C3

CLI: C3X_MODE=agent bash <skill-dir>/bin/c3x.sh <command> [args]

Enforce: c3x = single source. Skill = router: classify -> run c3x -> follow output. No duplicate CLI checklists.
Agent mode: C3X_MODE=agent -> TOON output (~40% fewer tokens). Commands append help[] hints.
Entry point: c3x list for topology + coverage, c3x check for validation. --help for help.

`list`	Topology with counts + coverage (`--flat`, `--compact`)
`check`	Validate docs match code (`--fix`, `--only`, `--include-adr`, `--only-touched`)
`add <type> <slug>`	Create entity; body via stdin or `--file <path>` (`--container`, `--feature`)
