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

With no annotations, the description carries the full burden, and it does add real behavioral detail: it names the trigger conditions (30%+ drops between the last two iXBRL accounts, negative net assets, status changes) and states results are 'sorted by severity'. It stops short of describing auth needs, pagination, or whether it is strictly read-only, though the get_ prefix implies a read.

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?

A single dense sentence that front-loads the resource and then enumerates alert types; every clause carries meaning. The long enumeration is justified by the breadth of alert categories, though it reads as a run-on list.

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 read-only list tool with no output schema, the description explains what is returned and how it is ordered, which is most of what an agent needs. The 'since' parameter's 30-day default in the schema covers the time window, leaving only minor gaps around result volume or truncation.

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 'since' and 'severity' (with its enum) are already fully documented in the schema. The description adds nothing about parameter syntax or defaults, so the standard baseline of 3 applies.

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 resource ('Monitoring alerts for your watchlist') and enumerates the concrete alert categories returned, so an agent knows exactly what this tool surfaces. It does not, however, distinguish itself from siblings like find_triggers or recent_changes, which cover adjacent territory.

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?

There is no explicit guidance on when to call this versus alternatives such as find_triggers, recent_changes, or watch_list. Usage is only weakly implied by the phrase 'for your watchlist'; no prerequisites or exclusions are given.

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