lock

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

With no annotations, the description fully carries the burden of behavioral disclosure. 'Lock an object' reveals nothing about side effects, permissions, concurrency implications, error states, or what locking entails. This is critically insufficient.

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 extremely concise (one short sentence) but fails to be useful. Conciseness should not come at the cost of informativeness. Every word should add value, but here no value is added beyond the tool name.

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 no output schema, no annotations, and three parameters, the description is vastly incomplete. It omits return values, required permissions, behavior on failure, and any context for the locking operation. The agent would have to guess or experiment.

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 already describes all three parameters with full coverage. The description adds no additional meaning beyond what the schema provides (e.g., objectUrl, accessMode, connection). Baseline score 3 applies.

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 'Lock an object' provides a verb and resource, conveying the basic action. However, it is vague—'object' is unspecified, and it lacks differentiation from sibling tools like 'unLock' or other lock-related operations. The purpose is minimally clear but not precise.

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 guidance is provided on when to use this tool versus alternatives or any prerequisites. The description does not mention context, exceptions, or related tools, leaving the agent to infer usage without help.

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