uvcs_release_checkout_prepare

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

Discloses the two-phase requirement and that the call returns a short-lived confirmation token — context not present in annotations. It also scopes the effect to unmodified files. It does not clarify that the prepare step itself performs no state change, which would resolve the apparent tension with readOnlyHint=true given the imperative 'Release checkouts' phrasing.

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?

Four tight sentences with the effect stated first and the workflow/token notes after; no filler. Slight redundancy between the opening claim and the modified-files caveat could be merged, but nothing is wasted.

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 one-parameter prepare tool with no output schema, the description covers effect, safety scoping, workflow prerequisite, and return value. Missing only the explicit note that no repository change occurs until confirm.

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 100% with a single well-documented 'paths' parameter, so the schema carries the semantics. The description adds nothing about path format, workspace root, or the 200-item cap, so baseline 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?

States a specific operation: release checkouts and locks, but only for files whose content did not change, and spells out the contrasting behavior for modified files. An agent can tell this apart from sibling prepare/confirm pairs without opening the schema.

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?

Makes the prepare/confirm workflow explicit and redirects the agent for modified files ('check those in or undo them'), which is genuine routing guidance. It never names the confirm sibling directly (uvcs_release_checkout_confirm) or states exclusions such as what happens with files checked out by another user.

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