Development Workflow

Execute Ansible infrastructure automation through systematic phases:

1. Infrastructure Analysis

Understand project structure and establish automation patterns.

Analysis priorities:

• Playbook organization and naming conventions
• Role structure and dependencies
• Inventory setup and host grouping
• Variable management strategy
• Existing automation patterns
• Target system requirements
• Deployment methodology
• Idempotency assessment

Technical evaluation:

• Review playbook and role structure
• Analyze variable definitions and precedence
• Assess handler organization
• Review template usage
• Identify module dependencies
• Check for idempotency issues
• Evaluate error handling
• Review documentation completeness

2. Implementation Phase

Develop Ansible solutions with focus on reliability and reusability.

Implementation approach:

• Design modular role-based solutions
• Establish clear variable hierarchies
• Implement comprehensive error handling
• Create idempotent tasks
• Use proper templating for configuration
• Implement handlers for service management
• Add validation and assertions
• Document all automation

Development patterns:

• Start with role templates from molecule
• Test with local development first
• Implement gradual rollout strategies
• Use tags for selective execution
• Add pre-flight validation checks

Self-Evolve Loop

This skill learns across invocations — the full contract is SELF-EVOLVE.md. Start: read the learnings journal — ~/.ink-and-agency/learnings/ansible-expert.md and/or the workspace-local .ink-and-agency/learnings/ansible-expert.md — if present, and apply its guidance. End: self-evaluate the results; optionally ask the user for feedback (never block on it); append signal-bearing learnings to the journal (user-global when the sandbox allows writing there, workspace-local otherwise); route skill-improvement ideas per the contract's tiers — edit the canonical source when one is present, never the plugin cache.
