Sync Company Insurances (Alternative)

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

The description correctly indicates the tool creates or updates (matching readOnlyHint=false) and returns the modified object. However, it inconsistently refers to 'Directory records' while the tool is named for Company Insurances. Annotations provide no destructive or idempotent hints, and the description doesn't elaborate on potential side effects or prerequisites beyond Company ID.

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 about four sentences long but mixes concepts ('Company Insurances' vs 'Directory records') and includes redundant phrases like 'Updates the specified Directory records.' It could be more streamlined and consistent. Front-loading is acceptable with the first sentence stating the core function.

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 a sibling with a similar name (sync_company_insurances) and no output schema, the description should clarify the difference and return value expectations. It mentions 'returns the modified object' but the Company ID requirement is unexplained. The description fails to provide a complete picture for an agent to confidently invoke the tool.

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 has one parameter 'updates' with a generic description. The tool description mentions 'required parameters: updates' but adds no structural details about the array items. The claim 'Must provide Company ID in the request body' is not backed by the schema, causing confusion. Schema coverage is 100% but the main description adds very little meaningful semantic 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 states it 'creates or updates a batch of Company Insurances,' which clearly identifies the action and resource. However, it conflates 'Company Insurances' with 'Directory records' later, causing some ambiguity. The tool name includes 'Alternative,' but the description doesn't differentiate it from the sibling 'sync_company_insurances,' slightly reducing 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 says to 'use this to update an existing Directory records (only the supplied fields are changed)' and mentions the required parameter 'updates.' It also states 'Must provide Company ID in the request body,' but this isn't reflected in the schema. No guidance is given on when to use this tool vs. the regular 'sync_company_insurances' or other sync tools.

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