Behavior2/5

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

No annotations are provided, so the description carries full burden. It implies a mutation ('Updates') but doesn't disclose behavioral traits such as required permissions, whether changes are reversible, rate limits, or what the response looks like. This is a significant gap for a mutation tool with zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words, making it appropriately sized. However, it's front-loaded but lacks depth, which is efficient but under-specified for a mutation tool, slightly reducing its effectiveness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (a mutation with no annotations, no output schema, and 0 parameters), the description is incomplete. It doesn't explain what fields can be updated, the expected behavior, or return values, leaving critical gaps for an agent to use it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0 parameters with 100% coverage, so no parameters need documentation. The description mentions 'by `rule_id`', which hints at an identifier but isn't a parameter in the schema, adding minimal context. Baseline is 4 for zero parameters, as the schema fully covers the absence.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Updates a monitor notification rule by `rule_id`' states the verb ('Updates') and resource ('monitor notification rule'), which clarifies the basic purpose. However, it's vague about what specific aspects are updated and doesn't differentiate from sibling tools like 'update_monitor' or 'update_monitor_policy', leaving ambiguity about scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing rule_id), exclusions, or compare to siblings like 'create_monitor_notification_rules' or 'delete_monitor_notification_rule', leaving the agent to infer usage context.

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