feat(claude-code): add yoloAlias option by tmaier · Pull Request #19 · tmaier/devcontainer-features

tmaier · 2026-04-21T23:15:06Z

Summary

Adds a yoloAlias boolean option (default: false) to the claude-code feature
When enabled, creates a yolo alias that expands to claude --allow-dangerously-skip-permissions
Configures the alias for bash (.bashrc), zsh (.zshrc), and fish (function file at ~/.config/fish/functions/yolo.fish)

Test plan

devcontainer features validate ./src passes
New claude_code_yolo_alias scenario tests pass
Existing claude-code scenarios remain green

Add a boolean option that creates a 'yolo' shell alias mapping to 'claude --allow-dangerously-skip-permissions' in bash, zsh, and fish.

Skip writing yolo.fish if it already exists to match bash/zsh behavior. Chown only the specific file instead of the entire functions directory. Update docs to reflect the skip-if-exists behavior.
