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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuine context beyond that: strict per-user scoping and the guarantee that alert state is never mutated. It stops short of describing result volume or how paging behaves relative to the limit parameter.

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 tight sentences with the usage trigger front-loaded and the boundary guarantees after it. No filler, no restatement of the title.

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 not be explained, and the read-only, own-data contract is clear. The missing piece is the state filter: for a two-parameter list tool where the only meaningful filter has an open-ended string type, the definition leaves the agent guessing at valid inputs.

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% for two parameters, and the description compensates for neither. The free-text 'state' filter (anyOf string up to 40 chars) is left completely undefined — an agent has no idea what values are valid — and 'limit' is only implied by nothing at all.

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 names a specific resource ('ValuEdge Smart Alerts and the valuation context behind them') and the act of reviewing them, so the intent is unambiguous. The 'my' scoping distinguishes it from the portfolio/watchlist siblings, though it never explicitly contrasts with them.

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...' gives a clear triggering condition. It also gives exclusions — never exposes another user's alerts, never changes alert state — but does not point at any sibling alternative for related tasks.

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