gift_premium_subscription

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

Annotations indicate a mutating, non-idempotent operation, but the description adds no behavioral context such as star deduction, recipient notification, or reversibility. It merely restates the action without disclosing side effects.

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 concise sentence with no fluff, but it skips important details. It is efficient in length but not in informational value.

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?

With three required parameters, sparse schema descriptions, no output schema, and no behavior details, this description is far from complete for a mutating gifting action. It leaves critical gaps.

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 description coverage is only 33%, and the description does not explain any parameters. month_count and star_count are completely undescribed, leaving the agent to guess their meaning and relationship.

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 'Gift' and a specific resource 'Telegram Premium subscription', clearly distinguishing this from sibling tools like send_gift which handles regular gifts. The purpose is unambiguous even though terse.

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 for gifting a Premium subscription but provides no explicit guidance on when to use this vs alternatives like send_gift or edit_user_star_subscription. No exclusions or alternatives are mentioned.

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