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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so the safety profile is covered. The description adds genuinely new context beyond them: a per-user privacy boundary ('never exposes another user's alerts') and confirmation that alert state is not mutated. It does not mention pagination or result shape, but that is minor here.

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 sentences, zero filler, with the trigger condition front-loaded and the privacy constraint following. Nothing needs trimming.

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 values need no explanation, and the purpose/privacy story is complete. However, with 0% schema coverage the description should say something about the limit and state parameters, and it does not.

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% and neither parameter is named in the description. The phrase 'changes alert state' hints that 'state' refers to alert state, but the 'limit' parameter is entirely undocumented in both schema and description, leaving an agent to guess its meaning and default.

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+resource (review Smart Alerts) plus the scope (the authenticated user's own alerts and their valuation context). It is clearly distinct from get_my_portfolio/get_my_watchlist by naming the 'Smart Alerts' resource, though it never explicitly contrasts itself with those siblings.

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?

'Use this when the authenticated user asks to review their own ValuEdge Smart Alerts' gives a clear trigger condition. It stops short of naming an alternative tool or stating when not to use it, but the usage context is unambiguous.

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