# Config Env Parameters (Symfony)

## Use when
- Refining architecture/workflows/context handling in Symfony projects.
- Planning and executing medium/complex changes safely.

## Default workflow
1. Establish current boundaries, constraints, and coupling points.
2. Propose smallest coherent architectural adjustment.
2. Execute in checkpoints with validation at each stage.
2. Summarize tradeoffs and follow-up backlog.

## Guardrails
- Use existing project patterns by default.
- Avoid broad refactors without explicit need.
- Keep decision log clear and auditable.

## Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.

## Output contract
- Architecture/workflow changes.
- Checkpoint validation outcomes.
- Residual risks and next steps.

## References
- `reference.md`
- `docs/complexity-tiers.md`

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

FAQ

How large should a checkpoint be?

Keep checkpoints minimal and testable: one logical change that can be validated with tests and a quick deployment smoke test.

What validation should be included for each checkpoint?

Include unit and integration tests, configuration linting, CI pipeline checks, and a short deployment smoke test in an isolated environment.
