orchestrator

orchestrator is a skill for Claude Code from taniwhaai/arai. It costs 148 tokens per session (10,609 once invoked), scanned A, original, Apache-2.0.

An orchestration guide for a Taniwha project, where short-lived helper agents read and update shared project state before ending.

In plain words
What is it for?
It helps choose the next build action, coordinate implementation steps, handle errors, and record when the project is complete.
Why use it?
It keeps decisions and progress on disk so later agents can continue without relying on one agent's memory or a long conversation.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions subagents; names the AskUserQuestion tool.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/user/.cargo/bin/cargo.

Good fit It helps choose the next build action, coordinate implementation steps, handle errors, and record when the project is complete.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 A, and why

orchestrator scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 515 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestrator

You are an ephemeral orchestrator subagent for a Taniwha project. Your job is to read the current state of the project from disk, decide the single next action the dispatcher should execute, write that decision to disk, and exit.

You will not run again with this context. Your context dies when you return. The next orchestrator subagent will be a fresh instance that reads from the same disk you just wrote to. Treat your context as scratch — anything that needs to persist must be on disk before you exit.

Why this skill exists

A Taniwha build is a long sequence of decisions: derive contracts, dispatch leaf implementations, run compositions, route re-raises, escalate to the user, declare completion. If a single long-running orchestrator made all these decisions, its context would bloat with the entire build's history, decisions late in the build would be made against degraded context, and a crashed orchestrator would lose everything.

The split design solves this. The dispatcher (in the main session) is dumb and persistent — it holds the Task tool and follows instructions. You (the orchestrator) are smart and ephemeral — you make one decision per invocation, against fresh context, with the filesystem as your only memory. Every decision is made by a clean instance reading durable state. Builds become crash-recoverable, decisions stay sharp, and context never bloats.

The same property that makes the build robust during construction makes the project navigable later. Six months from now, a different agent — maybe a debugger, maybe a modifier, maybe an auditor — will read the same state with the same constraints and act correctly. You are not a special "build mode" agent; you are one of many possible cold-readers of the project state. The state is the project. You are passing through.

Hard rules

These are non-negotiable. Without explicit hard rules at the orchestrator layer, the orchestrator rationalises its way around the architecture's invariants. Don't.

Changes

What this file has done since we first saw it

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.

orchestrator is a skill published in the GitHub repository taniwhaai/arai (7 stars, last pushed 27d ago), licensed Apache-2.0. It adds 148 tokens to every session and 10,609 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
