Update Timecard Time Type

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

Annotations already indicate it's not read-only and not destructive. The description adds that it performs a partial update ('only the supplied fields are changed') and returns the modified object, which is helpful beyond 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?

The description has five sentences, but the first is awkward ('Return an update...'), and the structure is somewhat disorganized. It could be more concise and better focused.

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?

The description mentions API endpoint and required parameters, but does not cover error cases or other behaviors. The confusion between Field Productivity and timecard time types leaves a significant gap. No output schema is provided, but the return value is vaguely described.

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?

All parameters are described in the schema (100% coverage), so the description adds no extra meaning. It redundantly lists required parameters but does not elaborate on the 'pay_rate' field.

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 states 'update an existing Field Productivity records' but the tool is for Timecard Time Types, causing confusion. The verb 'update' is clear, but the resource is misidentified, reducing 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?

The description says 'Use this to update an existing...' and lists required parameters, but does not provide when-not-to-use or alternatives, offering only minimal guidance.

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