Definition
The Comet Skill / CDP browser delegation pattern is a way to give a coding agent (Claude Code, Codex) deep research capability by connecting to your already-logged-in Perplexity Comet browser over Chrome DevTools Protocol, opening a clean Perplexity Deep Research tab, submitting a query, and returning the search URL — without paying the Perplexity API or sitting on the agent waiting tens of thousands of tokens.
In Depth
An r/codex post in May 2026 introduced the open-source Comet Skill (github.com/ammarshah1n/comet-skill). The mechanic: agent receives a research task → Comet Skill connects over CDP → opens a Perplexity tab → selects Deep Research → uploads files → submits → returns the /search/<id> URL. The agent does NOT block waiting; it gets a URL back fast and continues other work, then the user reviews the finished research thread when ready. The pattern is solo-developer friendly (uses your existing Pro subscription) but doesn't fit headless-server / multi-tenant production. For production, Scavio MCP fills the typed-JSON SERP + Reddit + YouTube lookup role; Comet Skill complements it as the deep-research delegation layer when the user pays for Perplexity Pro.
Example Usage
Solo developer using Claude Code daily attaches Comet Skill + Scavio MCP. Claude calls scavio.search for fast typed lookups during coding; for deep multi-step research it hands the task to comet_research, gets a /search/<id> URL back in seconds, keeps coding, reviews the Perplexity thread when needed. Cost: Perplexity Pro $20/mo + Scavio $30/mo, no API fees on Comet.
Platforms
Comet Skill / CDP Browser Delegation is relevant across the following platforms, all accessible through Scavio's unified API:
