Original Pull Request: https://github.com/git-ai-project/git-ai/pull/275

State: closed
Merged: Yes

Summary

Adds OpenCode agent support for git-ai, implementing issue #232.

Changes

src/commands/install_hooks.rs: Added check_opencode(), install_opencode_hooks(), and opencode_plugin_path() functions following existing patterns for Claude Code/Cursor
agent-support/opencode/git-ai.ts: New TypeScript plugin that integrates with OpenCode's plugin system

How it works

The plugin hooks into OpenCode's tool execution lifecycle:

chat.params - Captures the active model (supports mid-session model switches)
tool.execute.before - Creates human checkpoint before AI edits
tool.execute.after - Creates AI checkpoint after edits with model attribution

Key features:

Detects git repo from file path using git rev-parse --show-toplevel (works regardless of OpenCode's working directory)
Gracefully handles non-git directories and missing git-ai installation
Tracks edit and write tools

Testing

All 5 new OpenCode-specific unit tests pass
All 164 existing tests pass
Manually tested plugin with model switching (Claude Opus → Gemini → Claude Sonnet)

Installation

After merging, users can install with:

git-ai install-hooks

The plugin is installed to ~/.config/opencode/plugin/git-ai.ts

Closes #232
