Solve CAPTCHA

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

The description goes well beyond annotations by disclosing that success is not guaranteed, that the return message is identical for success and failure, that no click is attempted if no CAPTCHA is detected, and that page state or cookies may change. It also explains CDP stealth and shadow-DOM limitations. This is consistent with readOnlyHint=false and destructiveHint=false.

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 well-organized with a numbered workflow, provider list, limitation paragraph, and return note. However, the opening two sentences are somewhat redundant: both say the tool 'attempts' a CAPTCHA interaction. Slight trimming would make it tighter.

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 zero-parameter tool, the description supplies all essential context: target controls, mechanism, no-op behavior, success ambiguity, side effects, and post-inspection workflow. The return message caveat covers what the output schema would otherwise need to explain. Nothing critical is missing.

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?

There are zero parameters, so schema coverage is effectively 100% and the baseline is 4. The description adds that CAPTCHA coordinates are auto-detected and no user input is required. There is no parameter documentation gap to compensate for.

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 opens with a specific action and scope: 'Attempt a SeleniumBase CDP-based CAPTCHA interaction' and names concrete interaction types and providers. It also explains automatic coordinate detection, making the tool's role distinct from generic click_element or run_javascript. The purpose is 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 gives a clear workflow: inspect with get_content first, call solve_captcha, then verify with get_page_info, get_content, check_if_condition, or manage_cookies. It does not explicitly state when not to use the tool or name a non-CAPTCHA alternative, so it stops short of full when-not guidance.

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