This skill activates for web scraping and Actor development. It proactively discovers APIs via traffic interception, recommends optimal strategy (traffic interception/sitemap/API/DOM scraping/hybrid), and implements iteratively. For production, it guides TypeScript Actor creation via Apify CLI.

Trace native execution on Android with Frida Stalker (Frida 17+): call summaries, event parsing, transforms, and performance-safe start/stop patterns.

Enforce safe Frida 17 MCP operations with strict phase gating. Use when attaching/spawning sessions, writing or loading scripts, applying Java/native hooks, troubleshooting instrumentation failures, or interpreting Frida MCP output. Require docs-first usage and run the mandatory workflow: Idea -> Scripting -> Execution -> Notes.

Use codex/codex-reply as a persistent second-engineer thread for non-trivial uncertainty — design choices, risky implementation decisions, debugging when stuck, review, spec ambiguity, needing a current/authoritative web_search, or any point where you'd otherwise guess. Keep one thread and iterate; don't treat the first answer as gospel.
