set_note

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

No annotations are provided, so the description alone must convey behavioral traits. It simply says 'Store a note' without disclosing whether it overwrites existing notes, requires permissions, or has side effects. This is insufficient for a write operation, leaving key behaviors ambiguous.

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 with no redundancy, achieving high conciseness. However, it lacks any structural elements like examples or clarifications, which slightly reduces its effectiveness, though it remains appropriately brief for a simple tool.

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 no output schema and no annotation context, the description should provide more operational details such as return value or overwrite behavior. It only states the basic action, which is incomplete for a note-storing tool, especially given the presence of related sibling tools that could be cross-referenced.

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 has 100% coverage, with both 'key' and 'value' clearly described. The description adds no additional meaning beyond the schema, but since the schema fully documents the parameters, a baseline score of 3 is appropriate.

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 action ('Store') and the object ('a note') in a specific location ('in the scratchpad'). This distinguishes it from sibling tools like get_note, list_notes, and delete_note, which perform different operations on notes.

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 implies the tool is for storing notes and provides the context of a scratchpad, but it does not explicitly mention when to use this tool versus alternatives like get_note or delete_note. The usage is clear but lacks any exclusionary or comparative guidance.

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