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

Annotations already declare destructiveHint=true and idempotentHint=true, so the description is not required to restate those. It adds useful context by mentioning version locking and task preparation after confirmation, but it does not clarify what destructive consequences locking may have, whether it is irreversible, or how confirmation_token and idempotency interact with the behavior.

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 with the main action front-loaded and no filler. 'Secure' and 'after confirmation' are slightly vague, but the overall structure is efficient 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?

For a 5-parameter mutation tool with no schema parameter descriptions and no explicitly identified workflow context, the description is too thin. It does not explain where this fits among the incorporation siblings, what happens to the case when locked, or how the optional confirmation_token alters behavior. The presence of an output schema reduces the need to describe return values, but operational context is still incomplete.

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 description coverage is 0%, so the description carries full responsibility for explaining parameters. It only hints at expected_version ('exact version') and confirmation ('after confirmation'), leaving case_id, project_id, idempotency_key, and confirmation_token semantics to inference.

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 states a specific action ('Lock an exact incorporation version') and resource ('prepare secure participant tasks'), which clearly conveys what the tool does. It also includes a precondition ('after confirmation'), helping distinguish it from read-only incorporation tools like get_case or validate, though it does not explicitly name sibling alternatives.

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 implies the tool should be used after confirmation, but it does not specify when to use it versus related incorporation tools such as validate, update_draft, or submit_to_sparklaunch. There is no guidance on prerequisites, ordering, or situations where this tool should be avoided.

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