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

With no annotations, the description carries the full load and does so well: first-page-only cap of 5 rows, no pagination input, empty result is not a safety finding, no completeness/freshness/identity guarantee, and a per-call cost of 0.011 USDC. These are exactly the traits an agent cannot get from structured fields.

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?

Purpose is correctly front-loaded, but the caveats are repetitive: 'No completeness or safety guarantee' restates the earlier 'no independent entity identity, freshness, completeness...' and 'Empty is not a safety finding'. Several clauses could be merged without losing meaning.

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?

Given no annotations, no output schema, and an opaque argument bag, the description covers behavior, cost, and result limits, and routes the agent to the schema tool for parameter structure. It is reasonably complete for a small lookup tool, with the argument contract being the only real hole.

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 0% and the single 'arguments' object is an opaque additionalProperties bag, so the description must compensate. It does point to company_id as the source (cn_data_v3_company_detail) and redirects to get_cn_data_tool_schema for the argument shape, but it never describes the fields inside the arguments object.

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: query enterprise standard name, level, and status, which is enough to distinguish it from standard_count (numeric rollup) and standard_detail (single record). It never names those siblings, so differentiation is inferred rather than explicit.

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?

Gives a prerequisite (use company_id from cn_data_v3_company_detail) and a hard usage constraint (provider first page only, max 5 rows, no pagination input). It does not say when to prefer this over cn_data_v3_standard_count or cn_data_v3_standard_detail, so the choice among the three standard tools is left implicit.

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