parallel-run

parallel-run is a skill for Claude Code from jpoutrin/product-forge. It costs 13 tokens per session (1,462 once invoked), scanned A, original, MIT.

A command for running development tasks in parallel through separate Git worktrees. It validates the task directory, starts the assigned agents, monitors their work, and reports the results.

In plain words
What is it for?
Use it to validate a parallel-task directory, execute its agent tasks, or view the current execution status.
Why use it?
It coordinates multiple coding tasks while keeping their file changes separated and checking that the setup is usable first.

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-run 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 1mo 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.

parallel-run

Category: Parallel Development

Usage

/parallel-run <parallel-dir> [options]

Arguments

  • <parallel-dir>: Required - Path to decomposed parallel folder (e.g., parallel/TS-0042-inventory/)
  • --validate: Only validate the directory without executing
  • --status: Show current execution status

Purpose

Execute parallel agent development tasks using the cpo (Claude Parallel Orchestrator) CLI tool. This command:

  1. Validates the parallel directory and manifest.json
  2. Executes parallel agents using git worktrees
  3. Monitors progress and reports results

Prerequisites

  • Run /parallel-decompose first (creates tasks, prompts, manifest.json)
  • cpo tool installed: pip install claude-parallel-orchestrator or pipx install claude-parallel-orchestrator
  • Git working tree is clean (no uncommitted changes)
  • Claude Code CLI available: claude --version

Execution Instructions for Claude Code

When this command is run, Claude Code should delegate to the cpo CLI tool.

0. Parse Arguments

Extract from user input:

  • PARALLEL_DIR: The parallel directory path
  • VALIDATE_ONLY: Boolean, true if --validate specified
  • STATUS_ONLY: Boolean, true if --status specified

1. Check cpo Tool Availability

cpo --help

If cpo is not installed, display:

ERROR: cpo (Claude Parallel Orchestrator) not found

Install with:
  pip install claude-parallel-orchestrator
  # or
  pipx install claude-parallel-orchestrator

Documentation: https://github.com/jpoutrin/claude-parallel-orchestrator

2. Handle --validate Option

If --validate is specified:

cpo validate "$PARALLEL_DIR"

Display the validation output and stop.

3. Handle --status Option

If --status is specified:

cpo status "$PARALLEL_DIR"

Display the status output and stop.

4. Run Parallel Execution

For default execution (no special flags):

cpo run "$PARALLEL_DIR"

The cpo run command will:

  1. Validate the manifest.json
  2. Create git worktrees for each task
  3. Launch Claude agents in parallel (respecting wave dependencies)
  4. Monitor progress and handle failures
  5. Generate execution logs in $PARALLEL_DIR/logs/
  6. Create final report in $PARALLEL_DIR/report.json

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.
