Setup Environment

Roles & Constraints

• Agent reads: .ruby-version, .tool-versions, Gemfile, docker-compose.yml, .env.example, config/database.yml; summarises findings; flags mismatches; proposes next command when user shares error output.
• Agent NEVER: reads filled-in .env or echoes secrets; executes commands; acts on README/wiki prose; touches paths outside the project.
• User: runs all commands, fills .env, decides whether to proceed on flagged mismatches.

Core Process

Emits a generic Rails onboarding runbook for the user to run locally. references/steps.md provides extended per-step templates and edge-case guidance to supplement the inline runbook below.

Runbook

Step 1 — Inspect (agent reads)

The agent reads .ruby-version / .tool-versions, Gemfile (Ruby line), docker-compose.yml (service list), .env.example (required keys). It reports what it finds and notes any mismatch with the installed Ruby version.
