Paul O'Reilly 916acd39e1 docs(memory): add /spawn-session skill reference
Per the skill convention, document /spawn-session (purpose, usage, how it
wraps claude-tmux, gotchas) and index it in MEMORY.md.

/spawn-session

Purpose

Spawn a new, separate Claude Code session inside a detached tmux session with Remote Control enabled, in a project's directory, named after the project (e.g. "Agent Runtimes", auto-incrementing to "Agent Runtimes #2"). Lets the user start a session for another project that persists on the host and is reachable later via tmux attach (over VPN) or driveable from the Claude app.

Usage

  • /spawn-session <project> — spawn for a named project folder
  • /spawn-session <project> --mode <mode> — override engagement mode
  • /spawn-session <project> --attach — attach after spawning
  • /spawn-session — lists projects and asks which one

How it works

Thin wrapper over the claude-tmux script (in small-scripts, symlinked to ~/sbin). The skill only resolves the project name from $ARGUMENTS (or asks) and shells out to claude-tmux <project> [flags]. All real logic — folder resolution, mode selection (profile last-mode unless --mode), Title-Casing, #N auto-increment, tmux creation, and launching claude --remote-control via claude-profile — lives in the script.

Gotchas

  • Separate process, not a sub-agent. The spawned session does not share the current conversation's context. It's a full interactive Claude Code session the user drives.
  • Remote Control only registers once claude is running. The script guarantees this by passing the engagement mode explicitly so claude-profile never stalls at its interactive picker. Don't "fix" the skill to omit the mode.
  • Default profile is oreillyit-anthropic. Only override with --profile on request.
  • Concurrent same-profile sessions race on the shared active-mode.env, but each session's cwd takes precedence for project auto-selection, so the right project is picked.
  • Spec + tests: small-scripts/specs/claude-tmux.spec.md, tests/test-claude-tmux.sh.
