telegram_config_status

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

There are no annotations, so the description carries the full burden of behavioral disclosure. The description only says 'check', which implies a read-only operation, but it does not disclose what happens if the configuration is invalid, whether errors are thrown, or what the output format is. This is insufficient for an agent to understand side effects or failure modes.

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 that directly states the tool's purpose. It is front-loaded and contains no filler. For a simple zero-parameter tool, this is appropriately sized.

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 has no output schema, so the description should explain what the tool returns. It only states 'check whether...valid', leaving the return format unstated. It also does not mention any preconditions or what 'valid' means. This leaves a significant gap for an agent trying to use the 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?

The input schema has zero parameters, so the baseline is 4. The description does not need to explain parameter semantics because there are none. It correctly does not add any irrelevant parameter information.

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 clearly states the tool's function: checking Telegram configuration validity for the MCP server. The verb 'check' is specific and the resource ('Telegram configuration') is unambiguous. This purpose is distinct from sibling tools like sending notifications or onboarding, so there is no confusion.

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 a clear usage context: use this tool when you need to verify that Telegram configuration is valid. While it does not explicitly mention alternatives or exclusions, the tool's purpose is clear enough that an agent would know when to invoke it. However, it lacks explicit guidance on when not to use it or which sibling to prefer.

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