Create a detailed execution plan/spec/PRD for implementing features or refactors in a codebase, designed around the program's entrypoints, the doors that carry domain intent, by leveraging existing research in the codebase.
Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells,…
Delegate work to builtin or custom subagents with single-agent, chain, parallel, async, forked-context, and intercom-coordinated workflows. Use for parallel codebase discovery, debug-and-fix, refinement, and multi-step tasks where a single parent agent stays…
Control tmux-compatible sessions/windows/panes for interactive CLIs: list, capture output, send keys, paste text, monitor prompts.
Document codebase as-is with research directory for historical context.
Automate browser interactions, test web pages and work with Playwright tests.
Streamline session-to-session coordination with the intercom extension. Send messages, delegate tasks, and coordinate work across multiple pi sessions on the same machine. Use for planner-worker workflows, cross-session context sharing, and real-time…
Create, improve, or optimize prompts using best practices.
