but could be more helpful by front-loading a clearer purpose instead of the handler detail.

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?

Despite high schema coverage, this is a creation tool with 8 parameters and no output schema. The description does not explain what happens after creation (e.g., return value, success indication, or side effects). The agent needs more context to understand the tool's behavior fully.

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 100%, so each parameter already has a description. The tool description adds no additional parameter-level meaning. Baseline score is 3, as the description does not compensate for any gaps.

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 'Create a lightweight todo', which identifies the verb (create) and resource (todo). However, it does not differentiate from sibling tools like 'memory_create_task', which likely creates a similar entity, missing an opportunity to clarify when to use this specific tool.

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. The description only states what it does, without any contextual hints about prerequisites, exclusions, or preferred scenarios. The mention of 'Same handler as memory(action="create_todo")' is a technical implementation detail, not usage guidance.

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