synchronize_account

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

With no annotations provided, the description carries the full burden. It discloses that Mail may continue syncing after the tool returns, which is a key behavioral trait. It also mentions the return type (summary). However, it does not detail side effects or authorization needs, but for a simple sync tool, this is adequate.

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 concise with two clear sections (Args and Returns). Every sentence serves a purpose, and the main action is front-loaded. No wasted words.

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 simplicity (one optional parameter) and the presence of an output schema (not shown but implied), the description adequately covers what the tool does and its return. It could mention error conditions or prerequisites, but the core functionality is well-explained.

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 0%, so the description must compensate. It explains the 'account' parameter: optional, when omitted all accounts are synced. This adds clear meaning beyond the schema's type and default, fully clarifying usage.

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 it asks Apple Mail to synchronize one or all accounts. It uses a specific verb ('synchronize') and resource ('account'), and among sibling tools, no other tool duplicates this purpose, so differentiation is clear.

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 explains when to use the tool (to synchronize accounts) and notes that omitting the account parameter syncs all accounts. It lacks explicit guidance on when not to use it or alternatives, but the context is clear enough for an AI agent.

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