# cmux Diagnostics Collect and interpret support-safe cmux diagnostics for end users. Default to read-only checks. Never dump hook config files, session stores, prompt logs, tokens, or environment secrets. ## Quick report Run the bundled read-only script first, from whichever install path exists: ```bash skills/cmux-diagnostics/scripts/cmux-diagnostics # cmux checkout ~/.agents/skills/cmux-diagnostics/scripts/cmux-diagnostics # installed skill ~/.codex/skills/cmux-diagnostics/scripts/cmux-diagnostics # Codex-only skills.sh install ``` Add `--include-context` only when workspace names, cwd paths, and current cmux identifiers are relevant to the reported issue. ## What to check 1. **CLI and socket health**: `command -v cmux`, `cmux ping`, `cmux capabilities --json`. If socket commands fail, check whether the agent is running inside a cmux terminal and whether socket automation is enabled. 2. **Settings health**: `cmux-settings validate` and `cmux-settings get terminal.autoResumeAgentSessions` (from `~/.agents/skills/cmux-settings/scripts/`, or `~/.codex/skills/...` for a `skills.sh` install). When `terminal.autoResumeAgentSessions` is false, cmux restores panes but does not resume saved agent sessions. 3. **Hook installation**: `cmux hooks setup --agent codex`, `--agent opencode`, or bare `cmux hooks setup` (installs supported agents found on PATH, skips missing ones). Run install or uninstall commands only after the user agrees. 4. **Session restore eviden
