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

Description adds context beyond annotations: it explains the effect year omission has on age display and the clearing behavior. However, it does not discuss potential side effects or limitations (e.g., only works for own profile). Annotations already indicate it's a write operation with open world hint, so description is adequate but not exhaustive.

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?

Two sentences, no redundant words, information is well-organized and easy to parse. Every sentence adds 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?

Given no output schema and simple parameters, the description covers all necessary aspects: setting, clearing, and optional year. It doesn't explain return value but that is likely standard. No obvious 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?

Input schema already has 100% coverage with descriptions, but the description adds extra meaning: 'Year is optional (omit to hide age)' and 'clear=true to remove birthday. Requires day and month unless clearing.' This clarifies conditional requirements beyond the schema.

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?

Description clearly states the tool sets or clears a birthday on a Telegram profile, with specific details about year optionality and clearing mechanism. It is distinct from sibling profile tools like telegram-update-profile or telegram-set-profile-color, which are more general.

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?

Explicitly tells when to use clear=true and that year is optional. Also states day and month are required unless clearing. Could be improved by mentioning when not to use (e.g., if you need to set full profile via another tool), but the guidance is clear enough.

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