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

Annotations already signal a non-read-only, non-idempotent, non-destructive write; the description adds that it writes a specific config file and requires human approval of the prepared payload before execution. It doesn't state whether the token is single-use, what happens on a stale token, or what success returns — modest gaps for a mutation tool that gives the agent useful operational safety context.

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-loaded with the concrete effect and file path; three short sentences with no filler. 'Requires prepare/confirm' and 'Confirms and executes a prepared operation' overlap somewhat, so one sentence could be trimmed.

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, two-phase confirm step with no output schema, the agent knows what it creates, the prerequisite, and the approval requirement. The only real omission is post-execution behavior (return value, failure modes on a stale token), which is minor at this complexity.

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% and both parameters are documented there, including the exact confirmPhrase literal and the token's source. The description adds no further semantics about token lifetime or format, so the schema does all the work per baseline.

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?

Names a specific verb and resource (creates .uvcs-mcp/style.json) and enumerates its contents: branch naming, checkin message, release conventions. The prepare/confirm framing also distinguishes it from the prepare sibling, though 'Create' versus 'confirms and executes' leaves slight ambiguity about whether this call or the prepare call actually writes the file.

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?

Explicit precondition: 'Requires prepare/confirm' and 'Call only after the user has reviewed the prepared payload and explicitly approved this exact operation' — a clear gate that tells the agent when not to call. The paired prepare tool is named only indirectly ('Requires prepare/confirm') rather than by its tool name, which lives in the schema instead.

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