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

With no annotations, the description carries full burden. It discloses that the tool reads 53 guides and returns specific outputs, and mentions 'no-card trial' as a behavioral nuance. However, it does not disclose whether the operation is read-only, any permissions, or error behavior. It adds some value but could be richer.

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?

Single sentence, front-loaded with the primary action, no wasted words, and includes all key information in a compact structure.

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 single-parameter lookup tool with no output schema, the description explains the matching logic and output types. It could mention what 'canonical guide paths' refers to or provide an example, but overall it is sufficiently complete for the tool's complexity.

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 a baseline of 3 is appropriate. The description adds minimal extra meaning, restating stack types but not providing format examples or additional semantic detail beyond the schema.

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 action ('Match an automation stack'), the resource ('53 published LeadProof platform guides'), and the specific outputs ('strongest canonical guide paths, no-card trial, and concise implementation steps'). This distinguishes it from siblings by focusing on integration instruction matching.

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 usage when a user has a stack and needs integration instructions, but it does not explicitly state when to use this tool over siblings like get_leadproof_trial or evaluate_leadproof_fit. No exclusions or alternatives are mentioned.

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