Behavior2/5

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

With no annotations provided, the description bears full responsibility for behavioral transparency. It only reveals that the query is not executed, but omits other important traits like side effects, read-only nature, required permissions, or what 'bounded' means. This is insufficient for a tool with 10 parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence, front-loading the key purpose. However, given the tool's complexity (10 parameters, many siblings), a slightly more structured approach could improve usability without sacrificing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is markedly incomplete given the tool's complexity: no output schema, no annotation context, no parameter guidance, and only a high-level purpose. It fails to provide enough context for an AI agent to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, yet the description does not explain any of the 10 parameters (e.g., sql, format, params, schema). The description adds no meaning beyond the schema, which itself lacks descriptions. This is a critical gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: generating bounded JSON or Markdown documentation for a SQL snippet without executing it. The verb 'Generate' and resource 'documentation for a SQL snippet' are specific, and the 'without executing' clause distinguishes it from sibling tools that execute or analyze query plans.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use (for documentation without execution) but does not provide explicit guidance on when not to use or how it compares to alternatives like ob_explain or ob_generate_query. Given many siblings, more explicit differentiation would improve scReadabilitycores.

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