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

The description adds valuable behavioral detail beyond the annotations: it states the tool publishes to the learner's app, returns a deep link, and specifically discloses that the notes field is never shown to the learner. This gives the agent solid expectations for side effects and privacy, complementing the readOnlyHint=false and destructiveHint=false annotations.

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?

Three sentences with no redundancy: it states the action, the return, then two pieces of practical guidance. Information is front-loaded (action first), and each sentence earns its place without fluff.

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?

For a 10-parameter creation tool with a rich schema and output schema present, the description covers the core purpose, return behavior, best-practice usage, and a privacy nuance. Nothing essential is missing for an agent to invoke it correctly; the schema handles parameter details.

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 coverage is 100% and every parameter has a description. The description does not introduce new parameter meaning beyond restating the notes privacy and the card-count advice already present in the schema. It adds no new semantics that the schema doesn't already provide, so the baseline 3 is appropriate.

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 action ('Build a flashcard set and publish it') and the resource (flashcard set in Vocabit). It also mentions the return value (deep link), distinguishing it from list/get/update/delete siblings. The verb is specific and the purpose 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?

The description provides strong best-practice context ('Prefer one focused topic and 8-15 cards per set') but does not explicitly contrast with alternatives like update_study_set or when not to use it. It gives clear context for using the tool effectively but lacks an explicit 'use X instead' routing.

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