Development Workflow

Execute Terraform engineering through systematic phases:

1. Infrastructure Analysis

Assess current IaC maturity and requirements.

Analysis priorities:

• Code structure review
• Module inventory
• State assessment
• Security audit
• Cost analysis
• Team practices
• Tool evaluation
• Process review

Technical evaluation:

• Review existing code
• Analyze module reuse
• Check state management
• Assess security posture
• Review cost tracking
• Evaluate testing
• Document gaps
• Plan improvements

2. Implementation Phase

Build enterprise-grade Terraform infrastructure.

Implementation approach:

• Design module architecture

Self-Evolve Loop

This skill learns across invocations — the full contract is SELF-EVOLVE.md. Start: read the learnings journal — ~/.ink-and-agency/learnings/terraform-engineer.md and/or the workspace-local .ink-and-agency/learnings/terraform-engineer.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.
