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

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes the tool's function and default behaviors (e.g., weekly digest with no params, default inclusion of expirations implied by parameters), but lacks details on permissions, rate limits, or error handling, which are important for a tool with multiple parameters.

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 front-loaded with the core purpose, followed by usage notes, in two efficient sentences with zero wasted words. Every sentence earns its place by adding actionable information.

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 complexity (6 parameters, no annotations, no output schema), the description is adequate but incomplete. It covers purpose and basic usage but lacks details on output format, error cases, or advanced behavioral traits, which are needed for full contextual understanding.

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 description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds minimal value by mentioning filtering by 'vendor, change type, or date range', which aligns with parameters but doesn't provide additional semantics beyond the schema. Baseline 3 is appropriate given high schema coverage.

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 ('track', 'returns') and resources ('developer tool pricing changes, upcoming expirations, and new deals'). It distinguishes from siblings by focusing on tracking changes rather than comparing vendors, planning stacks, or searching deals.

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 clear context for when to use the tool ('with no params, returns a weekly digest') and how to filter results. However, it does not explicitly state when not to use it or name specific alternatives among sibling tools, keeping it from a perfect score.

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