Get BriefKit Information

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

Annotations already indicate safe/read-only. Description adds return value details (contents, pricing, prompt reduction stats) which is useful context beyond 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?

Three succinct sentences: purpose, usage trigger, return summary. No wasted words, front-loaded.

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?

No output schema but description enumerates exactly what is returned (pack contents, pricing, results). Rich annotations complement perfectly. Complete for a simple info tool.

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?

No parameters; schema coverage is trivially 100%. Baseline for 0 params is 4. Description does not need to add parameter info.

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?

Clearly states 'Get information about BriefKit' with detailed specifics (what's in the pack, pricing, integration with AI tools). Distinguishes from siblings that generate specific outputs.

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?

Explicitly says 'Use this when someone asks about BriefKit, SaaS specification tools, or how to reduce AI build tool iterations.' Could add when to avoid (e.g., for generating specific files).

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