Update Timecard Entries

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

Annotations already provide readOnly=false, destructive=false. Description adds 'only supplied fields changed' (partial update) and 'returns modified object'. However, it does not disclose permissions, side effects, or the relationship between timecard entries and the timesheet endpoint. Potential confusion between 'Field Productivity records' and timesheets.

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?

Two effective sentences plus API metadata. Front-loaded with action. No unnecessary fluff. Minor redundancy in repeating 'Field Productivity records' and endpoint details.

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?

Lacks explanation of the relationship to timesheet_id and when it's needed. No output schema, so minimal return value description. Sibling tools exist but not contextualized. Adequate for a simple update but missing some context.

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%, so baseline 3. Description adds 'Required parameters: project_id, timecard_entries' but does not explain the optional timesheet_id or the structure of the timecard_entries array. The endpoint path suggests timesheet might be a resource, but usage is unclear.

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?

Clearly states it updates timecard entries with specific verb and resource. Mentions 'only the supplied fields are changed' but first sentence says 'Update the date', causing slight ambiguity. Does not differentiate from siblings like bulk_update_timecard_entries or edit_a_timecard_entry.

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?

Implied usage for updating existing Field Productivity records. Lists required parameters but does not explicitly state when to use this vs. alternatives (e.g., bulk update or single entry update). No exclusions or prerequisite conditions.

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