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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It mentions atomicity but does not explain side effects (e.g., state mutation, idempotency, error behavior, or consequences of invalid leases/versions).

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 a single concise sentence that efficiently conveys the core functionality. No redundant fluff; it is well-structured and easy to parse.

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's complexity (5 parameters, enum, constraints), the description is insufficient. It omits parameter details, expected output, and edge-case behavior, leaving an agent with inadequate information to use the tool correctly without further investigation.

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 coverage is 0%, and the description provides minimal parameter insight. It only vaguely references 'lease and version' without mapping them to the actual parameters (id, lease, action, result, expected_version), leaving their meanings and constraints entirely undisclosed.

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: to atomically perform specific task lifecycle actions (claim, renew, release, block, reopen, complete) using a lease and version. It is specific and distinguishes it from sibling tools that handle notes, credentials, or searches.

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 lists the actions but does not explicitly state when to use this tool versus alternatives or when to choose each action. It implies usage for task coordination but lacks explicit guidance on conditions or prerequisites.

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