get_pii_config

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

With no annotations provided, the description carries the full behavioral burden. '获取' clearly signals a read-only retrieval operation, which is useful, but the description does not disclose what the returned configuration contains, whether it depends on the active profile, or what format the response takes.

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 short sentence that is front-loaded and free of filler. It is appropriately compact for a no-parameter getter, though it is terse enough that it leaves usage and behavioral details to inference.

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?

Invocation is simple because there are no parameters, but with no output schema and no annotations, the description is thin. An agent can call the tool correctly but will not know what shape or scope of PII configuration to expect in the response.

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 tool has zero parameters and the schema has 100% coverage with an empty properties object, so parameter semantics are trivially clear. The description does not need to add parameter-level detail.

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 uses a specific verb ('获取') and a specific resource ('PII 脱敏配置'), making it clear this tool retrieves PII masking configuration. It is distinguishable from the sibling 'set_pii_config' by the get/set contrast, though it does not explicitly delimit scope such as current, global, or profile-specific config.

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?

There is no guidance on when to use this tool versus alternatives, no mention of the sibling 'set_pii_config', and no prerequisites such as an active profile. The agent must infer the usage context from the tool name and the getter semantics.

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