parallel-execution

parallel-execution is a skill for Claude Code, Codex from omagents/omagents. It costs 28 tokens per session (329 once invoked), scanned A, original, MIT.

A background-work workflow that lets an orchestrator coding agent split independent tasks and run them at the same time. It also provides a way to view or cancel those tasks.

In plain words
What is it for?
Use it for parallel research, code inspection, or other independent subtasks. Check progress with /ps or cancel a running task when needed.
Why use it?
It reduces waiting when several parts of a request can be handled independently. A shared job board keeps track of work that is still running or has finished.

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

parallel-execution 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 2mo 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.

What it actually says

Parallel Execution

The orchestrator agent is the default agent. It automatically decomposes tasks into parallel background subagents when beneficial.

How It Works

You don't need to do anything special. When you ask the orchestrator to do something that can be parallelized, it will:

  1. Decompose your request into independent subtasks
  2. Launch each as a background task via task(background: true)
  3. Continue working on other things while they run
  4. Synthesize results when all tasks complete

Checking Status

Type /ps to see all background tasks:

/ps

Cancelling Tasks

Tell the orchestrator to cancel a task, or it will use the cancel_task tool:

cancel the research task

Background Job Board

The plugin automatically injects a "Background Job Board" summary into the orchestrator's context. This includes running tasks and completed (unreconciled) tasks with their results. The orchestrator acknowledges completed tasks before responding.

Tips

  • Background subagents are auto-enabled by the plugin.
  • The orchestrator decides when to parallelize - you just talk naturally.
  • For dependent tasks, the orchestrator launches the first, continues other work, and launches the dependent task when results arrive.
  • Don't ask the orchestrator to "wait" for background tasks - it knows when they complete.

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.
