delimit_cost_alert

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

No annotations are provided, so the description must carry behavioral disclosure. It only says 'CRUD operations' and 'file-based', but the input schema reveals actions include 'toggle' (not typical CRUD), and 'file-based' is unexplained. No mention of required permissions, side effects, or whether operations are reversible.

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 a single sentence, which is concise. However, the prefix '(Pro)' and 'file-based' add potential confusion without explanation, slightly reducing clarity for the sake of brevity.

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 4 parameters, an output schema (not shown), and no annotations, the description is too minimal. It fails to explain the 'file-based' concept, how the 'toggle' action works, or what triggers alerts. The output schema may provide return format, but the description lacks sufficient behavioral and contextual information.

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 100% description coverage for all 4 parameters, so the schema already explains each parameter. The description adds no additional meaning beyond listing CRUD operations; it does not clarify parameter relationships (e.g., when name vs. alert_id is required). Baseline score of 3 is appropriate.

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 manages cost alerts with CRUD operations on spending thresholds, which is specific to the resource. It is distinguishable from sibling tools like delimit_cost_analyze or delimit_cost_controls, which focus on analysis and controls respectively. However, the term 'file-based' is ambiguous and could be clarified.

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, nor does it explain when to perform specific actions (e.g., create vs. delete). The input schema lists actions but the description omits usage context, leaving the agent to infer from parameter names alone.

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