Documentation

README

Excerpt

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:

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.

This is the opening of the README. Read the full README on GitHub.
