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

Goes well beyond the annotations: it discloses that the call is a full replacement requiring COMPLETE filter objects, states the auth prerequisites (wallet signature identity plus linked Telegram account), and reassures that no funds move. 'Idempotent' restates idempotentHint=true but adds nothing harmful.

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?

Four compact sentences, front-loaded with the action and the key replace-semantics warning. Minor redundancy in explaining that each range carries `isEnabled` plus numbers, which the schema already states explicitly.

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 mutation tool with nested, fully specified parameters and an output schema, the description supplies everything else an agent needs: replacement semantics, prerequisite identity/account state, and the safety profile that no funds are at risk.

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% with fully documented nested objects, so the schema carries parameter definitions. The description still adds essential meaning the schema cannot: that each object is sent whole rather than patched, and that omission leaves that side unchanged.

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 ('Replace the Telegram alert filters') and explicitly points to the sibling read tool `tronsave_get_telegram_notify_setting`, so the agent can distinguish it from the getter without opening either schema.

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 a concrete read-edit-write workflow ('read the current ones with ... edit, send back') and clarifies the scope of effect ('Only changes which alerts are sent; no funds move'). It names the alternative read tool but does not state when not to use this tool (e.g., when no Telegram account is linked beyond the prerequisite note).

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