uvcs_release_checkout_confirm

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

With destructiveHint=false already declared, the description usefully adds that locks are released and that modified files retain their checkout and edits, plus the approval-gate requirement. That is real behavioral context an agent could not infer from the annotations. It does not cover the response shape, but no output schema exists and the safety profile is adequately conveyed.

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?

Front-loads the core effect (release unchanged checkouts) before the constraints, which is the right ordering. Slightly redundant: "Requires prepare/confirm. Confirms and executes a prepared operation" repeats the same idea twice, costing a sentence.

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 two-parameter mutating tool with full schema coverage and no output schema, the description covers effect, safety, and the approval precondition. It omits only the return/result behavior, which is a minor gap.

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 100%, so both token and confirmPhrase are already documented, including the literal confirm phrase. The description only implicitly reinforces the token concept via "prepared payload" and "prepared operation," adding little beyond the schema. 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 verb (release) and resource (checkouts and their locks) with a clear scope qualifier: only files whose content did not change. It contrasts with the modified-file case, which makes the operation's boundary legible. It does not name the explicit sibling (uvcs_release_checkout_prepare) to route against, so it falls just short of a 5.

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?

Explicitly states the precondition: "Requires prepare/confirm" and "Call only after the user has reviewed the prepared payload and explicitly approved this exact operation." That is a concrete gate an agent can act on. It stops short of naming alternatives beyond the modified-files note and gives no explicit "do not call when…" guidance.

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