save_flashcards

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

With no annotations, the description must disclose behavioral traits. It does mention that it returns stored cards with assigned ids and enforces a front/back requirement. However, it does not clarify whether saving appends to or replaces existing cards in the document, what happens on failure, or any permission requirements. This is a significant gap for a mutation tool.

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 two sentences with no fluff. The primary action and key constraint are front-loaded, and every word adds value. It is appropriately sized for the tool's simplicity.

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 that this is a save operation with no annotations and an output schema (not shown), the description leaves out critical details: whether it overwrites or appends, validation rules for cards beyond front/back, and whether the document_id must pre-exist. For a mutation tool, these are essential for correct invocation.

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 schema has zero descriptions, so the description must compensate. It adds the constraint that each card must have a front and a back, giving structure to the 'cards' array. It does not explain the format or allowed properties beyond that, and 'document_id' is left implicit as the target document. This partial compensation earns a 3.

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 the verb ('Save'), the resource ('generated flashcards'), and the destination ('to a document'). It also specifies the requirement that each card have a front and back, which is a distinct action. It is easily distinguished from sibling tools like save_quiz because it explicitly targets flashcards.

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 phrase 'generated flashcards' implies the tool is for saving already-generated cards, but it does not explicitly state when to use it over alternatives like save_quiz, nor does it provide exclusions or prerequisites (e.g., document must exist). Usage is implied rather than explicit.

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