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

No annotations are provided, so the description carries the full burden. It implies a persistent registration (a mutation), but says nothing about required permissions, whether the token is validated, whether the operation is reversible, or what happens on failure.

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?

A single front-loaded sentence with no filler. It is efficiently sized for a one-parameter tool, though thin on substance.

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?

For a registration-style tool with no annotations and no output schema, the description omits prerequisites, side effects, and outcome. An agent knows the intent but little else required to invoke it confidently.

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?

Only one parameter exists and the schema is 0% described, but the description's phrase 'using bot token' does map the single input to its meaning. That is the minimum needed; no format, source, or validation detail about the token is added.

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 states a specific verb and resource: 'Add Telegram channel ... using bot token'. It conveys what the tool does clearly enough, though it uses the hyphenated name verbatim and doesn't differentiate itself against the sibling tools beyond the Telegram context.

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 when-to-use or when-not-to-use guidance is provided. It does not say when this is preferable to the sibling telegram-pairing-approval path, nor what prerequisites exist for using a bot token.

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