parallel-workflow

A workflow for splitting software tasks across several coding agents so they can work at the same time. It groups tasks by which files they need to change.

In plain words
What is it for?
Use it to dispatch prepared tasks, monitor parallel agents, merge their work, and finish tasks that must run one after another.
Why use it?
It reduces waiting when a project has independent tasks, while helping avoid agents editing the same files and creating conflicts.

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 A, and why

parallel-workflow 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 2d 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 Workflow

Guides users through dispatching ralph-specum spec tasks for parallel execution via Claude Code Agent Teams.

Overview

Ralph Parallel extends ralph-specum by enabling multiple spec tasks to execute simultaneously across Agent Teams teammates. Instead of sequential task-by-task execution, tasks are partitioned into non-conflicting groups and dispatched to separate teammates.

Workflow

1. Create spec normally:     /ralph-specum:start my-feature "goal"
2. Complete spec phases:     research -> requirements -> design -> tasks
3. Dispatch for parallel:    /ralph-parallel:dispatch
   -> Analyzes tasks, partitions by file ownership, creates team, spawns teammates
   -> Lead coordinates execution, runs verify checkpoints, handles serial tasks
4. Monitor progress:         /ralph-parallel:status
5. Integrate results:        /ralph-parallel:merge (worktree only; file-ownership auto-completes)
6. Handle remaining serial:  /ralph-specum:implement (if any tasks remain)

Commands

Command Purpose Key Flags
/ralph-parallel:dispatch Analyze tasks, partition, create team, orchestrate --max-teammates N, --strategy, --dry-run, --abort, --reclaim
/ralph-parallel:status Show parallel execution progress --json, --watch
/ralph-parallel:merge Integrate results / verify consistency --abort, --continue

Strategies

File Ownership (Default)

Each teammate gets exclusive ownership of certain files. No merge needed -- teammates work in the same repo but on different files. The PreToolUse hook (file-ownership-guard.sh) enforces ownership at runtime by blocking writes to non-owned files.

Best for: Most projects. Simple, no merge complexity. Limitation: Tasks sharing files must be serialized.

Worktree

Each teammate gets its own git worktree with a separate branch. Full file access but requires merge step via /ralph-parallel:merge.

Best for: Highly coupled codebases where tasks touch overlapping files. Limitation: Merge conflicts possible, requires explicit merge step.

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.

parallel-workflow is a skill published in the GitHub repository kavanaghpatrick/ralph-parallel (7 stars, last pushed 5mo ago), licensed MIT. It adds 68 tokens to every session and 3,651 once invoked, about $0.0003 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 2026-08-31.
