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

Annotations already declare readOnlyHint/idempotentHint, but the description adds information not in them: `setting` is null when Telegram is not linked, a wallet-signature identity is required, and the paired update tool performs whole-object replacement. Those null semantics and the auth prerequisite are the main things that could cause a caller to misbehave.

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?

Front-loaded with the verb and resource, then the routing guidance, then caveats — good ordering with no filler. The parenthetical field inventories are somewhat redundant given an output schema exists, which trims the score slightly.

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 zero-parameter read tool with an output schema, everything an agent needs is present: what is returned at a high level, the null case, the auth requirement, and the correct sibling for in-app alerts and for mutations. Nothing essential is missing.

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?

There are zero parameters, so the baseline is a 4. The description instead describes semantics of the returned `setting` object and its null condition, which is a useful addition even though it sits in output-schema territory.

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 ('Read the Telegram alert filters of the logged-in user') and immediately enumerates the two filter groups (seller: remaining amount, duration, price/APY ranges, unlocked-only; buyer: reclaim warning time, low energy/bandwidth thresholds). This clearly differentiates it from tronsave_update_telegram_notify_setting and tronsave_list_notifications.

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?

Explicitly routes the agent: read this before calling tronsave_update_telegram_notify_setting, and notes that the update tool replaces whole filter objects (so read-modify-write is required). It also names tronsave_list_notifications as the alternative for in-app alerts, which is exactly the sibling-disambiguation an agent needs.

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