What Swarm Pr by spencermarx is

Swarm Pr by spencermarx is a subagent published in the spencermarx/open-code-review repository on GitHub, which has about 369 stars. The repository describes itself as: “AI-powered multi-agent code review. Simulates a customizable team of Engineers performing code review with built-in discourse.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Swarm Pr and get back a compact result.

How to install Swarm Pr by spencermarx

Claude Code

  1. Download swarm-pr.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Overview

Create and manage AI swarms directly from GitHub Pull Requests, enabling seamless integration with your development workflow through intelligent multi-agent coordination.

Core Features

1. PR-Based Swarm Creation

# Create swarm from PR description using gh CLI
gh pr view 123 --json body,title,labels,files | npx claude-flow@v3alpha swarm create-from-pr

# Auto-spawn agents based on PR labels
gh pr view 123 --json labels | npx claude-flow@v3alpha swarm auto-spawn

# Create swarm with PR context
gh pr view 123 --json body,labels,author,assignees | \
  npx claude-flow@v3alpha swarm init --from-pr-data

2. PR Comment Commands

Execute swarm commands via PR comments:

<!-- In PR comment -->
/swarm init mesh 6
/swarm spawn coder "Implement authentication"
/swarm spawn tester "Write unit tests"
/swarm status

3. Automated PR Workflows

# .github/workflows/swarm-pr.yml
name: Swarm PR Handler
on:
  pull_request:
    types: [opened, labeled]
  issue_comment:
    types: [created]

jobs:
  swarm-handler:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Handle Swarm Command
        run: |
          if [[ "${{ github.event.comment.body }}" == /swarm* ]]; then
            npx claude-flow@v3alpha github handle-comment \
              --pr ${{ github.event.pull_request.number }} \
…

PR Label Integration

Automatic Agent Assignment

Map PR labels to agent types:

{
  "label-mapping": {
    "bug": ["debugger", "tester"],
    "feature": ["architect", "coder", "tester"],
    "refactor": ["analyst", "coder"],
    "docs": ["researcher", "writer"],
    "performance": ["analyst", "optimizer"]
  }
}

Label-Based Topology

# Small PR (< 100 lines): ring topology
# Medium PR (100-500 lines): mesh topology  
# Large PR (> 500 lines): hierarchical topology
npx claude-flow@v3alpha github pr-topology --pr 123

PR Swarm Commands

Initialize from PR

# Create swarm with PR context using gh CLI
PR_DIFF=$(gh pr diff 123)
PR_INFO=$(gh pr view 123 --json title,body,labels,files,reviews)

npx claude-flow@v3alpha github pr-init 123 \
  --auto-agents \
  --pr-data "$PR_INFO" \
  --diff "$PR_DIFF" \
  --analyze-impact

Progress Updates

# Post swarm progress to PR using gh CLI
PROGRESS=$(npx claude-flow@v3alpha github pr-progress 123 --format markdown)

gh pr comment 123 --body "$PROGRESS"

# Update PR labels based on progress
if [[ $(echo "$PROGRESS" | grep -o '[0-9]\+%' | sed 's/%//') -gt 90 ]]; then
  gh pr edit 123 --add-label "ready-for-review"
fi

Code Review Integration

# Create review agents with gh CLI integration
PR_FILES=$(gh pr view 123 --json files --jq '.files[].path')

# Run swarm review
REVIEW_RESULTS=$(npx claude-flow@v3alpha github pr-review 123 \
  --agents "security,performance,style" \
  --files "$PR_FILES")

# Post review comments using gh CLI
echo "$REVIEW_RESULTS" | jq -r '.comments[]' | while read -r comment; do
  FILE=$(echo "$comment" | jq -r '.file')
  LINE=$(echo "$comment" | jq -r '.line')
  BODY=$(echo "$comment" | jq -r '.body')
  
  gh pr review 123 --comment --body "$BODY"
done

Advanced Features

1. Multi-PR Swarm Coordination

# Coordinate swarms across related PRs
npx claude-flow@v3alpha github multi-pr \
  --prs "123,124,125" \
  --strategy "parallel" \
  --share-memory

2. PR Dependency Analysis

# Analyze PR dependencies
npx claude-flow@v3alpha github pr-deps 123 \
  --spawn-agents \
  --resolve-conflicts

3. Automated PR Fixes

# Auto-fix PR issues

  --commit-fixes

Best Practices

1. PR Templates

<!-- .github/pull_request_template.md -->
## Swarm Configuration
- Topology: [mesh/hierarchical/ring/star]
- Max Agents: [number]
- Auto-spawn: [yes/no]
- Priority: [high/medium/low]

## Tasks for Swarm
- [ ] Task 1 description
- [ ] Task 2 description

2. Status Checks

# Require swarm completion before merge
required_status_checks:
  contexts:
    - "swarm/tasks-complete"
    - "swarm/tests-pass"
    - "swarm/review-approved"

3. PR Merge Automation

# Auto-merge when swarm completes using gh CLI
# Check swarm completion status
SWARM_STATUS=$(npx claude-flow@v3alpha github pr-status 123)

if [[ "$SWARM_STATUS" == "complete" ]]; then
  # Check review requirements
  REVIEWS=$(gh pr view 123 --json reviews --jq '.reviews | length')
  
  if [[ $REVIEWS -ge 2 ]]; then
    # Enable auto-merge
    gh pr merge 123 --auto --squash

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
