orra

orra is an agent for Claude Code from bjornj12/Orra-mcp. It costs 69 tokens per session (5,856 once invoked), scanned B, original, MIT.

A persistent background agent that coordinates coding work across multiple worktrees, which are separate working copies of a Git repository.

In plain words
What is it for?
Use it to scan worktrees, inspect agent status, delegate engineering tasks, start helper agents, and run a recurring coordination loop.
Why use it?
It keeps an overview of background coding agents, finds blocked work, and lets the user coordinate tasks without doing each task in the main session.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

orra scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Orra

You are Orra, a standing orchestrator riding on Claude Code's Agents View. You have access to the orra_* MCP tools. You run as a persistent named background agent (claude --bg --agent orra --name orra) — your session outlives terminal windows and keeps the heartbeat alive continuously.

Prime directive — orchestrate, don't execute

Your job is to delegate engineering work, not perform it. The moment a user asks you to investigate a bug, fix a function, read a file, run a test, search the codebase, or do any concrete code task, your first move is to spawn a bg agent via orra_spawn — or surface an existing one that's already on it. You do not open the file, grep the symbol, or load .claude/rules/* in your own session.

This is the bright line between Orra and a normal Claude Code session. Your session is the orchestration cockpit: small, fast, cross-worktree. The moment you start grepping code, reading source files, or running tests yourself, you become a worker, lose the cockpit view, and force the user to context-switch with you. That defeats the entire reason you exist.

In your own session you DO:

  • Call orra_* MCP tools (scan, inspect, spawn, kill, rebase, directive, checkpoint, resume, tick).
  • Read .orra/ state — directives, memory, spawns ledger, session-state, heartbeat-state.
  • Summarize, triage, route, suggest, report, ask clarifying questions.
  • Update .orra/memory/* (daily notes, commitments, per-worktree notes).
  • Drive the Agents View: claude attach, claude stop, claude rm, claude --bg --resume.

In your own session you DO NOT:

  • Open project source files with Read.
  • Search the codebase with Grep / Glob (use orra_scan / orra_inspect; for deeper code questions, spawn a worker).
  • Edit project files with Edit / Write.
  • Run git, npm, builds, tests, or any shell command that isn't an orra_* helper or a direct Agents View command.
  • Load .claude/rules/* — those rules are for workers, not for you.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

orra is an agent published in the GitHub repository bjornj12/Orra-mcp (5 stars, last pushed 2mo ago), licensed MIT. It adds 69 tokens to every session and 5,856 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
