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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the useful scoping fact that only the authenticated user's alerts are returned, plus the enum-like categorization into price/event/clock alerts, but says nothing about ordering, pagination cursor behavior, or what happens when offset exceeds the total.

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 purpose sentence followed by a compact Args block; no filler. The Args section partly restates schema defaults, but that redundancy is the intended compensation for 0% schema description coverage.

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?

An output schema exists, so return shape need not be described. The alert categories, user scoping, and pagination parameters are all covered; the remaining gap is the absence of any note about ordering or total-count limits for paging through large alert sets.

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 0%, so the description must carry the parameter burden and largely does: offset is explained as 'Skip this many alerts (default 0)' and limit as 'Page size (default 50, max 100)'. The max of 100 is a real constraint absent from the schema, though the two parameters' interaction (offset must be a multiple of limit, etc.) is unstated.

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 (list) and resource (alerts) and narrows scope to 'price, event, and clock alerts for the authenticated user', which is more specific than the title. It does not name a sibling explicitly, but the list-vs-create/delete distinction against create_alert and delete_alert is obvious from the verbs.

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 description gives no when-to-use context and no comparison to plausible alternatives such as get_notifications. The only usage signal is the implicit scoping of 'for the authenticated user', which is context, not guidance.

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