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

With no annotations provided, the description carries the full burden. It discloses a key behavioral trait: 'Only one entry per employee/date/activity/project combo', which indicates uniqueness constraints and potential error conditions. However, it doesn't mention other important aspects like authentication needs, rate limits, or what happens on duplicate attempts, leaving some gaps in transparency.

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 extremely concise with just two sentences that are front-loaded with the core purpose. Every word earns its place, with no wasted text, making it easy for an AI agent to parse quickly and understand the essential information.

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 no annotations and no output schema, the description provides basic purpose and a constraint, but it lacks details on error handling, response format, or prerequisites. For a creation tool with 6 parameters, this is adequate but has clear gaps, making it minimally viable rather than fully complete.

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 description coverage is 100%, so the schema already documents all 6 parameters thoroughly. The description doesn't add any meaning beyond the schema, such as explaining parameter relationships or constraints beyond the uniqueness rule mentioned. This meets the baseline of 3 since the schema does the heavy lifting.

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 specific action ('Create a new timesheet entry') and the resource ('log hours'), distinguishing it from sibling tools like 'update_timesheet_entry' or 'delete_timesheet_entry' by specifying it's for creation only. The phrase 'Only one entry per employee/date/activity/project combo' adds unique behavioral context that further differentiates it.

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 implies usage context by stating 'Only one entry per employee/date/activity/project combo', which suggests when to use it (for creating new entries) and hints at constraints, but it doesn't explicitly mention when NOT to use it or name alternatives like 'update_timesheet_entry' for modifications. This provides some guidance but lacks explicit comparison to siblings.

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