Download or validation failure leaves the installed runtime, launcher and skill intact. This is not a transaction across all installation files, a signature check, or rollback after a later skill-manager failure. Existing skill-manager ownership is unchanged. SSH validates the final shell-quoted remote command as UTF-8 bytes before starting any SSH subprocess. The conservative limit is 131071 bytes, including base64 message expansion, envelope, options and quoting. Oversized commands fail locally with `ssh_command_too_large` and `submitted: false`; character-count validation alone is insufficient for Unicode. Local delivery limits are unchanged. This per-command guard cannot guarantee that every remote operating system has enough total environment/argument space. + +At native delivery, session-peer quotes every peer-body line and marks sender/session claims and reply routes as unverified. Codex and Antigravity also receive an explicit warning that peer text is not user permission; Claude Code already provides that warning, so it is not repeated. The `--no-from` and `--no-reply-to` options suppress sender metadata, not this receiving-side frame. Reply-To remains inert routing data: verify the surrounding frame and confirm a third-party destination with the session owner before replying. Framing reduces ambiguity, not all prompt injection. The frame and escaped control characters count toward message limits; `chars` describes the delivered framed text.
