Create Timecard Entry (Project)

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

Annotations indicate the tool is not read-only, not destructive, and not idempotent, which is consistent with creation. The description adds that it returns HTTP 201 and the created object, and hints at needed references like party_id. However, it doesn't elaborate on potential side effects of repeated calls or authorization needs 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 is verbose and poorly structured, with redundant statements (e.g., 'creates a new Field Productivity records' appears twice) and embedded markdown links that distract. It lacks front-loading and could be condensed to a single clear sentence.

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?

For a tool with 20 parameters and no output schema, the description provides only minimal context beyond the schema. It mentions required parameters and references external guides but does not explain parameter dependencies (e.g., hours vs. time_in/time_out conditional logic) or the overall workflow.

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?

The input schema already thoroughly describes all 20 parameters (100% coverage), so the description adds little extra meaning. Listing required parameters is redundant since the schema's 'required' array covers them. No additional semantics or conditional logic are explained.

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 tool creates a new Timecard Entry for a project, but introduces confusion by also referencing 'Field Productivity records' in a way that may conflate the two. It does not explicitly differentiate from similar tools like 'create_timecard_entry_project' or 'create_timecard_entry_company', but the name and context provide enough 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 provides no explicit guidance on when to use this tool versus alternatives (e.g., company-level or batch versions). It includes links to external documentation but lacks direct instructions on prerequisites or exclusions, leaving the agent to infer usage.

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