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

Annotations already declare this as a read-only, idempotent, non-destructive, closed-world lookup, so the safety profile is covered. The description adds useful content-scope context (which foreclosure aspects are included), but says nothing about freshness, jurisdiction limits beyond 'US', or whether data is ever trimmed — acceptable but not rich for a pure reference tool.

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 tight sentence with no redundancy, and the jurisdiction is front-loaded. The all-caps 'UNITED STATES.' fragment is a slightly awkward stylistic lead-in, but it does signal scope immediately.

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 one-parameter lookup with no output schema, the description carries the burden of stating what comes back — and it does, enumerating the five content areas. Safety is handled by annotations, so nothing critical is missing; only usage routing and data-freshness notes are absent.

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?

There is a single parameter with 100% schema description coverage documenting accepted names and two-letter codes, so the baseline is 3. The description's 'by state' phrasing confirms the axis of lookup but adds no format or edge-case detail 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?

The description names a specific resource — the US state-level foreclosure process — and enumerates the exact facets returned (judicial vs. trustee sale, timeline, redemption, deficiency judgments, mediation). That is far more informative than the title alone, though it never explicitly distinguishes itself from the adjacent US reference tools such as state_overview_us.

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 statement of when to reach for this tool versus its many US siblings (state_overview_us, federal_guide_us, seller_disclosure_us, etc.), and no prerequisites or exclusions. The agent must infer usage from the topic alone.

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