What problem does it solve? Installing or reconfiguring the ECC plugin differs across AI coding harnesses, and guessing at scopes, hook profiles, or install commands leads to broken or duplicated setups. This Skill runs a guided, non-interactive configuration flow that respects each harness's real capabilities. ## Core Features & Use Cases - Harness-aware routing: Detects whether you are in Claude Code, Codex, or Kimi and applies only the options that harness actually supports. - Claude Code wizard: Inventories existing installs, collects exactly one scope (user, project, local) and one hook mode (off, minimal, standard, strict), previews with a dry run, confirms once, applies, and verifies the result. - Codex and Kimi paths: Uses Codex's native plugin lifecycle with marketplace refresh, or installs the project surface under ./.kimi-code without claiming unsupported hook profiles. - Use Case: You already have ECC installed at user scope in Claude Code and want to migrate it to project scope with strict hooks. The Skill detects the existing install, plans a scope migration with --move-scope, confirms once, applies, and verifies exactly one enabled ecc@ecc entry. ## Quick Start Ask the assistant to configure or update the ECC plugin for the current harness, choosing an install scope and hook mode if you are in Claude Code.
