Session Transfer

Persist substantial work as an immutable, indexed handoff so a later session — or a different coding agent — can continue without reconstructing chat or terminal history.

Mode Selection

CREATE — save state, pause, context is getting full, /goal is closing, or an automatic trigger fires.

RESUME — continue previous work, load the latest session, or resume unfinished work on a topic.

Do not treat this skill as Codex-only. Detect the active runtime, then write under that agent’s directory.

Agent Detection

Before CREATE or RESUME, detect the active runtime. Do not pick Codex, Claude Code, or OpenCode just because .codex, .claude, or .opencode already exist (a repo may contain all three).
