config-env-parameters_skill

Overview

This skill applies production-grade Symfony architecture and execution workflows focused on configuration environment parameters. It guides small, controlled architecture adjustments and staged execution with clear checkpoints and validation. The goal is safe, auditable changes that minimize risk and preserve existing project patterns.

How this skill works

The skill inspects current boundaries, coupling points, and environment parameter usage across Symfony services and configuration files. It proposes the smallest coherent change set, sequences work into checkpoints, and validates each stage against functional and deployment expectations. After execution it summarizes tradeoffs, residual risks, and recommended follow-up tasks.

When to use it

• Refining how env parameters are injected and resolved across Symfony services
• Planning medium-complexity changes that touch config, DI, and runtime behavior
• Executing staged changes that require validation in dev, staging, and prod
• When you need an auditable decision log for configuration and architecture changes
• Introducing environment-based feature toggles or runtime config scoping

Best practices

• Default to existing project patterns; avoid broad refactors unless justified
• Define minimal, reversible change sets and run them as checkpoints
• Validate at each checkpoint: unit tests, integration tests, and deployment smoke checks
• Keep a clear decision log with rationale, alternatives considered, and rollback criteria
• Surface residual risks and add them to the follow-up backlog with owners

Example use cases

• Scoped migration of env parameter parsing from parameters.yml to native Symfony env vars
• Controlled rollout of parameter-driven feature flags with staged validation
• Refining DI container bindings that depend on environment parameters without disrupting runtime
• Defining execution workflows for safe deployment of config changes across environments
• Auditable change process for tightening secrets handling and scope of env parameters
