Create Timecard Entry (Company)

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

Annotations already indicate this is a write operation (readOnlyHint=false) and not idempotent (idempotentHint=false). The description adds that it returns the created object on success (HTTP 201) but does not disclose any side effects, required permissions, or behavior beyond creation. 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?

The description is verbose, includes a markdown link, and contains a redundant phrase ('Creates a new Field Productivity records'). The first sentence is effective, but the overall length could be reduced without losing essential information. It is adequately structured but not optimally concise.

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 complexity of a flexible 'timecard_entry' object and no output schema, the description provides endpoint and domain context (Project Management > Field Productivity) and return status (HTTP 201). However, it does not explain the expected structure of the timecard_entry object or what the response contains, leaving gaps for an AI agent.

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?

Input schema already provides full coverage and descriptions for all three parameters. The description repeats some schema details (e.g., URL path vs request body) and references a guide for getting a party_id, which adds minor context. With 100% schema coverage, the baseline is 3, and no significant additional meaning is provided.

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 specifies it's at the company level, which helps distinguish from project-level siblings. However, it confusingly references 'Field Productivity records' as an alternative term, which may blur the purpose. Overall, the core action is clear.

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?

No explicit guidance is provided on when to use this tool versus alternative timecard entry tools (e.g., project-level, bulk creation). The description only mentions a guide for obtaining a party_id, which is not a usage guideline. Lacks when-to-use or when-not-to-use context.

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