opencode-claude-code-hooks

Run existing Claude Code command guardrails in OpenCode without copying their commands or settings.

Install

Add the package to the OpenCode plugin array.

{
  "plugin": ["opencode-claude-code-hooks"]
}

OpenCode installs the package when it starts. The plugin reads these Claude files at every tool call.

• ~/.claude/settings.json
• <git-root>/.claude/settings.json
• <git-root>/.claude/settings.local.json

Preserved behavior

• PreToolUse and PostToolUse command hooks
• Claude matcher names such as Bash, Edit, and Write
• exit code 2 blocking
• structured deny results
• full updatedInput replacement
• post-tool feedback and additionalContext
• the Claude default command timeout of 600 seconds
• CLAUDE_PROJECT_DIR set to the Git project root

Settings are read at runtime, so editing a Claude hook does not require reinstalling this plugin.

Honest limits

• Stop cannot preserve Claude timing with OpenCode's current stable plugin API
• prompt, agent, HTTP, async, and conditional if handlers stay manual
• allow and ask results do not bypass OpenCode permissions
• malformed source settings are ignored so they do not break OpenCode startup

For a dry-run report before installation, use the compatibility route in dsh-movein.

npx claude-to-opencode --hooks-only
npx claude-to-opencode --hooks-only --apply

Verification

The test suite runs real hook child processes and checks blocking, input replacement, project-root discovery, and post-tool feedback on Linux, macOS, and Windows.
