flare_get

Fetch web pages through FlareSolverr with HTTP GET to bypass Cloudflare and DDoS protection, returning page content, cookies, and headers after solving challenges.

Instructions

Make an HTTP GET request through FlareSolverr to bypass Cloudflare/DDoS protection. Returns the page content, cookies, and headers after the challenge is solved.

TDQS

A3.6/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It usefully discloses the return payload (page content, cookies, headers) and that the challenge is solved before returning, but omits the operational traits an agent would want: that this is slow/heavy, session reuse behavior, timeout implications, and rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, front-loading the core action (GET through FlareSolverr to bypass protection) followed by the return contract. No filler, every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an 11-parameter tool with no output schema and no annotations, the description compensates by summarizing the return shape (content, cookies, headers) and the challenge-solving behavior. It is largely complete, though silence on session/timeout behavior and performance characteristics leaves minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 91%, so the schema already documents nearly all 11 parameters (proxy, cookies, session, maxTimeout, disableMedia, etc.). The description adds no parameter-level detail beyond what the schema provides, making the baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource: an HTTP GET request via FlareSolverr, with the added purpose of bypassing Cloudflare/DDoS protection. The GET verb implicitly separates it from the flare_post sibling, but no sibling is named explicitly, so it falls just short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The bypass-Cloudflare framing implies when the tool is relevant, but there is no explicit when-to-use/when-not guidance and no routing to alternatives such as flare_post or the session tools. Usage is left to inference.

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