Price alerts

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered structurally. The description adds one genuine behavioral fact beyond that: results are paged. It does not describe page size limits, sorting, or what happens on out-of-range pages.

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?

Two short sentences with the resource front-loaded and no filler. 'Paged.' as a fragment is terse but functional; nothing wastes space.

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 and annotations covering safety, the remaining burden is explaining the two undocumented paging parameters and the relationship to the singular get_alert sibling; neither is addressed. Adequate but with clear gaps for a 4-parameter tool.

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 coverage is 50%: market and symbol are documented in the schema, while page and pageCount are undocumented anywhere. 'Optionally only for one instrument' loosely maps to symbol and 'Paged' loosely to the paging params, but no defaults, ranges, or format details are added 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?

Identifies a specific resource (price alerts of the account) with a scope qualifier (optionally one instrument) and a paging note. It is clearly distinguishable from create_alert/update_alert/delete_alert, but it does not distinguish itself from the singular sibling get_alert, which shares a very similar name.

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?

The phrase 'optionally only for one instrument' implies the filter condition for narrowing results, but there is no explicit when-to-use guidance and no mention of how this differs from get_alert (singular), the closest sibling. Usage is only implied.

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