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 but provides almost none. 'Reorder' implies a mutation operation, but the description doesn't indicate whether this requires special permissions, whether the reordering is immediate or batched, what happens to existing configurations during reordering, or any error conditions. For a mutation tool with zero annotation coverage, this represents a critical gap in behavioral transparency.

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 extremely concise ('Reorder the list of groups.') but this brevity comes at the cost of being under-specified rather than efficiently informative. While it's front-loaded with the core action, it lacks necessary context about what groups, why reorder them, or how the operation works. The single sentence doesn't earn its place by providing sufficient value beyond the tool name.

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?

Given that this is a mutation tool with no annotations, no output schema, and a completely inadequate description, the contextual completeness is severely lacking. The description fails to address what the tool actually does beyond the vague 'reorder' action, what the groups represent, what the expected outcome is, or any behavioral characteristics. For a tool that presumably modifies sensitive data scanner configurations, this level of documentation is dangerously incomplete.

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 0 parameters with 100% schema description coverage, so the schema already fully documents the empty parameter set. The description doesn't need to compensate for any parameter documentation gaps. However, the description doesn't add any parameter semantics beyond what's already in the schema (which indicates no parameters). The baseline for 0 parameters with high schema coverage is 4, as there's nothing additional needed.

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 'Reorder the list of groups' is a tautology that essentially restates the tool name 'update_sensitive_data_scanner_configs' without adding meaningful specificity. While it mentions 'groups' as the resource, it doesn't clarify what type of groups these are (sensitive data scanner configuration groups) or what 'reorder' operation entails. It fails to distinguish this tool from its siblings like 'update_sensitive_data_scanner_config_group' or 'create_sensitive_data_scanner_config_groups'.

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 absolutely no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, appropriate contexts, or relationships to sibling tools like 'get_sensitive_data_scanner_configs' (which presumably retrieves the current ordering) or other update/create/delete operations for sensitive data scanner configurations. The agent receives no directional information about when this specific reordering operation is appropriate.

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