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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It reveals that cards are 're-materialized' and 'each lives once', which hints at uniqueness/idempotency, but it omits details about side effects, required permissions, or the role of verify_signature.

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 a single, compact sentence with no wasted words. It front-loads the primary action and resource, earning full marks for efficiency.

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 tool with 3 parameters, no annotations, and no output schema, a one-line description is insufficient. Critical information about parameter semantics, behavioral effects beyond card duplication, and usage context is lacking.

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 0%, and the description only explains the bundle parameter ('exported study bundle'). The 'key' and 'verify_signature' parameters are left entirely undocumented, so the description fails to compensate for the missing schema descriptions.

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 uses the specific verb 'Import' with the resource 'exported study bundle', and the phrase 're-materializes its cards' clarifies the effect, distinguishing it from study_export (the inverse) and study_create (which likely creates fresh studies).

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 implies usage when a study bundle exported via study_export needs to be restored, but it does not explicitly state when to use this over alternatives or any exclusionary conditions. It lacks explicit guidance on when not to use it.

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