Behavior1/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Create', implying mutation, but gives no details about file reads/writes, side effects, permissions, or error handling. The mention of 'JSON file payload' does not clarify what the tool does with the input file or the optional output_file parameter. This is a significant gap for a tool that likely mutates the Anki collection.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is concise but under-specified. It is not a case of efficient brevity; critical information is missing. The description does not earn its place because it fails to convey any actionable context beyond the name's obvious intent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given this is a mutation tool with no annotations, an output schema (not visible), and three parameters with zero schema coverage, the description is vastly incomplete. It does not explain the input file format, the meaning of the output file, the deck name default behavior, or any expected results. An agent cannot correctly invoke this tool without external knowledge about Cloze note creation and the file payload structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must explain the parameters. It does not mention deck_name, input_file, or output_file at all, except indirectly via 'JSON file payload', which only hints at input_file. The required parameter input_file is undefined, and the optional deck_name and output_file have no meaning provided. The description fails to compensate for the schema's lack of parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Create') and resource ('Cloze deletion flashcard'), and hints at the input mechanism ('from a JSON file payload'). This distinguishes it from the generic add_note sibling, though it doesn't explicitly compare. It is reasonably clear what the tool accomplishes, but lacks details about the flashcard structure.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus the sibling add_note, nor any conditions or prerequisites. The description solely states what it does, not when it should be chosen. An agent has no basis to decide between this and other note-creation tools.

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