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

Annotations already indicate this is a safe, read-only, non-destructive, idempotent operation with deterministic output. The description adds valuable context about what the tool actually produces ('complete, personalized Zero-Based Budget plan,' 'ready-to-use budget table') and the zero-based budgeting methodology, which helps the agent understand the behavioral outcome beyond the annotations.

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 efficiently structured in three sentences: first explains what it creates, second describes the zero-based methodology, third provides usage guidance. Every sentence adds value without redundancy, and it's appropriately front-loaded with the core functionality.

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 tool with rich annotations (read-only, non-destructive, idempotent) and comprehensive schema coverage, the description provides good contextual completeness by explaining the output format ('ready-to-use budget table') and positioning among siblings. The main gap is lack of output schema, but the description compensates somewhat by describing the return value.

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?

With 100% schema description coverage, the schema already documents all 8 parameters thoroughly. The description doesn't add specific parameter semantics beyond what's in the schema, but it contextualizes them by mentioning they're used to create a 'personalized' plan based on 'income and life situation,' which aligns with the schema's purpose.

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 clearly states the tool creates a personalized Zero-Based Budget plan based on income and life situation, specifying it assigns every unit of income to categories so Income - Allocations = 0. It distinguishes from siblings by being the 'core tool' for building budgets, which differentiates it from analysis, audit, summary, or calculation tools.

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 explicitly states 'use it when someone wants to build a budget, allocate their income, or create a spending plan,' providing clear when-to-use guidance. While it doesn't mention specific alternatives, it positions this as the primary tool for budget creation among siblings focused on analysis, auditing, or calculations.

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