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

Annotations already provide readOnlyHint=false, idempotentHint=true, and destructiveHint=false, indicating a non-destructive, idempotent mutation. The description adds the purpose context (authentication for watch daemon) but does not disclose any additional behavioral details beyond what annotations imply. It does not contradict annotations.

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 that states the action and purpose, with no redundant wording. It is front-loaded with the core action and immediately clarifies context.

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 simple tool with one parameter, no output schema, and annotations covering idempotency and destructiveness, the description is adequate. It explains what it does and why, leaving no major gaps for an agent to invoke it correctly. A slight gap exists in not specifying any prerequisites or effects on existing fingerprints, but given the tool's simplicity, this is acceptable.

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 schema covers all parameters (password with description '新密码'), and the description does not add extra meaning beyond that. It does not explain password format, encoding, or any constraints, but with 100% schema coverage, the baseline of 3 is appropriate.

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 verb (update) and resource (password fingerprint), and clearly mentions the purpose (used for watch daemon authentication). This distinguishes it from all sibling tools, which focus on logging, hooks, git, CI, lock/unlock, init, write, and status operations.

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 usage by mentioning the watch daemon authentication, but it does not explicitly say when to use this tool vs alternatives, nor does it exclude other tools. There is no mention of when not to use it or any prerequisites, leaving some ambiguity.

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