Hermes Kanban Obsidian Integration

Hermes Kanban Obsidian Integration

Skill by ara.so — Hermes Skills collection.

Overview

Hermes Kanban Bridge is an Obsidian plugin that exposes a REST API (default port 27124) allowing Hermes agents to manage Kanban boards inside your Obsidian vault. Boards are stored as Markdown files with YAML frontmatter, rendered visually by the obsidian-kanban community plugin.

Architecture:

• Hermes Agent → HTTP REST API → hermes-kanban-bridge plugin → Obsidian Vault API → Markdown files → obsidian-kanban visual renderer

Key Features:

• Break goals into structured Kanban boards via API
• Move cards, update metadata, query state in real-time
• Daily standups and weekly review rituals
• Fully local, no cloud dependencies
• Visual board rendering in Obsidian

Installation

Automated Install (Recommended)

# Clone the repository
git clone https://github.com/GumbyEnder/hermes-kanban.git
cd hermes-kanban

# Edit install script to set your vault path
export VAULT_PATH="/path/to/your/ObsidianVault"

# Run automated installer
bash hermes-kanban-install.sh

The script installs:

1. hermes-kanban-bridge plugin (REST API server)
2. obsidian-kanban plugin (visual renderer)
3. Registers both in vault's community-plugins.json

Manual Installation

Build the plugin:

cd plugin
npm install
npm run build

Copy to vault:

VAULT="/path/to/your/vault"
mkdir -p "$VAULT/.obsidian/plugins/hermes-kanban-bridge"
cp main.js manifest.json "$VAULT/.obsidian/plugins/hermes-kanban-bridge/"

Install obsidian-kanban renderer:

KANBAN_DIR="$VAULT/.obsidian/plugins/obsidian-kanban"
mkdir -p "$KANBAN_DIR"
TAG="2.0.51"
for f in main.js manifest.json styles.css; do
  curl -sL "https://github.com/obsidian-community/obsidian-kanban/releases/download/$TAG/$f" -o "$KANBAN_DIR/$f"
done

Enable plugins in Obsidian:

1. Reload Obsidian
2. Settings → Community Plugins → disable Safe Mode
3. Enable "Hermes Kanban Bridge" and "Kanban"
4. Verify notice: "Hermes Kanban Bridge started on port 27124"

Install Hermes skills:

mkdir -p ~/.hermes/profiles/$HERMES_PROFILE/skills/productivity
cp skills/*.md ~/.hermes/profiles/$HERMES_PROFILE/skills/productivity/

Configuration

Plugin Settings (Obsidian → Settings → Hermes Kanban Bridge):

Network Configuration for Remote Access:

If Hermes runs on a different machine, use Tailscale/LAN IP instead of localhost.

Windows firewall rule:

netsh advfirewall firewall add rule name="Hermes Kanban Bridge" dir=in action=allow protocol=TCP localport=27124

Verify listening on all interfaces:

netstat -ano | findstr 27124
# Should show: TCP  0.0.0.0:27124  LISTENING

Python Client Usage

import requests
import os

BASE_URL = os.getenv("HERMES_KANBAN_URL", "http://localhost:27124")

class KanbanClient:
    def __init__(self, base_url=BASE_URL):
        self.base = base_url
    
    def health_check(self):
        """Verify server is running"""
        r = requests.get(f"{self.base}/health")
        return r.json()
    
    def create_board(self, name, columns):
        """Create new Kanban board"""
        r = requests.post(
            f"{self.base}/boards",
            json={"name": name, "columns": columns}
        )
        return r.json()
    
    def add_card(self, board_id, title, column, metadata=None):
        """Add card to board"""
        payload = {"title": title, "column": column}
        if metadata:
            payload["metadata"] = metadata
        r = requests.post(
            f"{self.base}/boards/{board_id}/cards",
            json=payload
        )
        return r.json()
    
    def move_card(self, board_id, card_id, new_column):
        """Move card between columns"""
        r = requests.patch(
            f"{self.base}/boards/{board_id}/cards/{card_id}",
            json={"column": new_column}
        )
        return r.json()
    
    def query_cards(self, board_id, filters=None):
        """Query cards with optional filters"""
        params = filters or {}
        r = requests.get(
            f"{self.base}/boards/{board_id}/cards",
            params=params
        )
        return r.json()
    
    def daily_standup(self, board_id):
        """Run daily standup ritual"""
        r = requests.post(
            f"{self.base}/rituals/standup",
            json={"board_id": board_id}
        )
        return r.json()

# Example usage
client = KanbanClient()

# Verify connection
print(client.health_check())

# Create board
board = client.create_board(
    name="Product Roadmap",
    columns=["Ideas", "Planned", "In Development", "Shipped"]
)
board_id = board["board_id"]

# Add cards
client.add_card(
    board_id,
    "Implement dark mode",
    "Planned",
    metadata={"priority": "medium", "estimate": "3d"}
)

# Query blocked items
blocked = client.query_cards(board_id, {"status": "blocked"})
print(f"Blocked cards: {len(blocked['cards'])}")

# Run standup
standup = client.daily_standup(board_id)
print(standup["summary"])

Board Markdown Format

Boards are stored as Markdown with YAML frontmatter:

---
kanban-plugin: board
---

## Backlog

- [ ] Design landing page #high @alice
- [ ] Set up CI/CD pipeline #medium @bob

## In Progress

- [ ] Implement authentication #high @alice
  - Started: 2026-05-15
  - Blocked: waiting on API keys

## Review

- [ ] Write user documentation #low @carol

## Done

- [x] Initialize project repository
  - Completed: 2026-05-14

Important: The kanban-plugin: board frontmatter triggers visual rendering. Without it, boards display as plain Markdown.

Common Patterns

Breaking Down a Project

def break_down_project(client, project_name, tasks):
    """Create board and populate with tasks"""
    board = client.create_board(
        name=project_name,
        columns=["Backlog", "In Progress", "Review", "Done"]
    )
    board_id = board["board_id"]
    
    for task in tasks:
        client.add_card(
            board_id,
            task["title"],
            "Backlog",
            metadata=task.get("metadata", {})
        )
    
    return board_id

# Usage
tasks = [
    {"title": "Research competitors", "metadata": {"priority": "high"}},
    {"title": "Draft wireframes", "metadata": {"priority": "medium"}},
    {"title": "Set up analytics", "metadata": {"priority": "low"}}
]

board_id = break_down_project(client, "Market Analysis", tasks)

Automated Workflow Progression

def progress_workflow(client, board_id):
    """Move cards through workflow automatically"""
    # Get all cards in Review
    cards = client.query_cards(board_id, {"column": "Review"})
    
    for card in cards["cards"]:
        # Check if ready to move (example: all subtasks done)
        if card_is_complete(card):
            client.move_card(board_id, card["id"], "Done")
            print(f"Completed: {card['title']}")

def card_is_complete(card):
    """Example validation logic"""
    metadata = card.get("metadata", {})
    return metadata.get("reviewed", False) and metadata.get("tests_passing", False)

Daily Ritual Integration

import schedule
import time

def daily_standup_job():
    """Run standup for all active boards"""
    client = KanbanClient()
    
    # Get all boards
    boards = requests.get(f"{client.base}/boards").json()
    
    for board in boards["boards"]:
        if board.get("active", True):
            result = client.daily_standup(board["id"])
            send_notification(result["summary"])

# Schedule daily at 9 AM
schedule.every().day.at("09:00").do(daily_standup_job)

while True:
    schedule.run_pending()
    time.sleep(60)

Testing

The project includes 105 tests (59 unit, 46 E2E):

# All tests
pytest tests/

# E2E only
pytest tests/e2e/

# Skip slow TUI tests
pytest tests/e2e/ -k "not tui"

# Mock API server (no Obsidian required)
python tests/e2e/mock_api_server.py

Mock API for development:

# tests/e2e/mock_api_server.py implements all REST endpoints
# Use for testing without running Obsidian

import requests
# Start mock server on port 27125
response = requests.get("http://localhost:27125/health")
assert response.json()["ok"] == True

Troubleshooting

Connection Refused

Symptoms: curl: Failed to connect to localhost port 27124

Solutions:

1. Verify plugin is enabled: Settings → Community Plugins → Hermes Kanban Bridge = ON
2. Look for notice "Hermes Kanban Bridge started on port 27124"
3. Toggle plugin off/on to restart server
4. Check port not in use: lsof -i :27124 (Unix) or netstat -ano | findstr 27124 (Windows)

Board Shows as Markdown List

Symptoms: Board opens as plain text instead of visual kanban

Solution: Add YAML frontmatter to top of file:

---
kanban-plugin: board
---

All API-created boards include this automatically. Manually created boards need it added.

Remote Access Not Working

Symptoms: Can't connect from Hermes on different machine

Solutions:

1. Use Obsidian machine's Tailscale/LAN IP instead of localhost
2. Verify server binds to 0.0.0.0 not 127.0.0.1:

   netstat -ano | findstr 27124
   # Should show: TCP  0.0.0.0:27124  LISTENING
   

3. Add firewall rule (Windows):

   netsh advfirewall firewall add rule name="Hermes Kanban Bridge" dir=in action=allow protocol=TCP localport=27124
   

4. macOS: System Settings → Network → Firewall → allow Obsidian

Plugin Not Appearing

Symptoms: Plugin not in Community Plugins list

Solution: Quit Obsidian completely (not just reload), then reopen. Obsidian requires full restart to detect new plugin folders.

Port Conflict

Symptoms: Server fails to start, port already in use

Solution:

1. Change port: Settings → Hermes Kanban Bridge → Port → set to 27125 (or other)
2. Toggle plugin off/on to apply
3. Update Hermes skill configs and HERMES_KANBAN_URL to new port

Environment Variables

# REST API base URL (default: http://localhost:27124)
export HERMES_KANBAN_URL="http://192.168.1.100:27124"

# Hermes profile for skills installation
export HERMES_PROFILE="frodo"

# Obsidian vault path for scripts
export VAULT_PATH="/Users/alice/Documents/ObsidianVault"

Integration with Hermes Agent

Once skills are installed (~/.hermes/profiles/*/skills/productivity/), interact naturally:

Voice Commands:

• "Break down the Q3 launch into a Kanban board"
• "Run my daily standup"
• "What cards are blocked?"
• "Move the authentication task to In Progress"
• "Give me a weekly review"

Hermes uses the installed skills to translate commands into REST API calls automatically.
