Behavior3/5

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

No annotations exist, so the description must disclose behavior. It explains parameters and defaults, but does not state whether the operation is read-only, requires authentication, or any side effects. The lack of transparency leaves the agent uninformed about operational characteristics.

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 brief and front-loaded with the purpose. The 'Args' section is clear and structured. It could be more concise by removing the 'Args' label and integrating parameter explanations more naturally, but overall it is efficient.

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

Completeness3/5

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

Given the presence of an output schema, return values are covered. The description is adequate for a simple retrieval tool but could mention pagination, error handling, or data freshness. The tool has three parameters, and the description covers them sufficiently, but not exhaustively.

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?

With 0% schema description coverage, the description fully explains the parameters: start_date and end_date formats and defaults, and use_v2_goals meaning. This adds significant value beyond the schema. However, it could clarify acceptable date ranges or behavior when parameters are omitted.

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 states 'Get budget information from Monarch Money' which identifies the verb and resource, but it is generic and does not differentiate from sibling tools like get_cashflow or get_transactions_summary. A more specific purpose (e.g., retrieving budget allocations or progress) would improve clarity.

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. The description does not mention prerequisites, limitations, or exclusions. The agent gets no context for selection among many financial data tools.

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