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

With no annotations, the description carries the transparency burden, and it does well by disclosing the authoritative data source, the fact that it returns a defined set of status-related fields, and the confirm-only purpose. It does not mention pagination/limit behavior, possible status values, or data freshness, which would make the behavior fully transparent.

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 sentences deliver source, authority, output fields, and intended use with no filler. The key scoping phrase 'authoritative statutory status' is front-loaded, making the tool easy to scan.

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?

No output schema exists, so the description compensates by listing the returned fields and the statutory-purpose framing. Given the simple optional-parameter input schema, the main omission is not explaining default behavior when no parameters are supplied or how this differs from search_compounds.

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 coverage is 67%: city and mispar are described in the schema, and the description adds little parameter-specific meaning beyond mentioning compound number as a return field. The limit parameter is not described in either the schema or the description, though its type, default, min, and max are given in 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 clearly identifies the tool as a lookup of authoritative statutory status for Israeli pinui-binui compounds from the government registry, and lists the concrete fields returned. It does not explicitly contrast itself with siblings like search_compounds or get_compound_details, missing the explicit differentiation needed for a 5.

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 final sentence gives an explicit use case: confirm a compound is officially declared and at what statutory stage. However, it does not state when not to use this tool or name an alternative tool for related lookups, so it earns a 4 rather than 5.

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