Building an AI Development Team with Hermes

With the advancement of AI technology, more development work can be assisted by AI. However, a single AI assistant often struggles to handle all roles in complex projects — product managers need to understand requirements, architects need to design systems, developers need to write code, and QA needs to verify quality.

Hermes’s Profile mechanism allows us to define different identities and responsibilities for AI, building a complete AI development team. This article details how to set up and use this system.

Core Concept: Profile and Role Isolation

Hermes’s Profile is an independent configuration unit, each Profile has:

• SOUL.md — Role identity definition, determines AI’s thinking style and work boundaries
• skills/ — Dedicated skills directory, containing workflow knowledge for that role
• memories/ — Independent memory, different roles don’t interfere with each other
• workspace/ — Working directory, storing output documents

This differs from regular multi-turn conversations: the PM role won’t suddenly start writing code, architects won’t overstep to modify requirements, each role strictly works within their defined responsibilities.

    - ui does not write frontend code or make technical decisions
    - sa does not write specific code or make requirement decisions
    - dev does not make requirement or architecture decisions
    - qa does not write feature code or make requirement decisions

Role Boundary Reference Table

The benefit of clear boundaries is avoiding “role crossing” — PM won’t suddenly start writing code, Dev won’t arbitrarily modify requirements. Everything has a clear responsible person.

Key Points:

1. UI phase cannot be skipped — Even for small features, UI design needs to confirm interaction methods
2. UI and SA are parallel — After requirements are confirmed, interface design and architecture design can proceed simultaneously
3. Output documentation — Each phase’s output must be documented and passed to downstream

Practice: Manual Switch Mode

The simplest usage is manually switching Profiles:

# Phase 1: PM analyzes requirements
hermes -p pm
> Analyze requirements for "User Login" feature, output user stories and acceptance criteria
# Output: workspace/requirement-analysis-user-login.md

# Phase 2: UI designs interface (new terminal)
hermes -p ui
> Design interface based on requirement analysis document workspace/requirement-analysis-user-login.md
# Output: workspace/ui-design-user-login.md

# Phase 2: SA designs architecture (can be parallel)
hermes -p sa
> Design login module architecture and API based on requirement analysis
# Output: workspace/architecture-design-user-login.md

# Phase 3: Dev implements
hermes -p dev
> Implement user login feature based on UI design and architecture design
# Output: Feature code + unit tests

# Phase 4: QA tests and verifies
hermes -p qa
> Test user login feature, verify if it meets acceptance criteria
# Output: Test report

Each role only sees information within their responsibility scope, following upstream output to work.

Role Task Coordination

After having team configuration, the key question is how to coordinate tasks between different roles. This requires an orchestrator role to schedule.

Orchestrator Responsibilities

The orchestrator is responsible for:

1. Task decomposition — Break down user requests into subtasks for each role
2. Schedule execution — Schedule each Profile to execute tasks according to dependencies
3. Context passing — Pass upstream outputs to downstream roles
4. Progress monitoring — Monitor execution progress, handle exceptions
5. Result integration — Integrate outputs from each role, report to user

Three Coordination Methods Comparison

Recommended Strategy:

• Quick development tasks (complete within this session): Use tmux
• Long-term projects (need cross-session persistence): Use Kanban

tmux Method: Real-time Coordination

For quick development tasks, tmux is the most flexible method:

# Phase 1: Start PM to analyze requirements
tmux new-session -d -s pm-agent -x 120 -y 40 'hermes -p pm'
tmux send-keys -t pm-agent 'Analyze requirements for "User Login" feature, output user stories and acceptance criteria' Enter

# Wait and get PM output
sleep 30 && tmux capture-pane -t pm-agent -p -S -100 > /tmp/pm-output.txt

# Phase 2: Start UI and SA in parallel (pass PM's output)
tmux new-session -d -s ui-agent 'hermes -p ui'
tmux new-session -d -s sa-agent 'hermes -p sa'

tmux send-keys -t ui-agent 'Design login interface based on requirement analysis...' Enter
tmux send-keys -t sa-agent 'Design login API architecture based on requirement analysis...' Enter

# Phase 3: Start Dev implementation (wait for UI + SA to complete)
tmux new-session -d -s dev-agent 'hermes -p dev'
tmux send-keys -t dev-agent 'Implement login feature based on UI design and architecture design' Enter

# Phase 4: Start QA testing
tmux new-session -d -s qa-agent 'hermes -p qa'
tmux send-keys -t qa-agent 'Test login feature, verify acceptance criteria' Enter

Key Technique: Follow-up Prompt

When Agent executes subtask and may get stuck, need to send subsequent instruction:

1
2
3
4
5

# Check Agent status
tmux capture-pane -t dev-agent -p -S -50

# Send follow-up to make it continue
tmux send-keys -t dev-agent 'Please continue generating frontend code...' Enter

Context Passing Methods

Information passing between roles through two methods:

Method 1: Document Passing (Recommended)

Each role outputs documents to workspace/ directory, downstream roles read:

1
2
3
4
5

workspace/
├── requirement-analysis-user-login.md      # PM output
├── ui-design-user-login.md                 # UI output
├── architecture-design-user-login.md       # SA output
└── test-report-user-login.md               # QA output

Method 2: Direct Passing (tmux)

Orchestrator captures upstream output, directly injects into downstream prompt:

1
2

pm_output=$(tmux capture-pane -t pm-agent -p -S -100)
tmux send-keys -t ui-agent "Design interface based on following requirements:\n$pm_output" Enter

Coordination Report Template

After task completion, orchestrator should output standardized report:

Key Role of SOUL.md

From the examples above, the core roles of SOUL.md are:

1. Identity Definition — Clearly define role positioning and professional domain
2. Responsibility Boundaries — Clearly define “responsible for” and “not responsible for”
3. Output Standards — Define standardized output formats
4. Collaboration Constraints — Prevent roles from crossing boundaries to work

This is more powerful than simple role descriptions: it’s like a “role contract”, forcing AI to work within specific boundaries, won’t role-cross.

FAQ

Q: Why not use one all-powerful AI to complete all work?

One role doing everything leads to:

• Writing code without clear requirements
• Architecture decisions not documented
• Incomplete test coverage
• Confused responsibilities, difficult to trace

Role separation enforces process discipline, each phase has clear output.

Q: How do roles pass information?

Through documents in workspace/ directory:

• PM output → workspace/requirement-analysis-*.md
• UI output → workspace/ui-design-*.md
• SA output → workspace/architecture-design-*.md

Downstream roles read upstream documents to proceed.

Q: What if issues are found?

Each role discovering issues should:

1. Mark the issue in their output document
2. If it’s an upstream issue, feedback to upstream role
3. Don’t cross boundaries to solve issues

Example: Dev finds architecture design has issues, should mark in output and notify SA to redesign, not modify architecture themselves.

Q: What to do if Agent gets stuck in tmux mode?

Agent calling clarify in tmux session will wait for user input, causing timeout (default 120 seconds). Solutions:

1. Avoid using clarify — PM role should avoid asking questions, use default assumptions to proceed
2. Send follow-up — Orchestrator checks output then sends subsequent instruction:

   1	tmux send-keys -t dev-agent 'Please continue generating frontend code...' Enter

Q: How to avoid role crossing?

Strictly follow boundaries defined in SOUL.md:

• PM doesn’t make technical decisions (like technical selection, architecture)
• Dev doesn’t modify requirements (even if discovering issues, should feedback to PM)
• QA doesn’t write feature code (only test code)

Orchestrator should immediately remind when discovering role crossing, if necessary re-execute that phase.

Q: What to do if Kanban task creation fails?

Common reasons:

• Profile configuration incomplete — Missing model or api_key configuration
• Environment variables not linked — Missing .env symlink in Profile directory
• Parameter error — Using --tenant instead of --board to group tasks

# Check Profile configuration
cat ~/.hermes/profiles/dev/config.yaml

# Ensure .env link exists
ls -la ~/.hermes/profiles/dev/.env

Summary

Hermes’s Profile mechanism allows us to build an AI development team with clear responsibilities:

• Role isolation: Each role has independent identity and memory
• Clear boundaries: Strictly limit each role’s responsibility scope
• Standardized workflow: Standardized development process and output passing
• Extensible: Can add new roles as needed

This approach is more suitable for complex projects than a single AI assistant, each role focuses on their domain, producing more professional and standardized output.
