Create hooks directory if needed
mkdir -p ~/.claude/hooks
Copy hook from plugin cache
cp ~/.claude/plugins/cache/bopen-tools/user/.claude/hooks/ < hook-name

Create hooks directory if needed
mkdir -p ~/.opencode/hooks
Copy hook from plugin cache
cp ~/.opencode/plugins/cache/bopen-tools/user/.claude/hooks/ < hook-name
.json ~/.opencode/hooks/ Then restart your agent to load the hook. Hook Details protect-env-files (Recommended) Security hook - Prevents accidental edits to environment files containing secrets. Blocks: .env , .env.local , .env.production , .env.staging Prompts for confirmation if edit attempted No performance impact uncommitted-reminder Shows git status when Claude finishes responding if there are uncommitted changes. Helps prevent forgotten commits Exit code 2 feeds back to Claude auto-git-add Automatically runs git add -A after Write/Edit/MultiEdit operations. Only stages, never commits 5 second timeout time-dir-context Adds context line to every prompt: timestamp, working directory, git branch. Example: Context: 2025-01-24 14:32:15 | /Users/you/project | Branch: main lint-on-save Runs bun lint:fix after file edits. Requires project with lint:fix script in package.json Requires bun and jq Works with statusline for lint count display lint-on-start Runs linting when session starts. Same requirements as lint-on-save auto-test-on-save Runs tests after file edits. Can be slow on large test suites Consider project-specific setup protect-shadcn-components Prevents edits to shadcn/ui component files. Only relevant for projects using shadcn/ui Installing This Skill bunx skills add b-open-io/bopen-tools --skill hook-manager Uninstalling a Hook Claude Code: rm ~/.claude/hooks/ < hook-name
