Create Timecard Entry

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

Annotations already indicate readOnlyHint=false (write operation) and openWorldHint=true. The description adds only that it returns the created object on success (HTTP 201) and mentions the endpoint. No additional behavioral context such as side effects, authorization, or rate limits is provided beyond what annotations offer.

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 somewhat disjointed, mixing a link, API details, and required parameters. It is not overly long but could be more streamlined. The first sentence is direct, but the rest is less organized.

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 has 2 parameters with one being an open object and no output schema, the description provides the HTTP method, endpoint, and a reference for a prerequisite field. However, it lacks details on the expected shape of timecard_entry and differentiation from sibling tools. It is adequate but not thorough.

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% with descriptions for both parameters. The description adds a hint about using the Project People guide to get party_id, which may be part of the timecard_entry object. However, it does not explain the structure of the open object (timecard_entry) beyond the hint, so it meets the baseline but adds limited value.

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 new Timecard Entry' and mentions it creates 'Field Productivity records'. It specifies required parameters and the HTTP endpoint. However, it does not differentiate from sibling tools like create_timecard_entry_company or create_timecard_entry_project, relying on the version number in the name.

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 lists required parameters and references a guide for getting a contact's party_id, which hints at a prerequisite. But it provides no guidance on when to use this tool versus other timecard entry creation tools (bulk, company, project), nor any exclusions or alternatives.

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