tapac_find_contacts

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

While no annotations are provided, the description adds significant context by specifying that contacts are returned as structured data with fields like name, title, company, email, source, and verification status. It also discloses that contacts are verified, which is a behavioral trait. However, it does not mention authentication needs, rate limits, or what happens when no contacts are found—minor gaps that prevent a top score.

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 succinct and well-structured, with a concise opening sentence followed by a bulleted list of criteria to ask for. Every sentence provides essential information without repetition or fluff. The structure is front-loaded with the main purpose, then details, making it easy for an AI agent to parse quickly.

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?

Given the tool's moderate complexity with 6 parameters, no required fields, and no annotations, the description covers the critical aspects: purpose, required user input, parameter semantics, and return structure. The presence of an output schema partially reduces the need to describe return values further. However, a note on error handling or empty results would enhance completeness for the agent, preventing it from being a 5.

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?

The description adds substantial meaning beyond the input schema by defining each parameter with concrete examples (e.g., industry 'SaaS', location 'US'), which compensates for the 0% schema description coverage. For the limit parameter with default 10, it clarifies the purpose. This goes well beyond the bare schema definitions, making the parameters actionable for the agent.

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's purpose: 'Find and verify B2B business contacts in real time.' The verb 'find and verify' combined with the resource 'B2B business contacts' and modifier 'in real time' makes the action explicit. It also distinguishes itself from the sibling tool 'tapac_status' by focusing on contact discovery rather than status checking.

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 usage guidelines by instructing the user to ask for specific criteria before calling the tool, listing each parameter with examples (e.g., industry 'SaaS', job_titles '[VP Sales, CTO, ...]'). This guidance clearly tells the agent when to use the tool—when it needs to collect these details from the user—and implicitly distinguishes it from the sibling tool 'tapac_status' which likely handles status queries.

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