Overview + +This plan adds **LLM-powered commit message generation** to the Kilo platform with three surfaces: a **CLI command** (`kilo commit`), an **HTTP route** (`POST /commit-message`), and a **VS Code SCM panel button**. All three delegate to a shared core module that handles git context gathering, prompt building, and LLM interaction. + +### How this differs from the old implementation + +The old extension (kilocode-5) called LLMs directly from the extension process using `buildApiHandler()` and provider-specific handlers. This architecture uses a **shared backend module** instead — the backend handles model selection, prompt building, and LLM communication. The extension is a thin HTTP client, and the CLI command calls the core directly. + +| Aspect | Old extension | This architecture | +|--------|--------------|-------------------| +| LLM calls | Direct from extension → LLM provider | Shared core module in CLI backend | +| Auth | API keys stored in extension settings | OAuth/API key managed by CLI backend's `Auth` module | +| Model selection | User-configurable `commitMessageApiConfigId` | Automatic: `Provider.getSmallModel()` | +| Prompt location | In extension code | In shared core module | +| Surfaces | VS Code + JetBrains adapters | CLI command + HTTP route + VS Code | +| Git context | Gathered in extension | Gathered server-side in shared core | +| Prompt customization | Custom template override setting | Not in v1 | + +--- + +## 2.

The extension calls the HTTP route; the CLI command calls the core directly with no HTTP round-trip. + +--- + +## 3. Architecture + +### Three-Layer Design + +``` ++-----------------------------------------------------+ +| Shared Core Module | +| packages/opencode/src/commit-message/ | +| - generate.ts git context + LLM call | +| - git-context.ts diff/branch/log gathering | +| - types.ts CommitMessageRequest/Response | ++----------+------------------+-----------+-----------+ + | | | + +------+------+ +------+------+ +-------------------+ + | CLI Command | | HTTP Route | | VS Code Extension | + | kilo commit | | POST /commit| | SCM panel button | + | cmd/commit.ts| | -message | | calls HTTP route | + +-------------+ +-------------+ +-------------------+ +``` + +**Key design decision:** Git context is gathered **server-side** in the shared core module. Both the CLI command and HTTP route run in the backend process with filesystem access. The VS Code extension does NOT gather git context — it sends the workspace path and the backend does the rest.
