check_action_compliance

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It indicates the tool returns a ranking and risk indicator (non-mutating checkout), but does not explicitly state whether it is read-only, has side effects, requires authentication, or has rate limits. The absence of such details leaves some behavioral ambiguity, though the 'pre-flight' metaphor suggests safety.

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 two sentences with no wasted words. The first sentence front-loads the core purpose ('Pre-flight compliance check') and provides immediate clarity. The structure is efficient, using a colon to introduce details and examples. Every sentence serves a purpose: defining the tool, giving examples, and stating its role.

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 the tool has three parameters with full schema coverage and no output schema, the description covers the essential aspects: input format, output (ranked list + risk indicator), and use case. It could be more complete by mentioning whether the check is real-time or cached, or confirming that it is non-destructive. However, it is sufficient for an agent to select and invoke the tool correctly.

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?

The input schema has 100% description coverage, providing baseline semantics for all three parameters. The tool description adds significant value by explaining the 'action' parameter usage with concrete examples and clarifying that 'jurisdiction' is a hint. It also implies a default limit of 10 (from 'max 25' in schema) and describes the output format. This extra context elevates the parameter understanding beyond the schema alone.

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 function: a 'pre-flight compliance check' that takes an action description in natural language and returns a ranked list of regulations and a risk indicator. It uses specific verbs and nouns, and the examples ('process EU resident biometric data') make the purpose unmistakable. The phrase 'headline runtime gate for autonomous agents' further distinguishes it as a proactive compliance tool, though it does not explicitly differentiate from sibling tools.

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 provides usage context (when to assess an action before execution) and gives examples of input, which implies when to use. However, it does not mention when NOT to use this tool or suggest alternatives among the siblings (e.g., browse_topics, compare_jurisdictions). An agent would need to infer usage boundaries from the tool's name and purpose.

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