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

With no annotations, the description carries full behavioral burden. It mentions generating reports and artifacts but omits key operational traits: whether it requires network access, executes scripts in a browser, handles authentication, has rate limits, or what permissions are needed. For a tool that writes files to outputDir, these gaps are significant.

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 a single dense sentence that front-loads the core purpose and then lists secondary capabilities. It is information-packed but not repetitive; however, the long enumeration could be slightly streamlined without losing value.

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 complex tool with six parameters, no output schema, and no annotations, the description covers what the tool does and what artifacts it generates, but it lacks operational context such as environment requirements, failure modes, or security implications. It is sufficient to understand the tool's purpose but not fully complete for safe invocation.

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 description coverage is 100%, so the schema already documents all six parameters thoroughly. The description does not add meaning beyond what the schema provides for any parameter; it only reiterates high-level capabilities already implied by the parameter names.

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 uses a specific verb ('Profiles') and enumerates the exact resources (Canvas 2D, WebGL/GPU, AudioContext, etc.), plus additional actions like detection, entropy calculation, and report generation. This clearly distinguishes it from sibling tools such as web_decompile_shaders or web_recon_infrastructure.

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 implies the tool is for auditing client-side fingerprinting and anti-bot telemetry, but it never states when to use this tool versus alternatives or when NOT to use it. No explicit prerequisites or exclusions are given.

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