Create Standard Cost Code

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

The description mentions successful creation returns HTTP 201, but it does not address error cases (e.g., duplicate codes), required authentication, or side effects. Annotations (readOnlyHint: false) confirm it's a write operation, so no contradiction.

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 four sentences with some repetition ('Creates a new Work Breakdown Structure records' appears twice). It includes the endpoint but could be more concise without losing key info.

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 output schema, the description mentions the return object, but lacks details on expected structure of the nested 'standard_cost_code' parameter, error responses, or pagination. Adequate but not 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 coverage is 100%, so baseline 3. The description lists required parameters but adds no semantic detail beyond the schema descriptions. For example, the 'standard_cost_code' object's structure is not 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 Standard Cost Code and links to Work Breakdown Structure records. However, it does not explicitly differentiate from siblings like 'create_standard_cost_code_list' or 'create_cost_code', which reduces 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?

It lists required parameters and the HTTP status, but provides no guidance on when to use this tool versus alternatives like 'create_standard_cost_code_list' (creating the list vs. a code) or prerequisites (e.g., the list must exist first).

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