Opencode Agent Skills & Configurations

Central repository for Opencode Agent Skills, AI agent configurations, custom commands, and AI-assisted workflows. This is an extensible framework for building productivity systems, automations, knowledge management, and specialized AI capabilities.

🎯 What This Repository Provides

This repository serves as a personal AI operating system - a collection of skills, agents, and configurations that extend Opencode's capabilities for:

• Productivity & Task Management - PARA methodology, GTD workflows, project tracking
• Knowledge Management - Note-taking, research workflows, information organization
• Communications - Email management, meeting scheduling, follow-up tracking
• AI Development - Tools for creating new skills and agent configurations
• Memory & Context - Persistent memory systems, conversation analysis
• Custom Workflows - Domain-specific automation and specialized agents

🚀 Getting Started

Prerequisites

• Opencode - AI coding assistant (opencode.dev)
• Nix (optional) - For declarative deployment via home-manager
• Python 3 - For skill validation and creation scripts
• bd (beads) (optional) - For issue tracking

Installation

Option 1: Nix Flake (Recommended)

This repository is consumed as a non-flake input by your NixOS configuration:

# In your flake.nix
inputs.agents = {
  url = "git+https://code.m3ta.dev/m3tam3re/AGENTS";
  flake = false;  # Pure files, not a Nix flake
};

# In your home-manager module (e.g., opencode.nix)
xdg.configFile = {
  "opencode/skill".source = "${inputs.agents}/skill";
  "opencode/context".source = "${inputs.agents}/context";
  "opencode/command".source = "${inputs.agents}/command";
  "opencode/prompts".source = "${inputs.agents}/prompts";
};

# Agent config is embedded into config.json, not deployed as files
programs.opencode.settings.agent = builtins.fromJSON 
  (builtins.readFile "${inputs.agents}/agent/agents.json");

Rebuild your system:

home-manager switch

Note: The agent/ directory is NOT deployed as files. Instead, agents.json is read at Nix evaluation time and embedded into the opencode config.json.

Option 2: Manual Installation

Clone and symlink:

# Clone repository
git clone https://github.com/yourusername/AGENTS.git ~/AGENTS

# Create symlink to Opencode config directory
ln -s ~/AGENTS ~/.config/opencode

Verify Installation

Check that Opencode can see your skills:

# Skills should be available at ~/.config/opencode/skill/
ls ~/.config/opencode/skill/

🎨 Creating Your First Skill

Skills are modular packages that extend Opencode with specialized knowledge and workflows.

1. Initialize a New Skill

python3 skill/skill-creator/scripts/init_skill.py my-skill-name --path skill/

This creates:

• skill/my-skill-name/SKILL.md - Main skill documentation
• skill/my-skill-name/scripts/ - Executable code (optional)
• skill/my-skill-name/references/ - Reference documentation (optional)
• skill/my-skill-name/assets/ - Templates and files (optional)

2. Edit the Skill

Open skill/my-skill-name/SKILL.md and customize:

---
name: my-skill-name
description: What it does and when to use it. Include trigger keywords.
compatibility: opencode
---

# My Skill Name

## Overview

[Your skill instructions for Opencode]

3. Validate the Skill

python3 skill/skill-creator/scripts/quick_validate.py skill/my-skill-name

4. Test the Skill

Test your skill without deploying via home-manager:

# Use the test script to validate and list skills
./scripts/test-skill.sh my-skill-name    # Validate specific skill
./scripts/test-skill.sh --list           # List all dev skills
./scripts/test-skill.sh --run            # Launch opencode with dev skills

The test script creates a temporary config directory with symlinks to this repo's skills, allowing you to test changes before committing.

Chiron is a personal AI assistant focused on productivity and task management. Named after the wise centaur from Greek mythology, Chiron provides:

• Task and project management guidance
• Daily and weekly review workflows
• Skill routing based on user intent
• Integration with productivity tools (Obsidian, ntfy, n8n)

Modes:

• Chiron (Plan Mode) - Read-only analysis and planning (prompts/chiron.txt)

Triggers: Personal productivity requests, task management, reviews, planning

🛠️ Development Workflow

Issue Tracking with Beads

This project uses beads for AI-native issue tracking:

bd ready              # Find available work
bd create "title"     # Create new issue
bd update <id> --status in_progress
bd close <id>         # Complete work
bd sync               # Sync with git

Quality Gates

Before committing:

1. Validate skills: ./scripts/test-skill.sh --validate or python3 skill/skill-creator/scripts/quick_validate.py skill/<name>
2. Test locally: ./scripts/test-skill.sh --run to launch opencode with dev skills
3. Check formatting: Ensure YAML frontmatter is valid
4. Update docs: Keep README and AGENTS.md in sync

Session Completion

When ending a work session:

1. File beads issues for remaining work
2. Run quality gates
3. Update issue status
4. Push to remote (mandatory):

   git pull --rebase
   bd sync
   git push
   

5. Verify changes are pushed

See AGENTS.md for complete developer documentation.
