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

Annotations indicate this is a non-read-only, non-destructive, closed-world operation, but the description adds minimal behavioral context. It implies a mutation (removal) without specifying effects like whether the removal is permanent, if indices shift after removal, or any error conditions. The description doesn't contradict annotations but adds little beyond them.

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, direct sentence with no wasted words, making it easy to parse. It front-loads the core action and target efficiently, though this brevity contributes to gaps in other dimensions.

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 the tool's moderate complexity (mutation with 2 parameters), lack of schema descriptions, and presence of an output schema (which handles return values), the description is incomplete. It covers the basic purpose but misses key details like parameter meanings, usage context, and behavioral nuances, relying too heavily on the output schema and annotations.

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?

With 0% schema description coverage for 2 parameters, the description fails to compensate by explaining 'id' (e.g., note ID, checklist ID) or 'index' (e.g., zero-based position). It only mentions 'index' generically, leaving both parameters semantically unclear beyond their basic types in the schema.

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 ('Remove') and target ('checklist item by index'), which is specific and actionable. However, it doesn't differentiate from sibling tools like 'notes.toggle_checklist' or 'notes.delete' that might also modify checklists or notes, leaving some ambiguity about when to choose this specific removal method.

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 no guidance on when to use this tool versus alternatives like 'notes.toggle_checklist' or 'notes.update'. It lacks context about prerequisites (e.g., needing an existing checklist), exclusions, or typical scenarios for index-based removal, leaving the agent to infer usage from the tool name alone.

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