One rules file for all your parallel Claude Code sessions
When several Claude Code sessions work on one repo, each one re-learns your conventions from scratch. A short, shared CLAUDE.md keeps them consistent — here is what to put in it and what to leave out.
Port and database collisions when parallel AI agents run your app
Two Claude Code sessions both start the dev server on the same port, or both reset the same test database. How to give each parallel agent its own port, database and cache so their test runs stop interfering.
Give every AI coding agent a scope limit and a done condition
Why long-running Claude Code sessions drift, and a simple brief — allowed area, forbidden area, stop condition, and proof of done — that keeps parallel agents on task.
The five-line handoff note: ending a Claude Code session so the next one starts fast
A short, repeatable handoff note to write before you close a Claude Code session — what was done, what's in progress, what's next, and how to verify — so resuming tomorrow takes minutes instead of re-explaining.
When Two AI Coding Agents Edit the Same File
Practical steps for preventing and recovering from file collisions when several Claude Code sessions edit one repository — ownership boundaries, Git worktrees, and how to recover safely.
How to Bring Back Many Claude Code Sessions After a Reboot (macOS)
A crash or reboot shouldn't cost you an afternoon of re-launching AI coding sessions. Here's how to make many Claude Code sessions survivable on macOS — what to script, and where a purpose-built app removes the chore entirely.
Using Git Worktrees to Run Multiple AI Coding Agents Safely
Running several AI coding agents in the same repo invites collisions. Git worktrees give each agent its own checkout and branch, so parallel work stops stepping on itself. Here's the workflow.
How to split a backlog into tasks parallel AI agents won't fight over
Most parallel-agent pain is a decomposition problem wearing a tooling costume. Four rules for slicing work so six agents produce six mergeable branches instead of one merge-day disaster.
Which agent is waiting on you? Triaging a stalled fleet
The expensive failure in parallel AI coding isn't a wrong answer — it's an agent that asked a question forty minutes ago and has been idle ever since. Here's how to notice, and how to stop noticing manually.
The Hidden Cost of Context-Switching Between AI Coding Agents
Running several AI coding agents feels productive, but the real tax is context-switching — reloading which agent was doing what every time you look away. Here's how to cut that cost.
Sending one command to many AI agent sessions at once
When six agents all need the same instruction — pull main, run the tests, stop — typing it six times is where parallel work stops paying off. Here's how fan-out input works, and what you should never broadcast.
Session Naming Conventions for Running Many AI Coding Agents
When you run several Claude Code sessions at once, the first thing that breaks is knowing which is which. A simple naming and color scheme prevents the most expensive fleet mistake — acting on the wrong repo.
What's new in Agent Tile, September 2026
September brings workspace tabs, usage gauges, leader tile controls, full-screen updates, and a byte-checked ship gate to Agent Tile, with measured results.
Git worktrees for AI coding agents: one repo, many parallel branches
Two AI agents in one checkout will clobber each other. Git worktrees give every agent its own directory and branch, from a single repo — here's the setup.
The complete macOS setup for a fleet of Claude Code agents (2026)
A start-to-finish checklist for running 4–8 Claude Code sessions in parallel on a Mac — isolation with git worktrees, session identity, broadcast, crash recovery, and the settings that prevent the classic mistakes.
How to tell your Claude Code sessions apart (before you type into the wrong one)
Five Claude Code sessions, five identical terminal windows. Practical ways to label, color, and arrange parallel sessions on macOS so you never send an instruction to the wrong project.
tmux vs a GUI for parallel AI coding agents: an honest comparison
Running several Claude Code sessions at once? Here's where tmux genuinely wins, where a purpose-built GUI wins, and the three questions that decide it for your setup.
The 3-Agent Setup for Code Review: One Writes, One Reviews, One Watches
A durable pattern for AI-assisted code review: three parallel Claude Code sessions with clear roles. Writer, adversarial reviewer, and drift-watcher. When to use it and when not.
How to Recover Crashed Claude Code Sessions in Under 30 Seconds (2026)
When your terminal crashes with 6 Claude Code sessions running, recovery usually means starting from scratch. Here is the setup that restores all sessions in under 30 seconds.
Claude Code's agent view, and the two things it deliberately doesn't do
Claude Code now ships a built-in dashboard for background sessions. Here is what claude agents covers, where it stops, and how to tell which half of the job you actually have.
Do You Need a Tool to Run Multiple AI Agents, or Just Discipline?
Before buying anything to manage multiple AI coding agents, it's worth asking what a tool actually buys you over plain discipline. Here's an honest breakdown of where habits are enough and where a purpose-built layout pays off.
How many AI coding agents can you actually run at once?
The limit on parallel AI coding agents isn't CPU or RAM — it's how fast you can review their output. Here's how to find your real number.
Crash-proof your AI coding sessions: why session restore matters
Losing a fleet of AI coding sessions to a crash or restart wastes real context. Here's why session restore matters and how to keep your agents recoverable.
A workflow for reviewing AI-generated code across many agents
When several AI coding agents produce diffs at once, review becomes the bottleneck. Here's a workflow to review AI-generated code fast without missing things.
How to run multiple Claude Code sessions in parallel on macOS
A practical guide to running several Claude Code (and other AI coding) agents at once on macOS without losing track of which window is which.
