Update Checklist Item

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

Annotations indicate write operation (readOnlyHint=false) and non-destructive. The description adds that it performs a partial update (PATCH), returns the modified object, and includes API endpoint details. No contradiction with annotations.

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?

Moderately concise with four sentences, but contains redundancy (e.g., 'Updates Checklist Item' is restated). Structure is front-loaded with purpose, but includes unnecessary repetition of required parameters already in the schema.

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?

Covers the basic purpose, update behavior, and return value. However, with no output schema and nested objects (item, attachments), an agent may need more guidance on the structure of the 'item' object and the response format. Fills most gaps but leaves some.

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%, so baseline is 3. The description lists required parameters but adds no extra semantics beyond the schema. It does imply the 'item' object fields are partial, but this is more about behavior than parameter meaning.

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?

Explicitly states 'Updates Checklist Item in a specified Checklist' and references 'update an existing Inspections' (though with a typo). Distinguishes from siblings like update_checklist and update_checklist_section by the resource name. However, the confusing phrase 'Inspections' slightly undermines clarity.

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 basic usage guidance ('Use this to update an existing Inspections') and notes that only supplied fields are changed. Does not offer alternatives or when-not-to-use context, which would be helpful given the many sibling update tools.

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