mstar-use-cli

Use when a Morning Star agent must choose, run, or interpret mstar-harness / mstar CLI commands — picking the command family for a task (plan row, lifecycle close, register write, report landing, worktree and lease checks, path resolution), satisfying the preconditions a family needs (harness root, control root, neutral cwd, session envelope, version tokens), reading exit codes 0 / 1 / 2 and stable refusal codes, or running the versioned read-modify-write handshake. Also load it when a topical skill's engine-check callout points at the CLI, or when a command refused and the cause looks like a missing precondition. Flags and option wording are never restated here — the CLI help owns them.
