What problem does it solve? New team members and fresh machines often lack the right CLI tools, git identity, and authentication needed by a project's workflow, causing confusing failures later. This Skill reads the team's HERO.md configuration and walks a developer through checking and fixing their local setup without touching any shared files. ## Core Features & Use Cases - Environment verification: Checks git config (identity, signing, remotes), required and recommended CLI tools, authentication status for gh/aws/gcloud/kubectl, and MCP server expectations against HERO.md. - Guided remediation: Suggests platform-appropriate install commands (brew, apt) and asks before changing any personal config like git identity or signing keys. - Check-only and recalibrate modes: Run with --check to audit without changes, or use recalibrate to tune the HERO.md fields this skill depends on. - Use Case: A developer clones the repo on a new laptop, runs the setup check, and gets a report showing gh is missing and AWS is not authenticated, with exact commands to fix both. ## Quick Start Ask the assistant to run the setup-dev skill to verify my local development environment against HERO.md and report anything missing.
