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

With no annotations, the description carries the burden. It discloses a behavioral requirement (version must be provided) that goes beyond the schema, but it does not explain return format, error handling, or what happens if an invalid version is given. The typo-ridden version sentence adds ambiguity, leaving some behavioral aspects unclear.

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 reasonably sized and front-loaded with purpose, but it contains several typos ('libray', 'usally', 'can t fine') and a clunky version instruction that could be condensed. The message is clear but not polished, and each sentence does not earn its place efficiently.

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 simple search tool with well-documented parameters, the description provides adequate context for use, but it omits details about output format and the apparent contradiction between 'must provide a version' and the schema marking version as optional. This makes the description merely sufficient, not complete.

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?

Schema coverage is 100%, so baseline is 3. The description adds minor value by suggesting the version can be found in package.json, but it redundantly reiterates the schema's 'use latest' tip. Overall, it does not significantly enrich the parameter meanings beyond what the schema already provides.

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 explicitly states the tool 'Search Bryntum product documentation for technical information' and lists concrete use cases (API references, configuration options, examples, best practices) and product names. This clearly identifies the tool's purpose and resource, making it distinguishable even without siblings.

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 tells the agent when to use it ('Use this to find...') and provides a critical usage instruction: a version must be provided, with guidance on locating it in package.json and falling back to 'latest'. It does not mention alternatives because none exist, but the guidance is practical and actionable.

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