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

Annotations are absent, so the description must carry behavioral disclosure. It does reveal a cost aspect ('Paid via x402'), which is useful, but it does not state whether the operation is read-only, what side effects (if any) exist, or any rate limits. The 'status' wording implies a read operation but never explicitly confirms it.

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 extremely concise—two short sentences—and both carry information: the first identifies the subject, the second notes the payment method. It is front-loaded and free of fluff. It sacrifices some completeness for brevity, but as a standalone text it is efficiently structured.

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?

Despite being a simple tool with no parameters, the description omits any information about the return value or output format. 'Status' is vague—does it return a boolean, text, an object? Without an output schema, the agent cannot know what to do with the result. The payment detail is clear, but the core purpose and expected outcome remain under-specified.

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?

The tool has zero parameters and schema coverage is 100% (empty schema). The description adds no parameter details because none are needed; the baseline of 4 applies given the absence of parameters. No further semantic clarification is required.

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 names the resource ('Telegram bot integration status') which aligns with the tool name, but lacks an explicit verb like 'get' or 'check'. It is distinguishable from siblings (get_market_stats, get_onchain_sales) by subject, but the phrase is a noun phrase rather than a clear action statement, leaving some ambiguity about what the tool actually returns.

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?

No guidance is given about when to use this tool versus alternatives or what conditions might warrant it. There is no mention of prerequisites, typical scenarios, or exclusions. The description is purely declarative and offers no decision-making support.

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