get_dynamic_group

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a read operation ('get'), but doesn't mention authentication requirements, rate limits, error conditions, or what happens if the dynamic_group_id is invalid. It partially describes the return format ('detailed dynamic group information including matching rules'), but lacks specifics on structure or completeness.

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 well-structured and appropriately concise: a clear purpose statement followed by Args and Returns sections. Every sentence adds value, with no redundant information. It could be slightly more front-loaded by integrating the parameter explanation into the main sentence.

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 read operation with one parameter and no output schema, the description is minimally adequate. It covers the basic purpose and parameter meaning, but lacks behavioral details (like error handling) that would be helpful given the absence of annotations. The mention of return content ('matching rules for instance principals') partially compensates for no output schema.

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 description adds meaningful context for the single parameter: 'dynamic_group_id: OCID of the dynamic group to retrieve.' This clarifies that the ID is an OCID (Oracle Cloud Identifier) and specifies its purpose. With 0% schema description coverage and only one parameter, this adequately compensates, though it doesn't explain OCID format or validation rules.

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 tool's purpose: 'Get detailed information about a specific dynamic group.' It uses a specific verb ('get') and resource ('dynamic group'), but doesn't explicitly differentiate it from sibling tools like 'get_group' or 'list_dynamic_groups' beyond mentioning it's for a 'specific' dynamic group.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'list_dynamic_groups' (for listing groups) or 'get_group' (for static groups), nor does it specify prerequisites or contextual constraints for retrieving a specific dynamic group.

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