feat: add pluggable multi-CLI backend system
Implement BackendAdapter interface with four CLI backends: - ClaudeCodeBackend (extracted from AgentRuntime) - CodexBackend (OpenAI Codex CLI) - GeminiBackend (Google Gemini CLI) - OpenCodeBackend (OpenCode CLI) Add BackendRegistry for resolution/creation via AGENT_BACKEND env var. Refactor AgentRuntime to delegate to BackendAdapter instead of hardcoding Claude CLI. Update GatewayConfig with new env vars (AGENT_BACKEND, BACKEND_CLI_PATH, BACKEND_MODEL, BACKEND_MAX_TURNS). Includes 10 property-based test files and unit tests for edge cases.

# Design Document: Multi-CLI Backend
|
||||
|
||||
## Overview
|
||||
|
||||
This design introduces a pluggable CLI backend system for the Aetheel gateway. The current architecture hardcodes Claude Code CLI invocation directly inside `AgentRuntime`. We will extract a `BackendAdapter` interface and provide four implementations (Claude, Codex, Gemini, OpenCode), each encapsulating CLI spawning, argument construction, output parsing, and session management. A `BackendRegistry` resolves the active backend from environment configuration at startup, validates it, and injects it into `AgentRuntime`.
|
||||
|
||||
The key design goals are:
|
||||
- Zero behavioral change for existing Claude deployments (backward compatible defaults)
|
||||
- Each backend is a self-contained module with no cross-dependencies
|
||||
- The rest of the gateway (event processing, Discord integration, session management) remains untouched
|
||||
- Output is normalized into a single `EventResult` shape regardless of backend
|
||||
|
||||

Backend->>Backend: parse output into EventResult
|
||||
Backend-->>Runtime: EventResult { responseText, sessionId, isError }
|
||||
```
|
||||
|
||||
## Components and Interfaces
|
||||
|
||||
### BackendAdapter Interface
|
||||
|
||||
```typescript
|
||||
export interface BackendAdapterConfig {
|
||||
cliPath: string;
|
||||
workingDir: string;
|
||||
queryTimeoutMs: number;
|
||||
allowedTools: string[];
|
||||
maxTurns: number;
|
||||
model?: string;
|
||||
}
|
||||
|
||||
export interface EventResult {
|
||||
responseText?: string;
|
||||
sessionId?: string;
|
||||
isError: boolean;
|
||||
}
|
||||
|
||||
export type StreamCallback = (text: string) => Promise<void>;
|
||||
|
||||
export interface BackendAdapter {
|
||||
/** Unique identifier for this backend (e.g., "claude", "codex") */
|
||||
name(): string;
|
||||
|
||||
/** Execute a prompt and return normalized results */
|
||||
execute(
|
||||
prompt: string,
|
||||
systemPrompt: string,
|
||||
sessionId?: string,
|
||||
onStream?: StreamCallback,
|
||||
): Promise<EventResult>;
|
||||
|
||||
/** Validate that the CLI binary is reachable and executable */
|
||||
validate(): Promise<boolean>;
|
||||
}
|
||||
```
|
||||
|
||||
### ClaudeCodeBackend
|
||||
|
||||
Preserves the existing behavior extracted from `AgentRuntime.runClaude()`.
|
||||
|
||||
- Writes system prompt to a temp file, passes via `--append-system-prompt-file`
|
||||
- Spawns: `claude -p <prompt> --output-format json --dangerously-skip-permissions --append-system-prompt-file <file>`
|
||||
- Session resume: `--resume <sessionId>`
|
||||
- Tool filtering: `--allowedTools <tool>` for each tool
|
||||
- Max turns: `--max-turns <n>`
|
||||
- Parses JSON array output for `system/init` (session_id) and `result` objects
|
||||
|
||||
### CodexBackend
|
||||
|
||||
- Spawns: `codex exec <prompt> --json --dangerously-bypass-approvals-and-sandbox`
|
||||
- Working directory: `--cd <path>`
|
||||
- Session resume: `codex exec resume <sessionId>` with follow-up prompt
|
||||
- Parses newline-delimited JSON events for the final assistant message
|
||||
- System prompt: passed via `--config system_prompt=<text>` or prepended to prompt
|
||||
|
||||
### GeminiBackend
|
||||
|
||||
- Spawns: `gemini <prompt> --output-format json --approval-mode yolo`
|
||||
- Session resume: `--resume <sessionId>`
|
||||
- Parses JSON output for response text
|
||||
- System prompt: prepended to prompt text (Gemini CLI has no system prompt file flag in non-interactive mode)
|
||||
|
||||
### OpenCodeBackend
|
||||
|
||||
- Spawns: `opencode run <prompt> --format json`
|
||||
- Session resume: `--session <sessionId> --continue`
|
||||
- Model selection: `--model <provider/model>`
|
||||
- Parses JSON events for final response text
|
||||
- System prompt: prepended to prompt text
|
||||
|
||||
### BackendRegistry
|
||||
|
||||
```typescript
|
||||
export type BackendName = "claude" | "codex" | "gemini" | "opencode";
|
||||
|
||||
export function createBackend(
|
||||
name: BackendName,
|
||||
config: BackendAdapterConfig,
|
||||
): BackendAdapter;
|
||||
|
||||
export function resolveBackendName(raw: string | undefined): BackendName;
|
||||
```
|
||||
|
||||
- `resolveBackendName` maps the `AGENT_BACKEND` env var to a valid `BackendName`, defaulting to `"claude"`, or throws with a descriptive error listing valid options
|
||||
- `createBackend` instantiates the correct implementation
|
||||
|
||||
### AgentRuntime Refactoring
|
||||
|
||||
The constructor changes from:
|
||||
```typescript
|
||||
constructor(config, sessionManager, markdownConfigLoader, systemPromptAssembler, hookManager)
|
||||
```
|
||||
to:
|
||||
```typescript
|
||||
constructor(config, backend, sessionManager, markdownConfigLoader, systemPromptAssembler, hookManager)
|
||||
```
|
||||
|
||||
- `executeClaude()` and `runClaude()` are replaced by `this.backend.execute()`
|
||||
- The `ClaudeJsonResponse` interface is removed from `AgentRuntime`
|
||||
- `EventResult` mapping: the backend's `EventResult` maps directly to the gateway's existing `EventResult` interface (adding `targetChannelId` in the runtime layer)
|
||||
|
||||
### GatewayConfig Changes
|
||||
|
||||
```typescript
|
||||
export interface GatewayConfig {
|
||||
// ... existing fields ...
|
||||
agentBackend: BackendName; // NEW: replaces implicit claude-only
|
||||
backendCliPath: string; // NEW: replaces claudeCliPath
|
||||
backendModel?: string; // NEW: optional model override
|
||||
backendMaxTurns: number; // NEW: configurable max turns
|
||||
// claudeCliPath removed
|
||||
}
|
||||
```
|
||||
|
||||
New environment variables:
|
||||
- `AGENT_BACKEND` → `agentBackend` (default: `"claude"`)
|
||||
- `BACKEND_CLI_PATH` → `backendCliPath` (default: backend-specific, e.g., `"claude"`, `"codex"`, `"gemini"`, `"opencode"`)
|
||||
- `BACKEND_MODEL` → `backendModel`
|
||||
- `BACKEND_MAX_TURNS` → `backendMaxTurns` (default: `25`)
|
||||
|
||||
## Data Models
|
||||
|
||||
### EventResult (Backend)
|
||||
|
||||
```typescript
|
||||
export interface BackendEventResult {
|
||||
responseText?: string;
|
||||
sessionId?: string;
|
||||
isError: boolean;
|
||||
}
|
||||
```
|
||||
|
||||
This is the normalized output from any backend. The `AgentRuntime` maps it to the gateway's `EventResult`:
|
||||
|
||||
```typescript
|
||||
// Gateway EventResult (existing, unchanged)
|
||||
export interface EventResult {
|
||||
responseText?: string;
|
||||
targetChannelId?: string;
|
||||
sessionId?: string;
|
||||
error?: string;
|
||||
}
|
||||
```
|
||||
|
||||
Mapping logic:
|
||||
```typescript
|
||||
if (backendResult.isError) {
|
||||
return { error: backendResult.responseText, targetChannelId };
|
||||
} else {
|
||||
return { responseText: backendResult.responseText, targetChannelId, sessionId: backendResult.sessionId };
|
||||
}
|
||||
```
|
||||
|
||||
### BackendAdapterConfig
|
||||
|
||||
```typescript
|
||||
export interface BackendAdapterConfig {
|
||||
cliPath: string; // Path to CLI binary
|
||||
workingDir: string; // Working directory for CLI process
|
||||
queryTimeoutMs: number; // Timeout before killing the process
|
||||
allowedTools: string[]; // Tools to whitelist (backend-specific support)
|
||||
maxTurns: number; // Max agentic turns
|
||||
model?: string; // Optional model override
|
||||
}
|
||||
```
|
||||
|
||||
### CLI Output Formats
|
||||
|
||||
| Backend | Output Format | Session ID Source | Result Source |
|
||||
|-----------|------------------------------|--------------------------------------|-----------------------------------|
|
||||
| Claude | JSON array | `system/init` object `.session_id` | `result` object `.result` |
|
||||
| Codex | Newline-delimited JSON | Session ID from exec metadata | Final assistant message content |
|
||||
| Gemini | JSON object | Session metadata in output | Response text field |
|
||||
| OpenCode | JSON events | Session field in response | Final response text |
|
||||
|
||||
|
||||
## Correctness Properties
|
||||
|
||||
*A property is a characteristic or behavior that should hold true across all valid executions of a system — essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.*
|
||||
|
||||
### Property 1: Claude backend required flags
|
||||
|
||||
*For any* prompt string, system prompt string, and allowed tools list, the Claude backend's generated argument list SHALL always contain `-p`, `--output-format json`, `--dangerously-skip-permissions`, `--append-system-prompt-file`, `--max-turns`, and one `--allowedTools` entry per configured tool.
|
||||
|
||||
**Validates: Requirements 2.2, 2.5, 2.6**
|
||||
|
||||
### Property 2: Codex backend required flags
|
||||
|
||||
*For any* prompt string and working directory, the Codex backend's generated argument list SHALL always contain the `exec` subcommand, `--json`, `--dangerously-bypass-approvals-and-sandbox`, and `--cd <workingDir>`.
|
||||
|
||||
**Validates: Requirements 3.2, 3.3, 3.4, 3.5**
|
||||
|
||||
### Property 3: Gemini backend required flags
|
||||
|
||||
*For any* prompt string, the Gemini backend's generated argument list SHALL always contain the prompt as a positional argument, `--output-format json`, and `--approval-mode yolo`.
|
||||
|
||||
**Validates: Requirements 4.2, 4.3, 4.4**
|
||||
|
||||
### Property 4: OpenCode backend required flags
|
||||
|
||||
*For any* prompt string and optional model string, the OpenCode backend's generated argument list SHALL always contain the `run` subcommand, `--format json`, and when a model is configured, `--model <model>`.
|
||||
|
||||
**Validates: Requirements 5.2, 5.3, 5.5**
|
||||
|
||||
### Property 5: Session resume args across backends
|
||||
|
||||
*For any* backend and any non-empty session ID string, the generated argument list SHALL include the backend-specific session resume flags: `--resume <id>` for Claude, `resume <id>` subcommand for Codex, `--resume <id>` for Gemini, and `--session <id> --continue` for OpenCode. When no session ID is provided, no session-related flags SHALL appear.
|
||||
|
||||
**Validates: Requirements 2.3, 3.7, 4.5, 5.4**
|
||||
|
||||
### Property 6: Output parsing extracts correct fields
|
||||
|
||||
*For any* valid backend-specific JSON output containing a response text and session ID, the backend's parser SHALL produce a `BackendEventResult` where `responseText` matches the expected response content and `sessionId` matches the expected session identifier.
|
||||
|
||||
**Validates: Requirements 2.4, 3.6, 4.6, 5.6, 8.1**
|
||||
|
||||
### Property 7: Backend name resolution
|
||||
|
||||
*For any* string, `resolveBackendName` SHALL return the corresponding `BackendName` if the string is one of `"claude"`, `"codex"`, `"gemini"`, or `"opencode"`, SHALL return `"claude"` when the input is `undefined`, and SHALL throw a descriptive error for any other string value.
|
||||
|
||||
**Validates: Requirements 6.1, 6.2, 6.3, 6.5**
|
||||
|
||||
### Property 8: Non-zero exit code produces error result
|
||||
|
||||
*For any* backend, any non-zero exit code, and any stderr string, the backend SHALL return a `BackendEventResult` with `isError` set to `true` and `responseText` containing the stderr content.
|
||||
|
||||
**Validates: Requirements 8.2**
|
||||
|
||||
### Property 9: EventResult mapping preserves semantics
|
||||
|
||||
*For any* `BackendEventResult` and target channel ID, the mapping to the gateway's `EventResult` SHALL set `error` to `responseText` when `isError` is true (with no `responseText` on the gateway result), and SHALL set `responseText` and `sessionId` when `isError` is false (with no `error` on the gateway result). `targetChannelId` SHALL always be set.
|
||||
|
||||
**Validates: Requirements 10.3**
|
||||
|
||||
### Property 10: Session ID storage after backend execution
|
||||
|
||||
*For any* channel ID and any `BackendEventResult` containing a non-undefined `sessionId`, after the `AgentRuntime` processes the result, the `SessionManager` SHALL contain that session ID for that channel. When `sessionId` is undefined, the session manager SHALL not be updated for that channel.
|
||||
|
||||
**Validates: Requirements 10.4**
|
||||
|
||||
## Error Handling
|
||||
|
||||
### CLI Process Errors
|
||||
|
||||
| Error Condition | Handling |
|
||||
|---|---|
|
||||
| CLI binary not found | `validate()` returns false at startup → gateway logs error with backend name and path, exits with code 1 |
|
||||
| Non-zero exit code | Backend sets `isError: true`, includes stderr (truncated to 500 chars) in `responseText` |
|
||||
| Query timeout | Backend kills process with SIGTERM after `queryTimeoutMs`, returns `{ isError: true, responseText: "Query timed out" }` |
|
||||
| Invalid JSON output | Backend returns `{ isError: true, responseText: "Failed to parse CLI output" }` |
|
||||
| Session corruption | `AgentRuntime` detects session-related error messages, removes session from `SessionManager`, allows retry without session |
|
||||
|
||||
### Configuration Errors
|
||||
|
||||
| Error Condition | Handling |
|
||||
|---|---|
|
||||
| Invalid `AGENT_BACKEND` value | `resolveBackendName` throws with message listing valid options; gateway fails at startup |
|
||||
| Invalid `BACKEND_MAX_TURNS` | Falls back to default (25), logs warning |
|
||||
| Unsupported option for backend | Logs warning, ignores the option (e.g., `ALLOWED_TOOLS` for backends that don't support tool filtering) |
|
||||
|
||||
### Retry Strategy
|
||||
|
||||
The existing `withRetry` mechanism in `AgentRuntime` continues to wrap backend execution calls:
|
||||
- Max 3 retries with exponential backoff (5s base)
|
||||
- Transient errors (timeout, spawn failure, crash) trigger retry
|
||||
- Session corruption errors are non-retryable; session is cleared and the next attempt starts fresh
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Property-Based Testing
|
||||
|
||||
Library: [fast-check](https://github.com/dubzzz/fast-check) for TypeScript property-based testing.
|
||||
|
||||
Each property test runs a minimum of 100 iterations. Each test is tagged with a comment referencing the design property:
|
||||
|
||||
```typescript
|
||||
// Feature: multi-cli-backend, Property 1: Claude backend required flags
|
||||
```
|
||||
|
||||
Properties to implement:
|
||||
- **Property 1–4**: Generate random prompt strings, system prompts, tool lists, and config values. Call each backend's arg-building function and assert required flags are present.
|
||||
- **Property 5**: Generate random session ID strings (including empty/undefined). For each backend, verify session flags appear only when a session ID is provided.
|
||||
- **Property 6**: Generate random valid JSON output structures per backend format. Parse and verify extracted fields match.
|
||||
- **Property 7**: Generate random strings. Verify resolution behavior (valid → correct BackendName, undefined → "claude", invalid → throws).
|
||||
- **Property 8**: Generate random exit codes (non-zero) and stderr strings. Verify error result shape.
|
||||
- **Property 9**: Generate random `BackendEventResult` objects. Verify mapping to gateway `EventResult`.
|
||||
- **Property 10**: Generate random channel IDs and `BackendEventResult` objects with/without session IDs. Verify session manager state.
|
||||
|
||||
### Unit Testing
|
||||
|
||||
Unit tests complement property tests for specific examples and edge cases:
|
||||
- Each backend's `validate()` method with mocked filesystem
|
||||
- Timeout behavior with a mock slow process
|
||||
- Startup flow: valid config → backend created → validated → injected into runtime
|
||||
- Startup flow: invalid backend name → descriptive error
|
||||
- Default config values when env vars are unset
|
||||
- Streaming callback invocation during output parsing
|
||||
- Session corruption detection and cleanup
|
||||
|
||||
### Integration Testing
|
||||
|
||||
- End-to-end test with a mock CLI script that echoes JSON in each backend's format
|
||||
- Verify the full flow: config → registry → backend → execute → parse → EventResult

# Requirements Document
|
||||
|
||||
## Introduction
|
||||
|
||||
The gateway currently hardcodes Claude Code CLI as its sole agent backend. This feature introduces a pluggable CLI backend system that allows operators to choose between Claude Code CLI, OpenCode CLI, Codex CLI, and Gemini CLI. Each backend has different command-line interfaces, output formats, and session management semantics. The system must abstract these differences behind a unified interface so the rest of the gateway (event processing, session management, Discord integration) remains unchanged.
|
||||
|
||||
## Glossary
|
||||
|
||||
- **Gateway**: The Discord-to-agent bridge application (Aetheel) that receives prompts and dispatches them to a CLI backend
|
||||
- **CLI_Backend**: A pluggable module that knows how to spawn a specific CLI tool, pass prompts and system prompts, parse output, and manage sessions
|
||||
- **Backend_Registry**: The component that holds all available CLI_Backend implementations and resolves the active one from configuration
|
||||
- **Agent_Runtime**: The existing `AgentRuntime` class that orchestrates event processing; it will delegate CLI execution to the active CLI_Backend
|
||||
- **Backend_Adapter**: An interface that each CLI_Backend must implement, defining spawn, parse, and session operations
|
||||
- **Session_ID**: An opaque string returned by a CLI backend that allows resuming a prior conversation
|
||||
- **Event_Result**: The normalized response object returned by any CLI_Backend after processing a prompt
|
||||
|
||||
## Requirements
|
||||
|
||||
### Requirement 1: Backend Adapter Interface
|
||||
|
||||
**User Story:** As a developer, I want a common interface for all CLI backends, so that the gateway can interact with any backend without knowing its implementation details.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Backend_Adapter SHALL define a method to execute a prompt given a prompt string, a system prompt string, an optional Session_ID, and an optional streaming callback
|
||||
2. THE Backend_Adapter SHALL return an Event_Result containing the response text, an optional Session_ID for continuation, and an error flag
|
||||
3. THE Backend_Adapter SHALL define a method to return the backend name as a string identifier
|
||||
4. THE Backend_Adapter SHALL define a method to validate that the CLI tool is reachable on the system (e.g., binary exists at configured path)
|
||||
|
||||
### Requirement 2: Claude Code CLI Backend
|
||||
|
||||
**User Story:** As an operator, I want the existing Claude Code CLI integration preserved as a backend, so that current deployments continue working without changes.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Claude_Code_Backend SHALL implement the Backend_Adapter interface
|
||||
2. THE Claude_Code_Backend SHALL spawn the Claude CLI with `-p`, `--output-format json`, `--dangerously-skip-permissions`, and `--append-system-prompt-file` flags

|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||

|
||||
|
||||
### Requirement 6: Backend Selection via Configuration
|
||||
|
||||
**User Story:** As an operator, I want to select which CLI backend to use through environment variables, so that I can switch backends without code changes.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Gateway SHALL read an `AGENT_BACKEND` environment variable to determine which CLI_Backend to activate
|
||||
2. THE Gateway SHALL accept values `claude`, `codex`, `gemini`, and `opencode` for the `AGENT_BACKEND` variable
|
||||
3. WHEN `AGENT_BACKEND` is not set, THE Gateway SHALL default to `claude` for backward compatibility
|
||||
4. THE Gateway SHALL read a `BACKEND_CLI_PATH` environment variable to override the default binary path for the selected backend
|
||||
5. IF an unrecognized value is provided for `AGENT_BACKEND`, THEN THE Gateway SHALL fail at startup with a descriptive error message listing valid options
|
||||
|
||||
### Requirement 7: Backend-Specific Configuration
|
||||
|
||||
**User Story:** As an operator, I want to pass backend-specific settings through environment variables, so that I can tune each backend's behavior.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Gateway SHALL read `BACKEND_MODEL` environment variable to pass a model override to the active CLI_Backend
|
||||
2. THE Gateway SHALL read `BACKEND_MAX_TURNS` environment variable to limit the number of agentic turns, defaulting to 25
|
||||
3. WHEN the active backend does not support a configured option, THE Gateway SHALL log a warning and ignore the unsupported option
|
||||
4. THE Gateway SHALL pass the existing `ALLOWED_TOOLS` configuration to backends that support tool filtering
|
||||
|
||||
### Requirement 8: Unified Output Parsing
|
||||
|
||||
**User Story:** As a developer, I want each backend to normalize its output into a common format, so that downstream processing (Discord messaging, archiving) works identically regardless of backend.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Backend_Adapter SHALL return Event_Result with fields: `responseText` (string or undefined), `sessionId` (string or undefined), and `isError` (boolean)
|
||||
2. WHEN a CLI_Backend process exits with a non-zero exit code, THE Backend_Adapter SHALL set `isError` to true and include the stderr content in `responseText`
|
||||
3. WHEN a CLI_Backend process exceeds the configured query timeout, THE Backend_Adapter SHALL terminate the process and return an Event_Result with `isError` set to true and `responseText` set to "Query timed out"
|
||||
4. THE Backend_Adapter SHALL support an optional streaming callback that receives partial result text as the CLI process produces output
|
||||
|
||||
### Requirement 9: Backend Validation at Startup
|
||||
|
||||
**User Story:** As an operator, I want the gateway to verify the selected backend is available at startup, so that I get immediate feedback if the CLI tool is missing or misconfigured.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. WHEN the Gateway starts, THE Backend_Registry SHALL invoke the active CLI_Backend's validation method
|
||||
2. IF the validation fails, THEN THE Gateway SHALL log an error with the backend name and configured path, and exit with a non-zero exit code
|
||||
3. THE validation method SHALL check that the configured CLI binary path is executable
|
||||
|
||||
### Requirement 10: Agent Runtime Refactoring
|
||||
|
||||
**User Story:** As a developer, I want the AgentRuntime to delegate CLI execution to the Backend_Adapter, so that the runtime is decoupled from any specific CLI tool.
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
1. THE Agent_Runtime SHALL accept a Backend_Adapter instance through its constructor instead of directly referencing Claude CLI configuration
|
||||
2. THE Agent_Runtime SHALL call the Backend_Adapter's execute method instead of spawning CLI processes directly
|
||||
3. THE Agent_Runtime SHALL map the Backend_Adapter's Event_Result to the existing EventResult interface used by the rest of the gateway
|
||||
4. WHEN the Backend_Adapter returns a Session_ID, THE Agent_Runtime SHALL store the Session_ID in the Session_Manager for the corresponding channel
