Sync Standard Cost Codes

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

Annotations already provide readOnlyHint=false, destructiveHint=false, idempotentHint=false. The description adds value by specifying it is a batch sync using PATCH, that only supplied fields are changed, and that it returns the modified object. This goes beyond the binary hints, though more detail on creation logic would be helpful.

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 three sentences plus endpoint info. It is front-loaded with the primary purpose and efficiently conveys the necessary information without waste.

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's complexity (batch sync, multiple parameters), the description covers the main purpose and required parameters but lacks details on return value format, error handling, or partial failure behavior. With no output schema, more specificity about the response would improve completeness.

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 baseline is 3. The description only reiterates required parameters from the schema without adding extra semantic meaning or usage hints, so no additional value beyond baseline.

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 or updates a batch of Standard Cost Codes, using specific verbs and resource. It distinguishes itself from individual create/update tools by indicating it is a batch sync operation, and the context of Work Breakdown Structure is mentioned.

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 hints at when to use this tool ('Use this to update an existing Work Breakdown Structure records') but does not explicitly contrast with alternatives like create_standard_cost_code or update_standard_cost_code, nor does it provide exclusions. The guidance is adequate but lacks actionable nuance.

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