Use when measuring, profiling, or comparing performance; when implementing or reviewing code on startup, interaction, render, scroll, event, polling, synchronization, list-processing, store-selector, cache, indexing, or high-volume data paths; when users report lag, freezes, jank, high CPU, memory growth, heavy network traffic, slow startup, or performance regressions; when writing motion, keyboard or focus handling for the iOS app; and before accepting memoization or caching as a fix for repeated work.

Rules for everything a person reads, from your own replies in a session to documentation, UI copy, PR and issue comments, release notes, and posts. Strips AI-generated patterns so the text reads like a person wrote it.

Prepare an approved ticket for human submission by updating durable knowledge, summarizing scope and verification, teaching material flows with progressive visuals, and providing the merge handoff. Use only after review approval. Unless codeHost.pullRequests is false, commit the approved work, push the ticket branch, and create or update the pull request. It never merges.

Analyze a user's Plannotator plan archive to extract denial patterns, feedback taxonomy, evolution over time, and actionable prompt improvements — then produce a polished HTML dashboard report. Falls back to Claude Code ExitPlanMode denial reasons when Plannotator data is unavailable.
