+# AGENTS.md
+
+## Build & Run
+
+- **Compile**: `npm run compile` (or `tsc -p ./`)
+- **Watch**: `npm run watch`
+- **Package extension**: `npm run build` → produces `.vsix` file
+- **Test**: Press F5 to launch extension in debug mode
+
+## Project Structure
+
+- `src/extension.ts` - Extension entry point, registers `aiCommitExt.generate` command
+- `src/opencodeService.ts` - Spawns `opencode run` CLI, parses output for commit message
+- `src/gitService.ts` - Uses VS Code Git extension API to get diffs and repo root
+
+## Key Details
+
+- Output compiled to `out/` directory
+- Extension activates only on command invocation (not on startup)
+- OpenCode CLI is required on PATH; checked via `which opencode`
+- Generated message written to SCM input box via `repository.inputBox.value`
+- Timeout: 120 seconds for OpenCode response
