Instructions

Implementation Reference

• src/index.ts:130-174 (handler)

  The main execution logic for the 'check_cli_status' tool. Checks CLI availability and returns a formatted Markdown status report.

  private async handleCheckCLIStatus() {
    // Ensure detection has completed
    if (!this.cliAvailability.checked) {
      await this.detectCLIs();
    }
  
    let status = "# CLI Status Check\n\n";
  
    if (this.cliAvailability.codex) {
      status += "✓ **OpenAI CLI (Codex)**: Available\n";
    } else {
      status += "✗ **OpenAI CLI (Codex)**: Not found\n";
      status += "  - Install: `npm install -g openai`\n";
      status += "  - Set API key: `export OPENAI_API_KEY='your-key'`\n";
    }
  
    status += "\n";
  
    if (this.cliAvailability.gemini) {
      status += "✓ **Gemini CLI**: Available\n";
    } else {
      status += "✗ **Gemini CLI**: Not found\n";
      status += "  - See setup instructions in README.md\n";
      status += "  - Set API key: `export GOOGLE_API_KEY='your-key'`\n";
    }
  
    status += "\n";
  
    if (this.cliAvailability.codex && this.cliAvailability.gemini) {
      status += "**Status**: Both review CLIs are available. All features enabled.\n";
    } else if (this.cliAvailability.codex || this.cliAvailability.gemini) {
      status += "**Status**: One review CLI is available. Partial functionality enabled.\n";
    } else {
      status += "**Status**: No review CLIs available. Please install at least one to use reviews.\n";
    }
  
    return {
      content: [
        {
          type: "text",
          text: status,
        },
      ],
    };
  }

• src/index.ts:178-186 (registration)

  Registers the 'check_cli_status' tool in the tools list returned by ListToolsRequestSchema, including name, description, and input schema.

  {
    name: "check_cli_status",
    description:
      "Check which code review CLIs (Codex/OpenAI and Gemini) are installed and available. Use this before requesting reviews to see what's available.",
    inputSchema: {
      type: "object",
      properties: {},
    },
  },

• src/index.ts:105-106 (registration)

  Dispatches calls to the 'check_cli_status' handler in the CallToolRequestSchema request handler switch statement.

  case "check_cli_status":
    return await this.handleCheckCLIStatus();

• src/index.ts:56-93 (helper)

  Helper function called by the handler to detect and set the availability of Codex/OpenAI and Gemini CLI tools.

  private async detectCLIs() {
    console.error("Detecting available CLI tools...");
  
    // Check Codex CLI (codex-cli or openai)
    try {
      const { stdout } = await execAsync("codex --version", { timeout: 5000 });
      if (stdout.includes("codex-cli")) {
        this.cliAvailability.codex = true;
        console.error("✓ Codex CLI detected");
      }
    } catch (error) {
      // Try OpenAI CLI as fallback
      try {
        await execAsync("openai --version", { timeout: 5000 });
        this.cliAvailability.codex = true;
        console.error("✓ OpenAI CLI detected");
      } catch (error2) {
        this.cliAvailability.codex = false;
        console.error("✗ Codex/OpenAI CLI not found");
      }
    }
  
    // Check Gemini CLI
    try {
      await execAsync("gemini --version 2>/dev/null || gemini --help", { timeout: 5000 });
      this.cliAvailability.gemini = true;
      console.error("✓ Gemini CLI detected");
    } catch (error) {
      this.cliAvailability.gemini = false;
      console.error("✗ Gemini CLI not found");
    }
  
    this.cliAvailability.checked = true;
  
    if (!this.cliAvailability.codex && !this.cliAvailability.gemini) {
      console.error("⚠️  Warning: No review CLIs detected. Install OpenAI CLI and/or Gemini CLI to enable reviews.");
    }
  }

• src/index.ts:182-185 (schema)

  Defines the input schema for the 'check_cli_status' tool: an empty object (no parameters required).

  inputSchema: {
    type: "object",
    properties: {},
  },
