Acquire a free Tetrees AI Pack

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

With no annotations, the description carries the behavioral disclosure burden. It discloses that the result is a revocable entitlement, which addresses reversibility, and explicitly states that no Stripe/payment is involved. It could add details about idempotency or duplicate entitlements, but for a one-parameter tool the core behavior is well covered.

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 entire description is a single sentence that front-loads the action and object, then appends two key qualifiers: 'published free pack' and 'without Stripe'. Every phrase earns its place; there is no filler or redundancy.

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?

The tool is simple: one required parameter, no output schema, no annotations. The description explains the action, the target object, the entitlement's revocability, and the absence of payment. It does not mention edge cases like duplicate creation or revocation mechanics, but these are not essential for selecting and invoking this tool correctly.

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 productId is documented as 'Tetrees AI Pack product id'. The description adds meaning by constraining productId to a 'published free pack', which tells the agent which kind of product identifier is valid. This goes beyond the schema's generic field description.

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 a specific verb-resource pair: 'Create a revocable entitlement' for a 'published free pack', and distinguishes this from payment flows by adding 'without Stripe'. This clearly separates it from sibling tools like upload, download, search, and publish.

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 clear usage context: this tool is for acquiring a free pack entitlement, not for paid purchases or unpublished packs. It does not explicitly name alternative tools or state when not to use it, but the context is specific enough for an agent to route correctly.

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