get_dlp_rule

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

With no annotations, the description carries the burden of behavioral disclosure. It explicitly warns that the agent cannot modify or delete rules despite the Admin Console link permitting these actions. It also notes the response includes a direct link, which is a useful behavioral detail. However, it does not explicitly state whether the read operation has any side effects or permissions required, though 'retrieves details' implies a safe read.

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?

Two concise sentences front-load the core purpose and add a relevant behavioral note. No wasted words; every sentence adds value.

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?

The tool is simple with one parameter and an output schema. The description covers the purpose, a key response feature (Admin Console link), and an important limitation. Given the existence of an output schema, no further explanation of return values is needed.

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% with a clear description for the only parameter resourceName, including an example. The description adds little beyond the schema, merely restating 'by its resource name.' This meets the baseline for high schema coverage.

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 'Retrieves details for a specific Chrome DLP rule by its resource name,' with a specific verb, resource, and scope. It distinguishes itself from sibling tools like list_dlp_rules (which lists rules) and create_chrome_dlp_rule (which creates rules).

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 you need details for a known rule, indicated by 'by its resource name.' However, it does not explicitly mention alternatives or prerequisites, such as using list_dlp_rules to discover resource names, nor does it state when not to use this tool.

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