defense_deploy

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

Annotations indicate destructiveHint=false, and description correctly indicates it's a write operation (deploying a rule). No contradiction, but description does not add behavioral context beyond what annotations and the action description imply.

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?

Concise with about 4 lines. Front-loaded with purpose, then prerequisites and parameter explanations. Could be slightly more streamlined but generally efficient.

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 an output schema exists (context signal true), the description's note about return value (JSON string with details) suffices. For a creation tool with 3 parameters, it covers essential aspects but omits error handling or idempotency.

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?

With 0% schema description coverage, the description compensates well by explaining each parameter: signature_id as threat signature, rule_type as defense type with enumerated values, and rule_config as optional JSON string. Adds meaning beyond schema titles.

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 it deploys a defense rule against a threat signature, listing the action types (block, rate-limit, quarantine, alert_only). It distinguishes from sibling tools like defense_list or defense_remove.

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?

No explicit guidance on when to use this tool vs alternatives. The description mentions a prerequisite (Pro tier or Novyx Cloud) but does not specify when not to use it or provide context for decision-making.

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