update_security_signals_notification_rule

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

No annotations are provided, so the description carries full burden. It discloses that this is a partial update operation with optional fields, which implies mutation behavior. However, it doesn't mention authentication requirements, rate limits, whether changes are reversible, what happens when no fields are provided, or any side effects. For a mutation tool with zero annotation coverage, this is insufficient.

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 with just two sentences that directly convey the core information: the partial update operation and the optional field behavior. Every word earns its place with no redundancy or unnecessary elaboration.

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 mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what a 'security signals notification rule' is, what fields can be updated, what the response looks like, or any error conditions. The empty input schema means parameters aren't the issue, but overall context about this security-specific resource is missing.

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 input schema has 0 parameters with 100% schema description coverage, so there are no parameters to document. The description correctly states 'All fields are optional' which aligns with the empty schema. With zero parameters, the baseline is 4, and the description adds appropriate context about the partial update nature.

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 states the tool 'Partially update[s] the notification rule' which clarifies the verb (update) and resource (notification rule). However, it doesn't specify what a 'security signals notification rule' is or distinguish it from sibling tools like 'update_security_vulnerabilities_notification_rule' or 'update_monitor_notification_rule', making the purpose somewhat vague.

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 mentions 'All fields are optional' which is a usage constraint, but doesn't indicate prerequisites, when this partial update is appropriate versus full replacement, or how it differs from sibling notification rule tools.

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