manage_key_lifecycle

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

Provides standard reference and action list, but lacks disclosure of side effects, permission requirements, or irreversible actions. With no annotations, description adds some context but remains incomplete.

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?

Starts with clear purpose statement, then structured list of actions and parameters. No redundant sentences, but the description could be more front-loaded with essential context.

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?

Covers actions and parameters adequately, but lacks examples, error handling, or ordering of operations. Output schema exists but not explained. Adequate for a complex tool but with noticeable gaps.

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 has 0% description coverage. Description compensates by explicitly listing each parameter with its purpose and applicable context, especially for actions. Clear mapping of parameters to actions.

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?

Clearly states 'Manage cryptographic key lifecycle per NIST SP 800-57' and enumerates specific actions. Distinct from sibling tools which focus on specific cryptographic operations or compliance checks.

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?

Implied usage via action list, but no explicit guidance on when to use this tool versus alternatives like generate_key or validate_key. No when-not or alternative references.

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