Behavior3/5

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

Annotations indicate this is not read-only and not destructive, which the description doesn't contradict. The description adds minimal behavioral context by mentioning the two input formats (file_id or URL) and acceptable file types (.webp/.tgs/.webm), but doesn't cover important aspects like authentication requirements, rate limits, error conditions, or what happens when sending fails.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with just one sentence that states the core functionality. While efficient, it might be too brief given the lack of other contextual information about this mutation tool. Every word earns its place, but more information would be helpful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no destructive hint but also no read-only hint, the description provides basic functionality but lacks important context. While an output schema exists (which reduces the need to describe return values), the description doesn't address prerequisites, error handling, or how this integrates with the broader Telegram API ecosystem represented by the many sibling tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description doesn't add meaningful parameter information beyond what's already implied by the tool name. It mentions 'file_id or URL' which relates to the 'sticker' parameter, but doesn't explain 'chat_id' or provide any additional context about parameter usage, format requirements, or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('send sticker') and target ('Telegram chat'), making the purpose immediately understandable. However, it doesn't differentiate this tool from other Telegram send tools like 'telegram_send_photo' or 'telegram_send_message' beyond the media type, which prevents a perfect score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives. The description mentions 'file_id or URL' but doesn't explain when one format is preferred over the other or how this compares to sending other media types like photos or videos through sibling tools.

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