Claude-skill-registry forky

Fork Claude sessions to handle side tasks in parallel. Use when the user wants to spawn a parallel Claude session, delegate a task to a background agent, monitor forked sessions, or when they mention "forky", "fork", "spawn", or "parallel task".

Forky - Parallel Claude Session Manager

Forky lets you spawn parallel Claude sessions to handle side tasks without interrupting your main workflow.

CRITICAL: Never Wait for Forks

Forks are fire-and-forget. After spawning, IMMEDIATELY continue with the next task. NEVER:

  • Say "I'll wait for the fork to complete"
  • Poll the fork status
  • Defer work pending fork completion

Forks notify you when done. Just spawn and move on.

Spawning a Fork

ALWAYS run forky spawn as a background shell operation. This ensures you don't block waiting for the spawn to complete.

# Use run_in_background=true with the Bash tool
~/bin/forky spawn "your task description here"

The binary is at

~/bin/forky
(NOT ~/.forky/bin/).

Model Selection

Always use Opus (the default). Do NOT use

-m haiku
or
-m sonnet
without asking the user first.

When to Fork

Good:

  • Code review while continuing development
  • Research while implementing
  • Test generation for code you just wrote
  • Documentation tasks
  • Any independent background work

Avoid:

  • Tasks requiring immediate user input
  • Modifying same files (use
    --worktree
    if needed)
  • Very short tasks (overhead > benefit)

Monitoring

~/bin/forky serve              # Start observability UI
~/bin/forky list forks         # List all forks
~/bin/forky messages <id>      # View fork messages

For Forked Agents

If you ARE a fork (check your callback instruction), call done when finished:

~/bin/forky done <your-fork-id> "summary of what was accomplished"
