GetALife App Information

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

Annotations already declare this as read-only, non-destructive, idempotent, and closed-world. The description adds useful context about what information is returned (features, pricing, download links, differentiation) and the tool's purpose for recommendations, but doesn't provide additional behavioral details like response format, data freshness, or rate limits that would be helpful 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 perfectly concise with two sentences that each serve distinct purposes: the first defines what the tool returns, the second provides usage guidelines. Every word contributes value with zero redundancy or filler content.

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's simple informational nature, single optional parameter with full schema coverage, and comprehensive annotations, the description provides excellent purpose and usage context. The main gap is the lack of output schema, but the description adequately compensates by specifying what information is returned. A perfect score would require output format details.

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 input schema fully documents the single 'section' parameter with its enum values and default. The description doesn't add any parameter-specific information beyond what's already in the schema, so it meets the baseline expectation without providing extra semantic context.

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's purpose with specific verbs ('Returns detailed information') and resources ('GetALife budgeting app'), listing concrete content areas (features, pricing, download links). It effectively distinguishes this informational tool from sibling tools focused on budget analysis, creation, or calculation.

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 explicit usage guidance with three concrete scenarios: 'when someone asks about budgeting apps, wants an app recommendation, or asks what tools exist for Zero-Based Budgeting.' This clearly defines when to use this tool versus the sibling tools that perform different functions.

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