Installation

Prerequisites

git clone https://github.com/msitarzewski/agency-agents.git
cd agency-agents

Claude Code (Recommended)

# Copy all agents to Claude's agents directory
cp -r agency-agents/* ~/.claude/agents/

Using Agents in Claude Code

Activating a Single Agent

# In Claude Code chat:
Activate the Backend Architect agent and help me design a REST API for a multi-tenant SaaS app.

Using Multiple Agents in Sequence

# First, design the system
Activate the Software Architect agent. Design the domain model for an e-commerce platform.

# Then implement
Now activate the Senior Developer agent and implement the Order aggregate in Laravel.

# Then review
Activate the Code Reviewer agent and review the implementation above.

Referencing an Agent File Directly

# Pass an agent as a system prompt in Claude CLI
claude --system-prompt "$(cat ~/.claude/agents/engineering-frontend-developer.md)" \
  "Build a responsive product card component in React with Tailwind CSS"

---

Using Agents in Cursor

After running ./scripts/install.sh --tool cursor, agent rules land in .cursor/rules/. Reference them in chat:

@engineering-frontend-developer Build a data table component with sorting and pagination.

Or set a default rule in .cursor/rules/default.mdc:

---
alwaysApply: true
---

You are operating as the Senior Developer agent from The Agency.
Refer to .cursor/rules/engineering-senior-developer.md for your full persona and workflows.

---

Using Agents with Aider

# Use a single agent as the system prompt
aider --system-prompt "$(cat agency-agents/engineering/engineering-security-engineer.md)"

# Or reference in .aider.conf.yml
echo "system-prompt: agency-agents/engineering/engineering-devops-automator.md" >> .aider.conf.yml

---

Using Agents in Windsurf

./scripts/install.sh --tool windsurf
# Agents are written to .windsurf/rules/

Activate in chat:

Use the UX Architect agent rules from .windsurf/rules/ to audit my CSS architecture.

---

Real Workflow Examples

Full-Stack Feature with Multiple Agents

# 1. Architecture phase
cat > task.md << 'EOF'
I need to add real-time notifications to my Node.js + React app.
Users should see in-app alerts and optionally receive email digests.
EOF

# Invoke Software Architect
claude --system-prompt "$(cat ~/.claude/agents/engineering-software-architect.md)" < task.md

# 2. Backend implementation
claude --system-prompt "$(cat ~/.claude/agents/engineering-backend-architect.md)" \
  "Implement the notification service based on the architecture above using PostgreSQL LISTEN/NOTIFY and Socket.io"

# 3. Frontend implementation
claude --system-prompt "$(cat ~/.claude/agents/engineering-frontend-developer.md)" \
  "Build the React notification bell component that connects to the Socket.io feed"

# 4. Security review
claude --system-prompt "$(cat ~/.claude/agents/engineering-security-engineer.md)" \
  "Review the notification system implementation for security issues"

Code Review Workflow

# Generate a diff and pipe to the Code Reviewer agent
git diff main..feature/payment-integration | \
  claude --system-prompt "$(cat ~/.claude/agents/engineering-code-reviewer.md)" \
  "Review this PR diff. Focus on security, correctness, and maintainability."

Database Optimization

# Paste slow query log and activate Database Optimizer
claude --system-prompt "$(cat ~/.claude/agents/engineering-database-optimizer.md)" << 'EOF'
Here is a slow query from our PostgreSQL logs (avg 4200ms):

SELECT u.*, p.*, o.*
FROM users u
LEFT JOIN profiles p ON p.user_id = u.id
LEFT JOIN orders o ON o.user_id = u.id
WHERE u.created_at > NOW() - INTERVAL '30 days'
ORDER BY o.created_at DESC;

Table sizes: users=2M rows, orders=18M rows. No indexes on created_at columns.
EOF

Incident Response

# Structured incident kick-off
claude --system-prompt "$(cat ~/.claude/agents/engineering-incident-response-commander.md)" << 'EOF'
SEV-1 INCIDENT: Payment processing returning 503 errors since 14:32 UTC.
Error rate: 94%. Affected: checkout, subscription renewals.
Recent deploys: payment-service v2.4.1 at 14:15 UTC.
EOF

Creating Custom Agents

Agent files follow a consistent markdown structure:

# 🎯 Agent Name

## Identity
You are [Name], [role] at The Agency...

## Core Mission
[What this agent optimizes for]

## Personality & Communication Style
- [Trait 1]
- [Trait 2]

## Workflows

### [Workflow Name]
1. [Step 1]
2. [Step 2]

## Deliverables
- [Concrete output 1]
- [Concrete output 2]

## Success Metrics
- [Measurable outcome]

Save custom agents to agency-agents/custom/ and re-run ./scripts/convert.sh to generate tool integrations.

Contributing New Agents

# Fork and clone
git clone https://github.com/YOUR_USERNAME/agency-agents.git

# Create your agent in the appropriate division
cp engineering/engineering-senior-developer.md \
   engineering/engineering-YOUR-SPECIALTY.md

# Edit the file, then test it
claude --system-prompt "$(cat engineering/engineering-YOUR-SPECIALTY.md)" \
  "Give me a sample deliverable to demonstrate your capabilities"

# Submit a PR
git checkout -b agent/your-specialty
git add engineering/engineering-YOUR-SPECIALTY.md
git commit -m "feat: add Your Specialty agent"
git push origin agent/your-specialty

---

Troubleshooting

Agents not found in Claude Code

ls ~/.claude/agents/
# If empty, re-run:
cp -r /path/to/agency-agents/* ~/.claude/agents/

convert.sh fails with permission error

chmod +x scripts/convert.sh scripts/install.sh
./scripts/convert.sh

Cursor not picking up agent rules

# Rules must be in project root .cursor/rules/
ls .cursor/rules/
# Re-run installer targeting cursor
./scripts/install.sh --tool cursor

Agent personality not activating

• Be explicit: "Activate the Frontend Developer agent" rather than just referencing the topic
• Paste the agent file contents directly into the system prompt if tool integration isn't working
• For Claude Code, confirm agents directory: claude config get agentsDir

Agent conflicts when using multiple

• Activate one agent per conversation session
• For multi-agent workflows, use separate sessions or Claude Code's subagent feature
• Sequence agents explicitly: architect → implement → review
