Five OpenAI-compatible providers join the library as first-class constructors
(llm.DeepSeek, llm.Moonshot, llm.XAI, llm.Groq, llm.Ollama). Their wire-level
implementation is shared via a new v2/openaicompat package which is the
extracted guts of the old v2/openai provider; each provider supplies its own
Rules value to declare per-model constraints (e.g., DeepSeek Reasoner rejects
tools and temperature, Moonshot/xAI accept images only on *-vision* models,
Groq rejects audio input). v2/openai itself becomes a thin wrapper that sets
RestrictTemperature for o-series and gpt-5 models.

A new provider registry (v2/registry.go) exposes llm.Providers() and drives
the TUI's provider picker so adding a provider in future is a single-file
change.

The TUI at cmd/llm was migrated from v1 to v2 and moved to v2/cmd/llm. With
nothing else depending on v1, the v1 code at the repo root (all .go files,
schema/, internal/, provider/, root go.mod/go.sum) is deleted.

# CLAUDE.md for go-llm # CLAUDE.md for go-llm
## Build and Test Commands All Go code now lives under `v2/`. The module path is
- Build project: `go build ./...` `gitea.stevedudenhoeffer.com/steve/go-llm/v2`. There is no module at the
- Run all tests: `go test ./...` repository root anymore; the v1 code at the root was deleted after all
- Run specific test: `go test -v -run <TestName> ./...` consumers migrated to v2.
- Tidy dependencies: `go mod tidy`
## Code Style Guidelines See `v2/CLAUDE.md` for build/test commands and per-package guidance.
- **Indentation**: Use standard Go tabs for indentation.
- **Naming**:
- Use `camelCase` for internal/private variables and functions.
- Use `PascalCase` for exported types, functions, and struct fields.
- Interface names should be concise (e.g., `LLM`, `ChatCompletion`).
- **Error Handling**:
- Always check and handle errors immediately.
- Wrap errors with context using `fmt.Errorf("%w: ...", err)`.
- Use the project's internal `Error` struct in `error.go` when differentiating between error types is needed.
- **Project Structure**:
- `llm.go`: Contains core interfaces (`LLM`, `ChatCompletion`) and shared types (`Message`, `Role`, `Image`).
- Provider implementations are in `openai.go`, `anthropic.go`, and `google.go`.
- Schema definitions for tool calling are in the `schema/` directory.
- `mcp.go`: MCP (Model Context Protocol) client integration for connecting to MCP servers.
- **Imports**: Organize imports into groups: standard library, then third-party libraries.
- **Documentation**: Use standard Go doc comments for exported symbols.
- **README.md**: The README.md file should always be kept up to date with any significant changes to the project.
## CLI Tool ## CLI
- Build CLI: `go build ./cmd/llm`
- Run CLI: `./llm` (or `llm.exe` on Windows)
- Run without building: `go run ./cmd/llm`
### CLI Features The interactive TUI lives at `v2/cmd/llm`:
- Interactive TUI for testing all go-llm features
- Support for OpenAI, Anthropic, and Google providers
- Image input (file path, URL, or base64)
- Tool/function calling with demo tools
- Temperature control and settings
### Key Bindings ```
- `Enter` - Send message cd v2 && go run ./cmd/llm
- `Ctrl+I` - Add image
- `Ctrl+T` - Toggle tools panel
- `Ctrl+P` - Change provider
- `Ctrl+M` - Change model
- `Ctrl+S` - Settings
- `Ctrl+N` - New conversation
- `Esc` - Exit/Cancel
## MCP (Model Context Protocol) Support
The library supports connecting to MCP servers to use their tools. MCP servers can be connected via:
- **stdio**: Run a command as a subprocess
- **sse**: Connect to an SSE endpoint
- **http**: Connect to a streamable HTTP endpoint
### Usage Example
```go
ctx := context.Background()
// Create and connect to an MCP server
server := &llm.MCPServer{
Name: "my-server",
Command: "my-mcp-server",
Args: []string{"--some-flag"},
}
if err := server.Connect(ctx); err != nil {
log.Fatal(err)
}
defer server.Close()
// Add the server to a toolbox
toolbox := llm.NewToolBox().WithMCPServer(server)
// Use the toolbox in requests - MCP tools are automatically available
req := llm.Request{
Messages: []llm.Message{{Role: llm.RoleUser, Text: "Use the MCP tool"}},
Toolbox: toolbox,
}
``` ```
### MCPServer Options It iterates `llm.Providers()` so every registered provider (OpenAI, Anthropic,
- `Name`: Friendly name for logging Google, DeepSeek, Moonshot, xAI, Groq, Ollama) appears in the picker
- `Command`: Command to run (for stdio transport) automatically. Status is derived from each provider's env var; Ollama shows as
- `Args`: Command arguments "(local)" because it needs no key.
- `Env`: Additional environment variables
- `URL`: Endpoint URL (for sse/http transport) ### Key bindings
- `Transport`: "stdio" (default), "sse", or "http" - `Enter` — Send message
- `Ctrl+I` — Add image
- `Ctrl+T` — Toggle tools panel
- `Ctrl+P` — Change provider
- `Ctrl+M` — Change model
- `Ctrl+S` — Settings
- `Ctrl+N` — New conversation
- `Esc` — Exit/Cancel
