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

With no annotations provided, the description carries full burden for behavioral disclosure but offers none. It doesn't indicate whether this is a read-only operation, what permissions are required, whether it's idempotent, what happens if the rule doesn't exist, or any rate limits. The description provides no behavioral context beyond the basic action implied by 'get'.

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 at just four words. It's front-loaded with the core action and resource. There's zero wasted language or redundancy. For a simple retrieval tool with no parameters, this brevity is appropriate rather than under-specified.

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 the tool has no parameters (simplifying input) but also no annotations and no output schema, the description is incomplete. It doesn't explain what 'details' include, the response format, error conditions, or behavioral constraints. For a security monitoring rule retrieval tool, more context about what information is returned would be helpful despite the simple parameterless nature.

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 (empty schema). The description doesn't need to explain parameters since there are none. A baseline of 4 is appropriate for zero-parameter tools where the schema fully covers the absence of inputs.

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 'Get a rule's details' is a tautology that essentially restates the tool name 'get_security_monitoring_rule'. It specifies the verb 'get' and resource 'rule's details' but lacks specificity about what kind of rule (security monitoring) or what details are retrieved. It doesn't distinguish from siblings like 'get_security_monitoring_rules' (plural) or 'get_security_monitoring_rule_convert'.

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 prerequisites, context, or differentiate from sibling tools like 'get_security_monitoring_rules' (which likely lists multiple rules) or 'update_security_monitoring_rule' (which modifies rules). There's no indication of when this retrieval operation is appropriate.

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