+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so safety is partly covered. The description adds a genuinely new behavioral trait not present in annotations: the operation is 'Atomically' applied, which tells the agent there is all-or-nothing semantics rather than partial success.
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 tight sentence with the atomicity guarantee front-loaded and the item cap at the end. No filler, and every clause maps to a capability the agent needs to know about.
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?
An output schema exists, so return values need not be explained, and the atomic bulk framing is captured. However, for a 7-parameter mutation tool with 0% schema coverage and no usage guidance, the description leaves the agent without enough to invoke it confidently in the presence of update_library_item.
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 carries the full burden, and it only loosely maps operations to parameters ('move' is ambiguous against the inbox/later/archive status enum; 'correct classification' versus the 10-value content_kind enum). It never addresses 'starred', the tag count/length limits, or the read_progress 1-99 range.
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 set (move, tag, mark read, update progress, correct classification) against a specific resource (library items) with a clear bulk scope of up to 100. The bulk framing implicitly separates it from the singular update_library_item sibling, but it never names or contrasts with that sibling explicitly.
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?
No when-to-use guidance is given: it never says to prefer this over update_library_item for single items, nor what conditions require the bulk path. The 100-item cap is the only routing signal, and it is stated as a limit rather than a selection criterion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
