flow-parallel

flow-parallel is a skill for Claude Code, Codex from nyldn/claude-octopus. It costs 23 tokens per session (6,995 once invoked), scanned A, original, MIT.

A process for splitting large code changes, migrations, or several issue fixes into parallel work packages with quality checks. It uses separate coding-agent processes and requires decisions about scope, dependencies, and package count first.

In plain words
What is it for?
Use it to plan parallel implementation of a compound task, assign separate work packages, and run checks before combining the results.
Why use it?
It helps coordinate independent work while reducing overlapping edits, missed dependencies, and unreviewed results.

About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

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

flow-parallel 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 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.

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.

STOP - SKILL ALREADY LOADED

DO NOT call Skill() again. DO NOT load any more skills. Execute directly.


EXECUTION CONTRACT (MANDATORY - CANNOT SKIP)

This skill uses ENFORCED execution mode. You MUST follow this exact 7-step sequence.

Architectural Principle: Task tool subagents do NOT load plugins. Independent claude -p processes DO. This skill spawns independent claude -p processes so each work package gets the full Octopus plugin, its own Double Diamond, agents, and quality gates.


STEP 1: Clarifying Questions (MANDATORY)

Ask via AskUserQuestion BEFORE any other action.

You MUST gather these inputs from the user — without scope, count, and dependency answers, the decomposition will be generic and produce overlapping work packages that cause merge conflicts:

AskUserQuestion with these questions:

1. **Compound task**: What compound task should be decomposed?
   - Use inline args if provided (e.g., /octo:parallel "build auth system")
   - If no args: ask "What compound task should I decompose into parallel work packages?"

2. **Work package count**: How many work packages?
   - Options: "3 (Recommended)", "4", "5", "Custom (up to 10)"
   - Default: 3-5 is optimal

3. **Dependencies**: Are the work packages independent?
   - "Fully independent - no dependencies between packages (Recommended)"
   - "Some dependencies - packages may need to share interfaces"
   - "Sequential dependencies - packages must complete in order"

If user provided a description inline with the command (e.g., /octo:parallel build a full auth system with OAuth, RBAC, and audit logging), use that as the task description but STILL ask remaining questions (count, dependencies).

If user says "skip" for any question, use defaults: 3 work packages, fully independent.

DO NOT PROCEED TO STEP 2 until questions answered.


STEP 2: Display Visual Indicators (MANDATORY - BLOCKING)

MANDATORY: You MUST use the Bash tool to run this provider check BEFORE displaying the banner. Do NOT skip it. Do NOT assume availability.

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.

flow-parallel is a skill published in the GitHub repository nyldn/claude-octopus (4,045 stars, last pushed today), licensed MIT. It adds 23 tokens to every session and 6,995 once invoked, about $0.0001 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 2026-08-30.
