• src/tools/terraform/validate.ts:6-52 (handler)

  The implementation of the terraform_validate tool, which executes `terraform validate` and `terraform fmt -check` commands.

  export async function terraformValidate(args: Record<string, unknown>): Promise<string> {
    const directory = args.directory as string;
    if (!directory) throw new Error("Terraform directory is required");
  
    const lines: string[] = [];
  
    // Validate
    try {
      const { stdout } = await execFileAsync("terraform", ["validate", "-json"], {
        cwd: directory,
        timeout: 30000,
      });
      const result = JSON.parse(stdout);
      if (result.valid) {
        lines.push("Validation: PASSED");
      } else {
        lines.push("Validation: FAILED");
        for (const diag of result.diagnostics || []) {
          lines.push(`  ${diag.severity}: ${diag.summary}`);
          if (diag.detail) lines.push(`    ${diag.detail}`);
        }
      }
    } catch (error: any) {
      lines.push(`Validation error: ${error.stderr || error.message}`);
    }
  
    // Format check
    try {
      const { stdout } = await execFileAsync("terraform", ["fmt", "-check", "-diff"], {
        cwd: directory,
        timeout: 30000,
      });
      if (stdout.trim()) {
        lines.push("", "Formatting issues:", stdout);
      } else {
        lines.push("", "Formatting: OK");
      }
    } catch (error: any) {
      if (error.stdout?.trim()) {
        lines.push("", "Formatting issues:", error.stdout);
      } else {
        lines.push("", `Format check error: ${error.message}`);
      }
    }
  
    return lines.join("\n");
  }

      type: "object" as const,
      properties: {
        directory: { type: "string", description: "Directory containing Terraform files" },
      },
      required: ["directory"],
    },
  },

• src/tools/terraform/index.ts:78-78 (registration)
