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

With no annotations provided, the description fully carries the burden of behavioral disclosure. It states: 'This tool generates structured output without modifying external systems. Output is deterministic for identical inputs. No side effects. Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage.' This is comprehensive and 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?

The description is well-structured with labeled sections (Args, Behavior, When to use, When NOT to use) but is somewhat verbose. It front-loads the core purpose but could be tighter without losing clarity.

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?

The description covers purpose, parameters, behavior, and usage guidance. Given the presence of an output schema, it appropriately avoids explaining return values. However, it misses the 'api_key' parameter, which slightly reduces completeness.

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 0%, so the description must compensate. It lists parameters with explanations and examples (e.g., 'implemented_controls: List of implemented SOC 2 criteria IDs (e.g. ["CC1.1", "CC6.1", "A1.1"])' and 'target_type: "type1" (point-in-time) or "type2" (period of time)'). However, it omits the 'api_key' parameter present in the schema, making coverage incomplete.

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 states the tool's purpose: 'Gap analysis against SOC 2 controls. Compares implemented controls to required criteria and produces a prioritized remediation plan.' This is a specific verb-resource combination that distinguishes it from sibling tools like 'assess_trust_principles' or 'crosswalk_to_iso27001'.

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 description includes explicit 'When to use' and 'When NOT to use' sections, providing clear guidance on when the tool is appropriate (e.g., for compliance assessment, gap analysis) and when it should not be used (e.g., as a substitute for legal counsel).

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