Sync Projects

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

Despite annotations covering read-only/destructive hints (which are both negative), the description adds substantial behavioral context: partial update semantics ('Send only the fields you intend to change; omitted fields keep their current values'), return behavior ('Returns the modified project on success'), and common error statuses (401, 403, 404). This goes well beyond the structured annotations.

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 well-structured with clear sections for purpose, documentation links, code constraints, recommendation, and response/error behavior. Every sentence adds value, and the first line delivers the core action immediately. It is appropriately sized for a batch sync operation.

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?

The description covers operational essentials like partial updates, return values, and error codes, and points to documentation for sync actions. However, the `updates` array item structure is left open in the schema and the description only hints at fields like country_code, so an agent would need the linked documentation for full field-level guidance. Still, the core invocation requirements are covered.

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 schema already provides 100% description coverage for the three top-level parameters, so the baseline is 3. The description enriches the `updates` array semantics by specifying that omitted fields retain current values and by mandating ISO-3166 Alpha-2 formatting for nested `country_code` and `state_code` parameters. This added guidance is valuable but not exhaustive, hence 4.

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 opens with 'Create or update a batch of projects,' which clearly states the verb, resource (projects), and batch scope. This distinguishes it from sync tools for other resources like sync_sub_jobs or sync_tax_codes. The endpoint and API section further anchor its purpose.

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 'Recommendation' section explicitly warns against using the sync endpoint for bulk project creation due to performance bottlenecks, providing a clear when-not-to-use. It also advises to send only changed fields and mentions required parameters, giving context for use. However, it does not explicitly name alternative tools (e.g., create_project or update_project), so it falls short of a 5.

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