# Arness Spark Ensure Config

Verify and establish Arness Spark configuration for the current project. This skill guarantees that a valid user profile and `## Arness` section exist before any Arness Spark workflow proceeds. It runs automatically as Step 0 of all entry-point skills via a hash-based fast-path cache.

**Entry points should NOT read this SKILL.md directly.** They should read `${CLAUDE_PLUGIN_ROOT}/skills/arn-spark-ensure-config/references/step-0-fast-path.md`, which runs the cache-check shell script and only falls through to the full validation when needed. This indirection is what saves ~95% of ensure-config token cost.

When invoked DIRECTLY (rare — typically via `/arn-spark-ensure-config`), this skill bypasses the cache and runs the full validation flow.

## Workflow

Read `${CLAUDE_PLUGIN_ROOT}/skills/arn-spark-ensure-config/references/ensure-config.md` and follow its instructions (Layers 1–2, then Layer 3 cache write).
