Copy From Standard Cost Code List

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

Annotations show readOnlyHint=false and destructiveHint=false, so the description must add behavioral context. It states that the tool creates a new record and returns HTTP 201 with the new object, but does not disclose side effects, auth requirements, or error conditions. This adds some value beyond annotations but is not comprehensive.

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 concise at 4 sentences. The first sentence states the purpose, followed by usage, outcome, required parameters, and API endpoint. It is front-loaded and every sentence adds value, though the API info could be considered extraneous.

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 moderate complexity and no output schema, the description covers the copy action, required parameters, and expected response (HTTP 201 with new object). It does not address error handling or edge cases, but is sufficiently complete for an agent to invoke the tool correctly.

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?

Input schema has 100% description coverage, setting a baseline of 3. The description explicitly lists two required parameters ('project_id, standard_cost_code_list_id'), which reinforces the schema but adds no new semantic information. It omits mentioning the optional 'sub_job_id' parameter.

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 'Copy Cost Codes from Standard Cost Code List' and explains it duplicates Work Breakdown Structure records as a new record. The verb 'copy' and resource are specific, but it does not explicitly distinguish from the sibling 'copy_subset_from_standard_cost_code_list'.

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 'Use this to duplicate' but provides no guidance on when to use this tool vs alternatives, such as the sibling 'copy_subset_from_standard_cost_code_list'. There are no when-not or alternative instructions.

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