set_budget_alert

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

The description includes a detailed 'Behavioral Transparency' section covering side effects, authentication, rate limits, etc. However, it contradicts itself by first saying it sets an alert (implying mutation) and then claiming it is read-only and stateless. This internal inconsistency undermines 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 long and repetitive, with a 'Behavior' section followed by a near-duplicate 'Behavioral Transparency' section. The first sentence is contradictory. Important information is not front-loaded; the most critical purpose is muddled.

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 4 parameters and 0% schema coverage, the description should fully explain each parameter's role. It does not. The tool has an output schema but the description does not mention return values. The contradictory nature leaves the agent uncertain about whether this tool mutates state or not.

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 schema has 0% description coverage, and the description's 'Args' section merely lists parameter names and types with generic descriptions (e.g., 'The month to analyze or process'). It adds no meaning beyond the schema. The tool's parameters like 'threshold_percent' are not explained in context of setting an alert.

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 opens with 'Set spending alert threshold for a category' suggesting a write operation, but then the behavior section claims it is read-only and produces analysis output. This contradiction obscures the actual purpose, making it unclear whether the tool modifies state or just analyzes.

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 'When to use' and 'When NOT to use' sections are generic and not specific to setting a budget alert. The guidance mentions 'structured analysis or classification' which does not align with the tool name or the parameters (month, category, threshold, api_key). No sibling differentiation is provided.

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