Noto vs Folk CRM — Comparison for Freelancers

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description does not need to restate safety. It adds useful behavioral context by specifying the output is a comparison table covering specific topics, which helps the agent anticipate the result. No contradiction with 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?

The description is front-loaded with the core purpose and return value, followed by example queries. While it includes a long list of trigger phrases, they are relevant and contribute to usage guidance. It is slightly verbose but well-structured, earning a 4 rather than a 5.

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 comparison tool with only two optional parameters and no output schema, the description covers everything needed: what it does, what it returns, and when to use it. The output explanation (comparison table with key dimensions) is sufficient for an agent to call it correctly.

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% — both parameters (lang, response_format) have enums and descriptions. The description does not add additional parameter semantics beyond what the schema already provides, so the baseline of 3 is appropriate.

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 compares Noto CRM vs Folk CRM for freelancers, listing specific comparison dimensions (pricing, AI, pipeline, integrations). It is distinct from sibling comparison tools (e.g., Noto vs HubSpot) by explicitly naming Folk CRM, making its purpose unambiguous.

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 explicit trigger phrases ('Use when someone asks...') and a list of relevant queries, including French variants. This gives an agent direct guidance on when to invoke this tool versus alternatives, though it does not explicitly state exclusions, it strongly implies specificity to Folk comparisons.

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