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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's value is in adding result behavior: newest-first ordering, service times/places returned in local time with timezone, and a link per notice. That is meaningful context beyond the annotations, though ordering stability and no-match behavior are not addressed.

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?

Three tight sentences: purpose and filters first, then ordering, then return payload. No filler and nothing that duplicates structured fields verbatim.

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?

With no output schema, the description usefully compensates by summarizing the return payload (service times, places, notice links). It is nearly complete for a search tool; only the empty-parameter behavior and result-count expectations are left unstated.

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 all six parameters are already documented with ranges, enums and defaults. The description restates three of the facets but adds no syntax, matching rules, or semantics beyond what the schema provides, so baseline 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?

States a specific verb (search) and resource (published death and funeral notices) and names the filterable facets (name, service location, funeral home). It does not differentiate itself from siblings such as get_notice or search_memorials, so an agent must infer the boundary, but the purpose itself is unambiguous.

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 mention of filtering by name/location/funeral home implies when this search is appropriate, and "published" implies a read-only lookup. However, there is no explicit guidance on when to use this versus get_notice (single notice retrieval) or search_memorials/search_funeral_directors, nor any note about what happens when no parameters are supplied.

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