arn-infra-ensure-config

name	arn-infra-ensure-config
description	This skill should be used when the user says "ensure config", "check arn infra config", "arn-infra-ensure-config", "verify arn infra setup", or wants to verify that Arness Infra configuration is present for the current project. This skill is primarily consumed as a reference by entry-point skills (arn-infra-wizard, arn-infra-assess) which read the `references/step-0-fast-path.md` reference as Step 0 before proceeding with their workflow.
version	1.1.0

Arness Infra Ensure Config

Verify and establish Arness Infra configuration for the current project. This skill guarantees that a valid user profile and ## Arness section exist before any Arness Infra 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-infra-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-infra-ensure-config), this skill bypasses the cache and runs the full validation flow.

Workflow

Read ${CLAUDE_PLUGIN_ROOT}/skills/arn-infra-ensure-config/references/ensure-config.md and follow its instructions (Layers 1–3, then Layer 4 cache write).
