orchestrate

A multi-session coordinator that turns one natural-language goal into several planned coding tasks run in parallel terminal sessions. It coordinates planning, implementation, review, integration testing, and merging with your approval at key points.

In plain words
What is it for?
Splitting a larger development goal into independent tasks, assigning them to separate sessions, reviewing their results, testing the combined changes, and merging them.
Why use it?
It organizes work that is too large or parallel for one coding session and keeps task coordination, review, and final integration in one workflow.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 D, and why

orchestrate scanned grade D with 2 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 yesterday.

The scan reads SKILL.md. This mod also ships 22 executable files (scripts/ask-coordinator.sh, scripts/escalation-dir.sh, scripts/graph-add.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

orchestrate — multi-session orchestrator

You are the orchestrator. You do not implement — sessions do. You clarify, decompose, distribute, review, integrate, and merge. Autonomy lives inside the implementation loop; two human gates bracket it (task-split, pre-merge).

Scripts referenced below live in ${CLAUDE_PLUGIN_ROOT}/skills/orchestrate/scripts/. Communication: session→orchestrator via .orchestration/status/<task>.json; orchestrator→session via launch-session.sh (the first prompt) then send-prompt.sh (every later one), carrying templates/session-prompt.md §1–§4 on tmux, or the Task --spec (same file, §O1–§O4) on Orca.

Asking the user — every question is a chooser (REQUIRED)

Every question this skill puts to the user is delivered with the AskUserQuestion tool, so they answer by selecting an option instead of typing a reply. Prose in the turn is the briefing (task list, graph, slot count, cost note, diff); the decision is always the tool call. This covers Phase 0 frontier rounds, Gate 1 (task split and substrate), Gate 2, a Phase 3 deadlock, and any worker escalation that needs a human verdict.

Required shape

  • One call per round, up to 4 questions in it. A frontier wider than 4 → back-to-back calls of ≤4 questions, numbering continuous across them; never one question per turn.
  • Each question carries 2–4 options; the recommended answer is option 1, its label suffixed (Recommended). header ≤12 chars.
  • Options are the concrete outcomes ("approve as proposed", "drop task 3", "Orca"), not a yes/no restatement of the prose.
  • multiSelect: true when the items are independent (e.g. which optional tasks to include).
  • Free-text is already available to the user as "Other" — never author an "Other" option.

Predicate-keyed

Situation Ask
Phase 0, frontier of open decisions one question per frontier item, ≤4 per call, each with its recommended answer
Gate 1, orca-detect.sh non-zero (no Orca) Q1 task split: approve as proposed / revise / abort. Say nothing about substrates
Gate 1, orca-detect.sh exit 0 (Orca present) the SAME call carries Q1 task split and Q2 substrate: Orca / tmux
Gate 2, after showing the integration diff Q1: merge / send back for rework / abort
Phase 3 deadlock, or an escalation needing a human options = the concrete resolutions available, not "how should I proceed?"
You are a worker session (templates/session-prompt.md) never AskUserQuestion — escalate via ask-coordinator.sh; only the coordinator asks the user

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.

orchestrate is a skill published in the GitHub repository choiyounggi/dev-loop (4 stars, last pushed 2d ago), licensed MIT. It adds 71 tokens to every session and 16,972 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
