List eToro price alerts

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

Beyond the annotations (which already cover read-only/idempotent/non-destructive), the description adds genuinely useful behavioral context: the permission scope required and the scoping rule that 'alerts belong to the account, not to demo or real'. This is real value the annotations do not convey.

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 and dense but not bloated; the field list is packed into one sentence. Slightly run-on, but every clause carries information.

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?

With no output schema, the description usefully documents the return fields, plus the permission requirement and data scope. Fairly complete for a simple parameterless read tool; minor gaps are unstated ordering or volume of alerts.

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?

Zero parameters, so there is nothing to document; the baseline for a parameterless tool is 4. The description's field enumeration is return-value context rather than parameter semantics.

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?

Clear specific verb+resource: 'List the user's active price alerts'. It even enumerates the returned fields (instrument, target price, bid, direction, distance). It does not name a sibling alternative, but no other price-alert tool exists among the siblings, so differentiation is not strictly needed.

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?

Usage is implied (retrieve active alerts) rather than explicitly framed, and no when-not or alternatives are given. It does state a prerequisite ('Needs the key's price-alerts Read permission'), which is a partial usage signal.

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