detect_anti_bot

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

The word 'heuristic' usefully signals non-deterministic, inference-based results, and the vendor list clarifies detection scope. However, with no annotations provided, the description carries the full transparency burden and does not disclose return semantics (vendor name vs. null), whether analysis is passive, or failure behavior.

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?

A single 15-word sentence with zero filler. The scoping phrase 'on current page' is front-loaded, and the vendor examples are packed efficiently into the trailing parenthetical.

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?

Adequate for invocation — an agent knows there are no arguments and what the tool checks. But with no output schema and no annotations, the missing return-value semantics leaves the agent unable to interpret the result or act on it confidently.

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 tool takes zero parameters and schema coverage is 100%, so there is nothing for the description to add about inputs. The baseline 4 for zero-parameter tools applies; no param documentation gap exists.

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 states a specific action — 'detection of anti-bot vendor' — on a specific resource, 'current page', and names concrete target vendors (Cloudflare, DataDome, Akamai, PerimeterX, Imperva). This distinguishes it from siblings like detect_content_pattern and fingerprint_audit without needing to inspect their schemas.

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?

No guidance on when to use this tool versus alternatives. It does not mention, for example, using it before choosing click_turnstile or to diagnose blocked navigation, nor does it name any sibling as a fallback or exclusion. An agent must infer the use case entirely.

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