build-and-env

What problem does it solve?

This Skill eliminates the guesswork and frustration of setting up the Cambridge Beer Festival app's complex, mise-driven build toolchain from scratch, and resolves common failures like install errors, environment misconfigurations, and mismatches between local and CI builds.

Core Features & Use Cases

• Full from-scratch setup: Guides you through the project's pinned, self-contained mise bootstrap script with no manual Flutter or node installation required.
• Environment and trap troubleshooting: Covers layered environment configuration (base/dev/claude-code-web/human), MISE_ENV behavior, and known install traps like GitHub 403 errors and libgit2 transport failures.
• Introspection and parity: Provides commands to discover tasks, tool versions, and active config, plus guidance to align local builds with CI and add new tools/tasks correctly.
• Use Case: If running a mise task fails with a 403 error in the Claude Code Web sandbox, this Skill walks you through the verified MISE_ENV workaround to resolve the issue.

Quick Start

Use the build-and-env skill to set up the repo from a fresh machine, troubleshoot mise install or task execution failures, or understand why your local build behaves differently from CI.
