orca-orchestration

orca-orchestration is a skill for Claude Code, Codex from upex-galaxy/agentic-qa-boilerplate. It costs 424 tokens per session (9,338 once invoked), scanned A, original, MIT.

A workflow for coordinating several persistent coding-agent sessions from one lead session. Each worker owns a separate story, module, or failure group, and the work can run through the Orca runtime or be started manually in terminals.

In plain words
What is it for?
Use it to split work across agent sessions, coordinate a run, exchange status through a mailbox, and recover or steer an active group of workers.
Why use it?
Large tasks can exceed what one session can handle, while parallel work can conflict without clear ownership and communication. This provides a structure for assigning, tracking, interrupting, and resuming workers.

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

orca-orchestration scanned grade A 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 5d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- DO verify credentials on the worker's own screen before dispatching work to it. The native launch has no argv: every MCP server, on any harness, reads the worktree's own `.env` through the `.env` loader in the MCP conf

Orca Orchestration — One Conductor, a Fleet of Sessions

This skill is the transport layer for work that does not fit in one session. A conductor talks to the owner and coordinates workers; each worker is a persistent agent session that owns a scope from start to finish, reports through a mailbox, and can be interrupted, questioned and resumed. The fleet is all workers of one Run.

It is optional by construction. Everything here has a path that works with no runtime at all: the same launch lines, pasted into terminals by a human, and the same tokens and artifacts the workflow skills already write. What the runtime buys is the step a human would otherwise do with their hands, plus a mailbox instead of screen-scraping.

Read full SKILL.md when: starting a fleet cold, arbitrating a claim, choosing a topology, recovering a Run from a previous session, or writing an unattended automation.


When to use

  • The user asks to parallelize, orchestrate, or run "one session per story / module / failure cluster".
  • The user wants to talk to, steer, interrupt, question or close a session that is already running.
  • The user wants the state of a fleet, or to pick up a wave from a previous session.
  • A brief names this skill (WORKER mode).
  • An unattended routine has to dispatch work with nobody at the wheel.

When NOT to use

Situation Use instead
a read, a verification, a map — anything that fits in this turn one-shot subagents (AGENTS.md §3). This is most work
"hand this TASK to another agent and forget it" that is a HANDOFF, not orchestration: no Task, no Dispatch, no mailbox. Ask the binary for its orca-cli guide
"hand this whole SESSION to a fresh one, my context is full" ownership transfer of the session itself, same worktree, same harness
per-ticket manual QA /sprint-testing
writing test code /test-automation
branch / commit / push / PR mechanics, or a plain git worktree with no fleet /git-flow-master
one long task, one session, no siblings just do the task

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.
