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

Annotations already declare destructiveHint=true and readOnlyHint=false, and the description adds important procedural context: explicit user approval is required and the user is notified in Telegram. It could say more about irreversibility, but the safety workflow is well disclosed.

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 three short sentences with no wasted language. The destructive action and required approval step are front-loaded.

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 destructive two-parameter tool with complete schema coverage and destructive annotations, the description provides the essential approval and notification context. It does not describe the deletion result or confirm irreversibility, but the available structured fields cover most needs.

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 100%, so both feed_id and user_confirmed are already documented. The description reinforces the approval protocol for user_confirmed but adds little parameter meaning beyond the schema.

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: "Delete a feed." It also clarifies that deletion applies regardless of whether alerts are on or off, which distinguishes the action from alert/pause sibling tools.

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?

It gives a clear pre-call workflow: name the feed to the user, get approval, then pass user_confirmed: true. It does not explicitly mention alternatives such as set_feed_paused or update_feed, but the destructive context is clear.

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