Parallel Claude Code Session Coordination
Coordinate Claude Code tabs, Git worktrees, and SSH sessions without conflicting edits, lost context, or unsafe handoffs.
Before & after
Same prompt, same agent — the only difference is the skill.
Running multiple Claude Code sessions is definitely possible and can boost your productivity. The key is keeping each context focused so you don't get confused about which session is doing what. You could use terminal tabs and label them clearly — maybe one for planning mode, one for active development, one for a side project. You'll want to monitor your token usage across sessions since context windows can fill up fast. I'd suggest using /context or /compact commands to audit your session sizes periodically. Slack notifications when a session completes can help you juggle between them. What kind of work are you trying to parallelize?
MULTI-INSTANCE TERMINAL WORKFLOW STEP 1: ITERM SETUP Create three named panes: • Tab 1 label: plan-local • Tab 2 label: execute-local • Tab 3 label: experiment KEYBINDINGS: Cmd+] = next tab (switch focus) Cmd+[ = prev tab Shift+Tab in any pane = toggle plan mode on that session STEP 2: WORKFLOW PATTERN Tab 1 (plan mode): /ar:plan "design the refactor" Tab 2 (execute mode): active coding; run tests; monitor logs Tab 3 (experiment): try risky changes; prototype; keep isolated STEP 3: CONTEXT HYGIENE Before switching tabs: run /context audit to spot token bloat Monthly: /compact to trim old transcripts from memory When stuck: context shift — ask a different session for a fresh perspective STEP 4: NOTIFICATIONS enable notifications for finished runs in ~/.claude/settings.json: "notification_event": "on_completion" EXAMPLE SESSION: Tab 1 drafts a feature spec while Tab 2 refactors old code and Tab 3 experiments with a risky algorithm. Switch focus with Cmd+], keep each session under 20k tokens.
About this skill
Three Claude Code tabs can mean three useful workstreams, or three agents editing the same checkout while you lose track of which terminal is production. This workflow makes each session's task, workspace, authority, and next checkpoint visible so parallel work stays manageable.
What it does
- Separates independent tasks from work that must run in sequence.
- Assigns each editing session its own Git worktree and branch, with explicit ownership of shared resources.
- Defines iTerm tab labels that identify the task, role, and local or remote environment.
- Produces bounded planning, execution, and review prompts with concrete stop conditions.
- Preserves decisions and unfinished work across context compaction and session handoffs.
- Checks completion evidence and orders integration without confusing local commits with deployed changes.
What you get
A right-sized terminal layout, session assignments, ready-to-paste prompts, and a checkpoint schedule. When useful, you also get inline worktree setup commands and a concise status board showing dependencies, blockers, and completion evidence.
Best for
Developers running multiple Claude Code sessions in iTerm, especially when local development, planning, code review, and remote SSH work overlap.

name: parallel-claude-code-session-coordination
description: >-
Coordinate concurrent Claude Code terminal sessions by separating tasks, isolating workspaces, assigning shared-resource ownership, and enforcing verifiable handoffs. Use when the user says "run several Claude Code tabs", "help me juggle these terminals", "plan in one tab and build in another", "my agents keep overwriting each other's changes", or "split these tasks across sessions".
