dox-yaml - SKILL.md Agent Skill

name: dox-yaml description: "Create and configure dox.yaml files for the Docker Compose wrapper CLI. Use when the user asks to: (1) Create or set up a dox.yaml configuration file, (2) Add profiles, aliases, or hooks to their Docker Compose setup, (3) Configure environment-specific compose files like dev/prod/staging, (4) Set up automation hooks for container lifecycle events, (5) Define command shortcuts for common Docker Compose operations. The dox.yaml file is the project-local configuration for the 'dox' CLI tool that simplifies multi-file Docker Compose setups."

dox.yaml Configuration Creator

Create and configure dox.yaml files for the Docker Compose wrapper CLI.

Quick Start

Ask the user what they need:

Project structure - How many compose files? What naming pattern?
Environments - dev, prod, staging, etc.?
Automation needs - Pre/post hooks? Command aliases?

Then create dox.yaml in the project root.

Schema Reference

File Structure

version: 1                    # Required

defaults:                     # Optional
  profile: "dev"             # Default profile to use
  slice: "dev"               # Default slice (fallback)
  auto_detect: true          # Detect profile from git branch

profiles:                     # Environment configurations
  dev:
    slices: [dev]            # compose.dev.yaml
  prod:
    slices: [prod]
    extends: dev             # Inherit dev's slices

env_files:                    # Reusable env file mappings
  dev: ".env.dev"
  prod: ".env.prod"

aliases:                      # Command shortcuts
  fresh: "down -v && up --build -d"

hooks:                        # Lifecycle hooks
  pre_up:
    - echo "Starting..."
  post_up:
    - echo "Ready!"

Discovery Configuration

discovery:
  enabled: true              # Auto-discover compose files
  pattern: "compose.*.yaml"  # File pattern
  base: "compose.yaml"       # Base file name

Auto-discovery finds:

Base: compose.yaml (preferred), docker-compose.yaml
Slices: compose.<name>.yaml (alphabetical)

Profile Inheritance

Child profiles inherit parent slices (prepended, de-duplicated):

profiles:
  base:
    slices: [base]
  dev:
    slices: [dev]
    extends: base            # Result: [base, dev]
  full:
    slices: [extra]
    extends: dev             # Result: [base, dev, extra]

Aliases

Chain docker compose commands with &&:

aliases:
  fresh: "down -v && up --build -d"
  restart-all: "down && up -d"
  full-start: "down -v && up --build -d && logs -f"
  clean: "down -v --remove-orphans"

Usage: dox c fresh, dox c restart-all

Hooks

Available hooks: pre_up, post_up, pre_down, post_down

hooks:
  pre_up:
    - docker network prune -f
    - echo "Starting services..."
  post_up:
    - echo "Services running at http://localhost:3000"
  pre_down:
    - echo "Stopping..."
  post_down:
    - echo "Cleanup complete"

Hooks:

Run in shell context (sh -c)
Stop on first failure
Pre hooks: failure blocks main command
Post hooks: only run on success

File Discovery Priority

Explicit -f flags (highest)
dox.yaml profile configuration
Auto-discovery

Common Patterns

Simple Project

version: 1

defaults:
  profile: dev

profiles:
  dev:
    slices: [dev]
  prod:
    slices: [prod]

Corresponding files: compose.yaml, compose.dev.yaml, compose.prod.yaml

With Environment Files

version: 1

env_files:
  dev: .env.dev
  prod: .env.prod
  staging: .env.staging

profiles:
  dev:
    slices: [dev]
    env: dev
  prod:
    slices: [prod]
    env: prod

Multi-Service Stacks

version: 1

profiles:
  base:
    slices: [base]
  app:
    slices: [app]
    extends: base
  db:
    slices: [db]
    extends: base
  full:
    slices: [monitoring]
    extends: app

Files: compose.yaml, compose.base.yaml, compose.app.yaml, compose.db.yaml, compose.monitoring.yaml

Creation Workflow

Ask about project structure and environments
Determine needed profiles and slices
Add optional features (aliases, hooks, env_files)
Create dox.yaml in project root
Verify the file exists and is valid YAML
