You: (just open Claude Code)

Orra: Morning. Yesterday's first move was: pick back up on JWT refresh.
      Today's situation:
      • Due today: AUTH-142 (in_progress, worktree auth-refactor)
      • Ready to land: billing-fix — PR approved, mergeable
      • Needs attention: onboarding — blocked (claude attach abc1234f)
      Recommended first action: triage onboarding (30s), then JWT.
      What's your plan for today?

You: focus is JWT, ship by 4pm.

Orra: Got it. I'll align suggestions to that. Spawning a background
      agent to rebase the 2 stale worktrees while you work — they'll
      be ready when you come back to them.

Orra is the standing orchestrator — the directive/intelligence/memory layer that rides on Claude Code's Agents View. The Agents View tells you "row 3 is waiting." Orra reads what row 3 is waiting on, runs a directive to handle it, keeps the memory layer, and reports a condensed picture.

What it is

Orra is not a worktree manager or a process supervisor — Claude Code's Agents View handles that. Orra is the layer on top: morning briefing, a heartbeat-driven directive pack, the .orra/memory/ layer, PR shepherding, Linear deadline tracking, and per-worktree cost tracking. It runs as a persistent claude --bg background agent so the heartbeat never needs re-arming.

Requires Claude Code ≥ 2.1.x with the Agents View enabled.

Three capabilities:

• Awareness — orra_scan joins the daemon roster ($CLAUDE_CONFIG_DIR/jobs/)

with git worktree list, PR data, and custom providers. Classifies status (ready_to_land, needs_attention, in_progress, idle, stale) and pre-computes per-agent summaries so you never re-parse transcripts.

• Learning — a markdown memory layer under .orra/memory/. Daily notes, commitments,

per-worktree notes, and weekly retros persist across sessions. Directives like morning-briefing and shutdown-ritual maintain it for you.

• Coordination — orra_spawn wraps claude --bg; spawned sessions appear in

claude agents. orra_kill calls claude stop/claude rm. Blocked agents surface as needs_attention with a claude attach hint.

Install

Option A — as a Claude Code plugin (recommended)

# From a local clone (until the plugin marketplace is available)
claude --plugin-dir /path/to/orra-mcp

This registers the orchestrator agent, the /orra command, and the orra-mcp MCP server in one step.

Option B — as a standalone MCP server

claude mcp add orra -- npx orra-mcp

Quick start

1. Scaffold the project

In any Claude session, run:

> "run orra_setup"

This creates .orra/config.json, installs the orchestrator agent at .claude/agents/orchestrator.md, merges the Orra MCP server entry into .mcp.json, writes a sample WorktreeCreate hook to .claude/hooks/worktree-create.sh, and scaffolds the memory layer. Idempotent.

2. Install the directive pack

> "install all orra directives"

Copies the full directive library (10 directives) into .orra/directives/. Each declares its own "lane" so they compose without conflict.

3. Start the orchestrator

orra
# or: claude --bg --agent orchestrator --name orra

The orra bin ensures the orchestrator is running as a named background agent. To talk to it: claude attach orra.

A day with Orra

Morning — awareness

The morning-briefing directive fires automatically on session start. It calls orra_scan, reads yesterday's daily note, checks commitments.md, and composes the picture.

Side tasks — delegation

While you work, auto-remediator notices stale worktrees and spawns bg agents via orra_spawn (claude --bg) to rebase them. They appear in claude agents. Results show up in the next orra_scan. You never had to stop.

End of day — memory

shutdown-ritual writes .orra/memory/daily/.md with shipped/open/first-move sections. Tomorrow's morning-briefing reads this and starts you exactly where you left off.

Writing your own directive

Directives are markdown files in .orra/directives/ that the orchestrator reads each tick.

### Heartbeat invocation
(what to check each tick)

YAML frontmatter is optional. session_start: auto + once_per: day + resets_at: "HH:MM" opts into auto-run at session start. See [docs/directives.md](docs/directives.md).

Tools (11)

| Tool | Purpose | |---|---| | orra_scan | Scan all worktrees. Daemon roster ⨝ git ⨝ PR ⨝ providers → classified view with pre-computed summaries. | | orra_inspect | Deep dive on one worktree — commit log, markers, conflict prediction, transcript tail. | | orra_kill | Stop (claude stop) or remove (claude rm) a bg agent + optional PR cleanup. | | orra_rebase | Rebase a worktree branch onto latest main (spawns a bg agent). | | orra_setup | Scaffold .orra/ + install orchestrator agent + WorktreeCreate hook. Idempotent. | | orra_directive | Manage directives (add, list, remove, install shipped ones). | | orra_spawn | Spawn a bg agent via claude --bg. Sessions visible in claude agents. | | orra_resume | Restore session state after /compact. | | orra_tick | Heartbeat dispatcher — runs due directives. | | orra_checkpoint | Write session state to disk for compact survival. | | orra_cache_write | Write a subagent digest into the session cache. |
