Claude Code Skill

The included skill lets Claude Code call herd itself — checking what sessions are running, spawning parallel agents, forking conversations, and sending input to coordinate across tabs.

Install

Run these slash commands inside a Claude Code session:

❯ /plugin marketplace add generativereality/plugins
  ⎿  Successfully added marketplace: generativereality

❯ /plugin install agentherder@generativereality
  ⎿  ✓ Installed agentherder. Run /reload-plugins to activate.

❯ /reload-plugins
  ⎿  Reloaded: 1 plugin · 0 skills · 5 agents · 0 hooks · 0 plugin MCP servers · 0 plugin LSP servers

Note: These are Claude Code slash commands, not shell commands. Type them at the ❯ prompt inside a Claude Code session.

This installs both the herd CLI and the skill. Updates are delivered via the plugin — run /plugin update agentherder to get the latest.

What Claude can do with it

Check what's running:

herd sessions

Spawn a parallel session and send it a task:

herd new payments ~/Dev/myapp
herd send payments --file /tmp/task.txt
echo "implement the billing endpoint" | herd send payments

Fork its own session to try an alternative approach:

herd fork auth -n auth-v2

Monitor a sibling session without switching to it:

herd scrollback payments 100

Approve a tool call in another session:

herd send payments "yes\n"

How it works

The skill (SKILL.md) is loaded into Claude Code's context when placed in .claude/skills/herd/. It gives Claude:

• The full command reference
• Workflow patterns for common multi-session tasks
• Tab naming conventions
• Auto-install logic for the CLI itself
