sync_blocks_create

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'create,' implying a mutation, but gives no details on permissions, side effects, idempotency, or response behavior. This is a significant gap for a write operation.

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 extremely short, containing no wasted words, but it is under-specified. It provides a clear verb-object pair but omits any context or caveats. This is efficient yet minimal, bordering on insufficient.

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 tool has 2 parameters, no output schema, and no annotations. The description does not explain what sync blocks are, the relationship between ids and documentId, or the expected outcome. This is inadequate for a create operation in a domain with many sibling tools.

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 covers 100% of parameters (ids and documentId each have descriptions), so the baseline is 3. The description itself adds no parameter-level meaning, but the schema already documents the fields adequately.

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 'Create sync blocks' clearly states the action (create) and the resource (sync blocks). It is not a tautology and distinguishes the tool from non-sync-block siblings, though it does not differentiate it from sync_blocks_delete or sync_blocks_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 provides no guidance on when to use this tool versus alternatives like sync_blocks_delete or sync_blocks_list. There is no mention of prerequisites, context, or exclusions, so the agent is left without decision support.

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