This skill solves the complex, time-consuming process of reverse-engineering PerimeterX (PX) SDK collector traffic to generate valid _px3 or _px2 cookies. Without this skill, developers must manually deobfuscate SDK code, locate cryptographic constants, decode binary OB responses, and reconstruct 200+ field payloads across multiple deployment tiers, often spending 6-12 hours per new site with no guarantee the generated cookie will pass backend trust validation.
Use the px-reverse skill to reverse-engineer a new PX-protected site by providing the target URL and capturing 6 batches of collector traffic via CDP, then run the bundled decode and diff scripts to build a working cookie generator.

To reverse-engineer PerimeterX cookies, capture 6 batches of collector POST traffic via Chrome CDP, then apply bundled algorithm modules to reconstruct payloads, decode OB responses, and generate valid _px3 or _px2 cookies for validated sites.
PerimeterX strict tier analysis uses field-by-field diff tools, cross-event consistency checkers, and a 4-way trust matrix to validate generated cookies against PX-gated endpoints, localizing whether failures stem from cookie content or transport/IP issues.
Yes, you can generate _px3 cookies for HUMAN Security protected sites across lenient, strict, and strict+ deployment tiers, specifically validated for platforms including iFood, Grubhub, Total Wine, and Academy.
To handle PerimeterX SDK upgrades, use grep-pattern-based location methods and a 27-entry OB handler shape-matching table to locate field semantics, avoiding full generator rewrites when SDK code changes occur.
PerimeterX cookie validation fails when 200+ field payloads are incorrectly reconstructed, requiring 6 batches of cold-visit samples and algorithm modules like payload XOR, HMAC-MD5 PC, and SID steganography to ensure accurate payload generation.
Yes, Chrome CDP capture is required to collect the 6 batches of cold-visit collector traffic samples needed to reconstruct payloads and validate generators against PX-gated endpoints.
