Add Agent

Add a New AI Agent Backend

Follow these steps exactly. Run bun run check after each step.

Step 1: Write Failing Tests

Create tests/agents/<name>.test.ts with:

• Test that the agent adapter builds correct CLI arguments
• Test that session ID is parsed from stdout
• Test timeout behavior

Step 2: Create Agent Adapter

Create src/agents/<name>.ts:

import type { AgentConfig } from "./types.ts";

export function buildArgs(config: AgentConfig): readonly string[] {
  // Return CLI arguments specific to this agent
}

export function parseSessionId(stdout: string): string | null {
  // Extract session ID from agent's output (for --resume support)
}

Step 3: Update Type Definitions

In src/types/events.ts, add to AgentKind:

export type AgentKind = "claude" | "codex" | "gemini" | "newagent";

In src/agents/types.ts, add to AgentType:

export type AgentType = ... | { readonly kind: "newagent" };

Step 4: Update Runner

In src/agents/runner.ts, add dispatch logic for the new agent kind.

Step 5: Update Config

In src/config/config.ts, add <name>Path to ConfigSchema. In .env.example, add <NAME>_PATH=<name>.

Step 6: Update Mention Parser

In src/events/mention.ts, add to AGENT_KEYWORDS map:

["newagent", "newagent"],

Step 7: Verify

Run bun run check. All typecheck, lint, and tests must pass.
