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

As a read operation, the description implies no side effects, but it does not disclose behaviors like error handling for missing ids, authentication requirements, or rate limits. Without annotations, more could be expected, but the description does indicate the return is the 'complete content', which adds some 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?

The description is one short, front-loaded sentence that immediately conveys the purpose. No wasted words.

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 single-parameter read tool, the description is mostly complete. It indicates the result is the full record content. It doesn't cover error behavior (e.g., not found), but the low complexity makes this 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?

Schema description coverage is 100% as the only parameter 'id' is already described as 'record id (required)'. The description adds no new meaning beyond 'by id', so baseline 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 clearly states the action: 'view the complete content of a single record by id' (按 id 查看单条记录的完整内容). The verb 'view' and resource 'single record by id' are specific, and it distinguishes from siblings like vault_list (listing records) and vault_ask (querying).

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 when a single record's full content is needed by id, but it does not explicitly provide when-to-use vs alternatives or any exclusions. No mention of when to prefer vault_list or vault_ask instead.

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