What problem does it solve? Removing an installed agent team by hand risks deleting files the user edited or leaving orphaned configuration behind. This Skill reverses an Essential installation safely by consulting the recorded ownership manifest instead of guessing which files belong to the installer. ## Core Features & Use Cases - Ownership-based removal: Uses the .essential/ ownership record as the sole authority, removing only files whose content still matches the installed hash and preserving anything the user modified. - Harness-aware targeting: Supports claude, codex, and grok runtimes with correct default agent destinations, and detaches the Grok bootstrap attachment from the user AGENTS.md without touching surrounding text. - Idempotent and recoverable: Repeated runs are harmless, shared support files are retained while preserved agents need them, and unresolved entries are kept for a later retry. - Use Case: After evaluating the marketplace in a Grok environment, run the uninstall to remove the installed agent team and its startup guidance while keeping your custom rules and any agents you edited. ## Quick Start Ask the assistant to uninstall the Essential agent installation for the current harness, for example by saying "uninstall the Essential agents from my Grok setup and keep my edited files".
