+## 🤖 Agent Skills Management
+
+This configuration includes automatic management of AI agent skills for OpenCode and Claude Code integration.
+
+### Features
+- **Automatic Installation**: Skills install automatically with opencode or claude bundles
+- **Upstream Updates**: Clean update mechanism from superpowers repository
+- **Local Customization**: Override or extend skills in repository
+- **Cross-Platform**: Works on all configured systems (macOS and NixOS)
+- **Validation**: Skills follow Agent Skills specification compliance
+
+### Usage
+
+```bash
+# Check skills status
+task agent-skills:status
+
+# Update skills from upstream
+task agent-skills:update
+
+# Validate skills format
+task agent-skills:validate
+
+# List available skills
+skills-list
+```
+
+### Configuration
+
+Agent skills are automatically enabled when either `opencode` or `claude` bundles are active. Skills are installed to:
+- `~/.config/opencode/skills/` - Primary skills directory
+- `~/.config/opencode/superpowers/skills/` - Superpowers compatibility
+
+See [docs/agent-skills.md](docs/agent-skills.md) for detailed documentation.
+
 ### SSH Commit Signing
 
 This configuration supports SSH-based git commit signing using 1Password, providing a modern alternative to GPG signing.

+# Agent Skills Management
+
+## Overview
+
+This system provides comprehensive management of AI agent skills through Nix, ensuring consistent installation across all your development environments.
+
+## Architecture
+
+### Module Structure
+```
+modules/home-manager/agent-skills/
+├── default.nix          # Main module definition
+├── skills.nix           # Skills installation logic
+├── updates.nix          # Update mechanism
+└── skills/              # Skill definitions
+    ├── using-superpowers/
+    ├── brainstorming/
+    └── ...
+```
+
+### Integration Points
+
+1. **Bundles Integration**: Auto-enabled by opencode/claude bundles
+2. **Home-Manager Integration**: Manages file placement in user home directory
+3. **Update System**: Git-based updates from upstream superpowers
+4. **Task Integration**: Taskfile commands for common operations
+
+## Usage Guide
+
+### Checking Status
+```bash
+task agent-skills:status
+```
+Shows current skills count, version tracking, and directory status.
+
+### Updating Skills
+```bash
+task agent-skills:update
+```
+Fetches latest skills from upstream superpowers repository while preserving custom skills.
+
+### Validating Skills
+```bash
+task agent-skills:validate
+```
+Checks that all skills follow the Agent Skills specification.
+
+### Listing Skills
+```bash
+skills-list
+```
+Lists all installed skills by name.
+
+## Customization
+
+### Adding Custom Skills
+1. Create skill directory: `modules/home-manager/agent-skills/skills/my-skill/`
+2. Add `SKILL.md` with proper frontmatter
+3. Rebuild system: `task build`
+4. Skills will be automatically installed to user directories
+
+### Modifying Existing Skills
+Edit skills in `modules/home-manager/agent-skills/skills/` - changes will be applied on next rebuild.
+
+## Troubleshooting
+
+### Skills Not Found
+1. Check bundle is enabled: `task agent-skills:status`
+2. Verify directories exist: `ls -la ~/.config/opencode/skills/`
+3. Rebuild system: `task build`
+
+### Update Failures
+1. Check internet connectivity
+2. Verify git access to GitHub
+3. Check permissions on skills directories
+
+### Specification Violations
+1. Run validation: `task agent-skills:validate`
+2. Check frontmatter format in `SKILL.md` files
+3. Ensure directory names match skill names
+
+## Development
+
+### Adding New Update Sources
+Modify `modules/home-manager/agent-skills/updates.nix` to add additional upstream repositories.
+
+### Extending Validation
+Enhance validation logic in `Taskfile.yml` to check for additional requirements.
+
+## Security Considerations
+
+- Skills execute as part of AI assistant - review custom skills carefully
+- Updates fetch from external repository - verify commit hashes
+- Skills have access to system through AI assistant permissions
