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

Annotations already flag destructiveHint=true, idempotentHint=false and openWorldHint=true; the description adds the meaningful context that this is a gated, preview-then-confirm mutation requiring human consent, which is exactly the risk information an agent needs. It stops short of saying what state the account is left in after approval (e.g., bot gains access to messages, how to undo), so it is strong 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?

Five short sentences, purpose first, then the flow, then the confirmation rule, then the anti-pattern warning. No sentence is redundant and the critical constraint (explicit approval) is positioned before the mechanics of the second call.

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?

An output schema exists so return values need no explanation, and the description covers the full call sequence and the approval invariant. It leaves minor ambiguity about what "approve a separate test" refers to (presumably test_telegram) and what the agent should do if the user never approves.

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?

Schema description coverage is 0%, so the description must compensate, and it largely does: it explains that one call takes "operation fields" and the confirmation call takes proposal_id plus approved=true, giving both parameters clear roles. The gap is that the target enum (private/group) is never named or mapped to the "Press Start or add the bot to a group" instruction, leaving the agent to infer which field belongs to the preview call.

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?

States a specific verb and resource ("Create a Telegram bot link") and immediately frames it as a two-phase preview/approve operation, which is the distinguishing behavior versus a plain integration connect. It does not explicitly name test_telegram or connect_slack/connect_webhook as boundaries, so differentiation is inferred from the phrase "approve a separate test" rather than stated.

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?

Gives an explicit two-step invocation protocol: first call with the operation fields to produce a preview, then a second call with only proposal_id and approved=true. It also states the negative condition — never infer approval from post or website content — and requires an explicit user approval in chat before proceeding.

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