update_department

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

With no annotations, the description carries the full behavioral burden and does not meet it: it never explains that sync_token implements optimistic concurrency, what happens on a stale token (conflict/rejection), whether omitted fields like name or active are preserved or cleared, or whether changes are reversible. For a mutation tool with zero annotation coverage this is a substantial gap.

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?

A single front-loaded sentence with zero filler or redundancy. It is efficient, though the brevity reflects under-specification rather than disciplined editing.

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 nested params object does carry per-field descriptions (ID, name, active, sync token), and there is no output schema to explain, which limits how much the description must cover. However, for a mutation tool with no annotations and a concurrency token, the absence of any behavioral or precondition detail leaves the definition incomplete.

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 description adds no meaning beyond the schema; it never mentions that id and sync_token are both mandatory or that sync_token must come from a prior read. Schema description coverage is reported at 0%, so the description was expected to compensate and does not, leaving the concurrency parameter's semantics unexplained.

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?

States a specific verb and resource ('Update an existing department') scoped to QuickBooks Online, which distinguishes it from siblings like update_class, update_term, or create_department. It stops short of explicitly contrasting with update_class/update_term, but the resource name is unambiguous.

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?

There is no guidance on when to use this versus get_department, create_department, or search_departments, and no mention of prerequisites such as fetching the current sync_token before calling. Usage is only inferable from the verb 'Update'.

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